[0032] Detailed Description

[0033] Like features across different arrangements will generally be labelled using the same reference number.

[0034] Figure 1 illustrates the inner padding 100 for a padded sheet or mattress according to an embodiment of the disclosure. The inner padding 100 comprises a plurality of holes 102, 104 arranged in an array across the inner padding 100. Each of the plurality of holes 102, 104 comprises a width. Where the holes 102, 104 are a circular hole the width may be the diameter of the hole. Where the hole 102, 104 is a square hole the width may be the distance between two parallel sides of the hole 102, 104. Alternatively, the width may be taken as the distance between two opposite vertices of the hole. Where the hole 102, 104 is triangular the width of the hole may be the distance between a vertex and an opposite side of the hole 102, 104. Wherein the hole is any other shape, the width may be the furthest distance between two opposite sides of a hole. The width may be dependent on the location of the hole 102, 104 in the array. For example holes 102, 104 may be positioned in the array based on their width. In one such embodiment, holes 102, 104 of a smaller width may be placed proximate to an outer perimeter 110 of the inner padding 100 and holes 102, 104 of a larger width may be placed in the centre of the inner padding 100.

[0035] In some embodiments, the holes 102, 104 are arranged such that the inner padding 100 comprises a plurality of areas, with the holes 102, 104 of each area having a single width. A periphery of the mattress may form a first area. A central area within the periphery of the inner padding 100 may form a second area.

[0036] The inner padding 100 may comprise three or more areas. A first area of the inner padding 100 may have holes 102, 104 of the same width as holes in a second area of the mattress 100. The first area and the second area of the padded sheet may be separated by a third area, wherein holes of the third area of the inner padding 100 are of a different width to the holes of the first area and the second area of the inner padding 100. Alternatively, each area of the inner padding 100 may comprise holes 102, 104 of different widths.Alternatively or additionally, each area of the inner padding 100 may comprise different patterns of holes 102, 104 such that a hole density of the inner padding 100 is varied across the inner padding 100. Hole density refers to the percentage of the surface area without mattress material, in other words the percentage of the surface area which is made up of gaps. The hole density is therefore a fraction of the surface area of the padded sheet, the fraction being a product of the average area of each of the holes and the distribution density of the holes across the inner padding 100, divided by the total area of the inner padding 100. Where the padded sheet is arranged to be configured in a plurality of modes, the areas of the padded sheet may be arranged according to deformation of said areas when transitioning between modes. For example, the padded sheet may be arranged in a first part of the inner padding where a relatively large amount of deformation is expected and a second area of a padded sheet may be arranged in a second part of the inner padding where a relatively small amount of deformation is expected (e.g. a large amount of deformation may be expected in a central portion of the padded sheet where an infant is placed, and a small amount of deformation may be expected at a distal portion of the padded sheet where the infants feet may rest in use). In some embodiments, holes 102, 104 having a larger width may be positioned in an area of the inner padding 100 which deforms when transitioning between different modes in use in an infant seat of the padded sheet 100 and holes 102, 104 having a smaller width may be positioned in area of the padded sheet 100 which does not deform, or deforms to a lesser extent than areas of the inner padding 100 having holes 102, 104 which have a larger width, when transitioning between different modes of the padded sheet 100 in use in an infant seat. For example, the deformation of an area when transitioning between modes may increase with increased width of holes 102, 104 in said area.

[0037] Alternatively or additionally, the inner padding 100 comprises holes 102, 104 of a plurality of shapes, the holes 102, 104 may be positioned based on their shape. The plurality of holes 102, 104 may be circular, alternatively the plurality of holes 102, 104 may be square, triangular, pentagonal, hexagonal, oval or any other shape. The array may also comprise holes 102, 104 of a plurality of shapes. The holes 102, 104 may be defined by at least one edge 106 surrounding a gap 108 or a void in the inner padding 100. The holes 102, 104 may extend through a thickness of the inner padding 100 such that the holes 102, 104 extend from an upper surface of the padded sheet to a lower surface of the inner padding 100.

[0038] The shape of the hole 102, 104 may be dependent on the location of the hole 102, 104 in the array. In some embodiments, holes 102, 104 having a shape which is more susceptible to deformation or expansion may be located in the centre of the inner padding 100 and holes 102, 104 having a shape which is less susceptible to deformation or expansion may be located proximate to an outer perimeter 110 of the inner padding 100. For example, the holes 102,104 which are located in the centre of the inner padding 100 may be square and the holes 102, 104 which are located proximate to an outer perimeter 110 of the inner padding 100 may be triangular. In some embodiments, holes 102, 104 having a shape which is more susceptible to deformation or expansion may be positioned in area of the inner padding 100 which deforms when transitioning between different modes of the inner padding 100 and holes 102, 104 having a shape which is less susceptible to deformation or expansion may be positioned in an area of the inner padding 100 which does not deform, or deforms to a lesser degree, when transitioning between different modes of the inner padding 100.The array may comprise a first hole 102 having a first width and second hole 104 having a second width. The first and second widths may be different. For example the first hole 102 may have a larger first width and the second hole 104 may have a smaller second width. The first width may for example be between 20% and 100% larger than the second width. The array may comprise holes of a plurality of widths. The array may comprise a plurality of holes 102 of the first width and a plurality of holes 104 of the second width. The array may also comprise a plurality of holes 102, 104 having a third or fourth width. The third width may be smaller than the second width and the fourth width may be smaller than the third width. The holes 102, 104 may be distributed across the inner padding 100 according to their width. For example holes 102, 104 of the first width may be positioned in the centre of the inner padding 100 and holes 102, 104 of the fourth width may be posited approximate to a perimeter 110 of the inner padding 100. The holes 102, 104 of the second width may be positioned between the holes 102, 104 of the first width and the holes 102, 104 of the fourth width. The holes 102, 104 of the third width may be positioned between the holes 102, 104 of the second width and tholes 102, 104 of the fourth width.

[0039] The holes 102, 104 may be positioned such that the width of the holes 102, 104 decreases radially from the centre of the inner padding 100 to the perimeter 110 of the mattress. Alternatively, the holes 102, 104 may be arranged according to deformation between states of the inner padding 100 such that the areas of the inner padding 100 comprising holes 102, 104 of the first width may deform to a greater extent than holes 102, 104 of the second, third and fourths widths when transitioning between states of the inner padding 100. Similarly, areas of the inner padding 100 comprising holes 102, 104 of the second width may deform to a greater extent than the holes 102, 104 of the third and fourth widths. Areas of the inner padding 100 comprising holes 102, 104 of the third width may deform to a greater extent than holes 102, 104 of the fourth width.

[0040] The first hole 102 having the first width may be adjacent in the array to the second hole 104 having the second width. The first hole 102 may refer to any hole with a width greater than the width of the second hole 104, the second hole 104 may refer to any hole with a width less than the width of the first hole 102. The array of holes may be arranged such that the plurality of holes 102 having the first width are adjacent to one another. For example, the array of holes 102, 104 may comprise an area of holes 102 having the first width. The array of holes may alternatively or additionally comprise an area of holes 104 having the second width. Both areas of holes 102, 104 may be adjacent to one another such that at the border of the areas, holes 102 of the first width are adjacent to holes 104 of the second width. Alternatively holes 102 having the first width may be arranged in a row 103 or column 105 or form a loop in the inner padding 100.

[0041] In some embodiments, the array of holes is arranged such that the width of holes 102, 104 within the array decreases with increased proximity to a perimeter 110 of the inner padding 100. The array of holes may be arranged such that a central area of the inner padding 100 comprises holes 102 of the first width and a border of the inner padding 100, surrounding the central area, comprises holes 104 of the second width.

[0042] In some embodiments, the array of holes may comprise several areas wherein each area comprises a plurality of holes 102, 104 of a single width. Alternatively, some embodiments maycomprise a plurality of holes 102, 104 of the same width. In such an embodiment, the hole density of the inner padding 100 may vary across the surface of the padded sheet. In said embodiment, the hole density the inner padding 100 may be greater at a central portion of the inner padding 100, and lesser at an area proximate to the perimeter 110 of the inner padding 100.

[0043] The widths of the holes 102, 104 of the array may, optionally be between 3mm and 15mm. The first width may, for example, be 10mm, and the second width may, for example, be 3mm. Where the plurality of holes 102, 104 are circular, the width of the individual holes 102, 104 may be the diameter of the holes 102, 104. In embodiments wherein the plurality of holes 102, 104 are square, the width of the holes 102, 104 is the shortest distance from one side of the hole to an opposite side of the hole.

[0044] As shown in Figure 1, the holes of the array may be arranged in rows 103 and columns 105. The columns 105 may be parallel with the edge 116 of the inner padding 100. Alternatively, the rows 103 and columns 105 may be at an angle relative to the edge 116 of the inner padding 100, as shown in Figure 1. The edge 116 may be a long edge of the inner padding 100. For example, the columns 105 may be at a 45 degree angle relative to the edge 116 of the inner padding 100. The angle may, for example, be between 5 and 85 degrees relative to the edge 116. In some embodiments, the distance between the centres of adjacent holes 102, 104 of at least one of the columns 105 is consistent in at least one direction.

[0045] Figure 2 illustrates a inner padding 100 according to an embodiment of the disclosure. The inner padding 100 may extend in a first direction 101. The first direction 101 may be the longitudinal direction of the inner padding 100. As shown in Figure 2, The array of holes may be arranged such that the width of the holes 102, 104 varies along said direction 101. For example, a first half 112 of the inner padding 100 may comprise holes 102 of the first width and a second half 114 of the inner padding 100 may comprise holes 104 of the second width. By way of further example, the inner padding 100 may comprise holes 102, 104 of a plurality of widths, for example three or four widths, which increase or decrease in direction 101. Turning again to Figure 1, in further embodiments, the holes 102, 104 of the array are arranged such that the distance between centres of adjacent holes 102, 104 varies in at least one direction. For example, the array of holes 102, 104 may comprise a plurality of columns 105, each column 105 having a plurality of holes 102, 104. The distance 109 between adjacent holes may be greater between a hole 107 at an end of the column 105 and an adjacent hole 111 than the distance between other adjacent holes 102, 104 of the column 105. For example, a column 105 of holes 102, 104 may comprise a plurality of holes 102, 104 which are equally spaced within the column 105. Said column 105 may additionally comprise holes 107 at one, or both, ends of the column 105 which are spaced further away from the adjacent hole 111, than the equal spacing of the other holes 102, 104 of the column 105.

[0046] The array may comprise at least a first pair 123 of two adjacent holes 122, 124 and a second pair 127 of two adjacent holes 126, 128. A first distance 118 between the first pair 123 may be the shortest distance between the holes 122, 124 of the first pair 123. A second distance 120 between the second pair 127 may be the shortest distance between the holes 126, 128 of the second pair 127. The first distance 118 may be different to the second distance 120. As shownin Figure 1, the first distance 118 may be larger than the second distance 120. In some embodiments, the first pair 123 and the second pair 127 are arranged in a single row 103. In other embodiments, the first pair of two adjacent holes 122, 124 and the second pair of two adjacent holes 126, 128 are arranged in different rows 103.

[0047] For example, wherein the first pair 123 and the second pair 127 are arranged in the same row 103 the distance between adjacent holes 102, 104 of the row 103 will vary. In such an embodiment, the first pair 123 may be positioned in the centre of the inner padding 100 and the second pair 127 may be positioned proximate to the perimeter 110 of the inner padding 100 and further away from the centre of the inner padding 100. Said row 103 may comprise several pairs of adjacent holes 122, 124 separated by the first distance 118 and several pairs of adjacent holes 126, 128 separated by the second distance 120. The distance between adjacent holes within a row 103 may increase radially from the centre of the inner padding 100. By way of further example, where the first and second pair are arranged in different rows 103, the distance between adjacent holes 102, 104 in each row 103 may be the same. The array may comprise a first row 103 wherein the distance between adjacent holes in the first row is the first distance 118 and a second row 103 wherein the distance between adjacent holes in the second row is the second distance 120. The array may comprise a plurality of rows 103 wherein the distance between adjacent holes in the same row is the first distance 118 and additionally, or alternatively, may comprise a plurality of rows 103 wherein the distance between adjacent holes in the same row is the second distance 120.

[0048] The arrangements described above relating to rows 103 of the array may apply to columns 105 of the array. As such, the distance between holes 102, 104 may vary within columns 105, between columns 105, within rows 103 or between rows 103 or a combination thereof. In varying the distance between holes in different directions, the deformation of the padded sheet under loads can be controlled and altered at different points along a direction. For example, wherein a varying stiffness in the first direction is required, the size of the holes can be varied in the first direction.

[0049] In some embodiments, the width of the individual holes 122, 124 of the first pair 123 is different to the width of the individual holes 126, 128 of the second pair 127. Optionally, the width of the individuals holes 122, 124 of the first pair 123 is less than the width of the individual holes 126, 128 of the second pair 127.

[0050] In some embodiments, as shown in Figure 1, holes 104 of the second width are arranged proximate to the perimeter 110 of the inner padding 100, with holes 102 of the first width positioned further away from the perimeter 110 of the inner padding 100. In this way the perimeter 110 of the inner padding 100 may be stiffer than the interior of the inner padding 100 and an area of the inner padding 100 adjacent to the perimeter 110 may be more rigid than a central area of the inner padding 100. In this instance, rigid refers to a reluctance to change shape under load, such as when transitioning between modes of the inner padding 100. In some embodiments, a hole density proximate to the perimeter 110 of the inner padding 100 is larger than the hole density of a central section of the inner padding 100.In alternative embodiments, as shown in Figure 2, holes 104 of the second width may be positioned in a first half 114 of the array and holes 102 of the first width may be positioned in a second half 112 of the array. In such embodiments, the area of the inner padding 100 comprising the first half 114 may be more rigid than the area of the inner padding 100 comprising the second half 112. Wherein an infant is placed on the padded sheet, the infant may be supported in the seated position with the infant’s bottom supported by the first half 114 and their back supported by the second half 112 of the array.

[0051] In alternative embodiments, as shown in Figures 3 and 4 the inner padding 100 may comprise at least one slit 130. The inner padding 100 may extend in a first direction 101 and a second direction 217. The first direction 101 may be the longitudinal direction of the inner padding 100, and the second direction 217 may be the transverse direction of the inner padding 100. The first direction 101 may be perpendicular to the second direction 217. The inner padding 100 may comprise a plurality of slits 130. For example, the inner padding 100 may comprise 2, 3, 4 or 5 slits 130. Said slits 130 may, optionally, be parallel to one another. Said slits 130 may also be arranged such that said slits 130 are equally spaced apart in at least one direction. Wherein the inner padding 100 extends in the first direction 101, the at least one slit 130 may extend in a second direction 217, as shown in Figure 3 which is non-parallel to the first direction 101. In this context, a slit 130 implies a long narrow opening extending further in the second direction 217 than in a direction non-parallel to the second direction 217. The inner padding 100 may extend further in the first direction 101 than in the second direction 217. The slit 130 may extend across only a portion of the extension of the mattress in the second direction 217. The slit 130 may be positioned centrally in at least one direction of the inner padding 100. For example, the slit 130 may be positioned centrally along second direction 217 of the inner padding 100.

[0052] The at least one slit 130 may extend straight across the inner padding 100, alternatively the at least one slit 130 may extend curvedly across the inner padding 100. In such configurations, the at least one slit 130 may extend curvedly in a single direction of curvature. The at least one slit 130 may, optionally, be ‘V’ shaped. ‘V’ shaped refers to the slit 130 having a cross-section in the shape of a letter ‘V’. Said slit 130 may comprise two straight slits at an angle relative to one another, coming together at a single vertex. Alternatively, the slit 130 may comprise two curved slits at an angle relative to one another coming together at a single vertex. Each slit may have a first, distal, end and a second end wherein the second end of both slits comes together to form a vertex.

[0053] The at least one slit 130 may extend entirely through a thickness of the inner padding 100. The at least one slit 130 may be formed such that in at least one mode of the inner padding 100 the at least one slit 130 is closed. In this context, closed refers to opposite sides of the at least one slit 130 being in contact, and slit 130 does not form an opening through the thickness of the inner padding 100, as shown in Figure 3. In at least one other mode of the inner padding 100 the slit 130 may be open. In this context, open refers to a gap being present between opposites sides of the at least one slit 130, and slit 130 forms an opening through the thickness of the inner padding 100, as shown in Figure 4. A closed gap may be opened by the application of a force either in the first direction 101 or in a direction which is perpendicular to both the first 101 and second 217 directions. For example, where the inner padding 100 is parallel to the ground, a downwards or upwards force may open the gap. In a first mode the inner padding100 may, for example, be horizontal. In a second mode a first area 132 of the inner padding 100 may have a non-zero radius of curvature. Said area 132, may be adjacent to a second area 134 of the inner padding 100. Second area 134 may slope at a gradient from the first area 132 to the horizontal, as shown in FIG. 4. In the second mode, the inner padding 100 may be arranged to form a dished seat.

[0054] In some embodiments the inner padding 100 may comprise at least one slit 130 and an array of holes 102, 104 according to any of the embodiments described above.

[0055] The inner padding 100 may be encased in a fabric or mesh sleeve for use as a padded sheet in an infant soothing product such as a bouncer or bassinet, etc.

[0056] Figures 3 to 8b illustrate a mattress assembly 200 according to an embodiment of the present disclosure. The mattress assembly 200 may comprise a plurality of layers, for example three layers. The mattress assembly 200 may comprise a first layer 202, a second layer 204, and a third layer 206. The first layer 202 may comprise a mesh material. The second layer 204 may comprise a foam material. The mesh material of the first layer 202 may optionally be a high stretch textile material. The mattress assembly 200 may additionally comprise a zipper or other securing means such as hook and loop type fasteners or buttons, poppers, magnets, clips, buckles, or the like. Said zipper or securing means may be arranged to connect a perimeter of the mattress assembly 200 to a rigid body, for example a rigid hoop or lower support frame 302 as shown in Figure 10.

[0057] Said second layer 204 may be a inner padding 100 according to any of the embodiments described above. Where the second layer 204 is a inner padding comprising an array of holes 102, 104, said array of holes may extend through a single layer 202, 204, 206 of the mattress assembly 200. Alternatively said array of holes may extend through a plurality, and optionally all of the layers 202, 204, 206 of the mattress assembly 200.

[0058] Wherein the second layer 204 of the mattress assembly 200 is a inner padding comprising at least one slit 130, said slit 130 may extend through a single layer 202, 204, 206 of the mattress assembly 200. Alternatively said at least one slit 130 may extend through a plurality, and optionally all of the layers 202, 204, 206 of the mattress assembly 200.

[0059] The third layer 206 may comprise a fabric material, mattress or other resting surface. Said fabric material may be water resistant. Said fabric material may, additionally or alternatively, be a low friction material. The first 202 and second 204 layers may be thermally bonded to one another such that a lower surface of the first layer 202 is thermally bonded to an upper surface of the second layer 204. Additionally, the second layer 204 may be thermally bonded to the third layer 206 such that a lower surface of the second layer 204 is thermally bonded to an upper surface of the third layer 206. Alternatively or additionally, the layers 202, 204, 206 of the mattress assembly 200 may be stitched together.

[0060] Turning to Figure 5, the mattress assembly 200 may comprise at least one stitch 208. Said at least one stich 208 comprises a first termination 210, a second termination 212, and a body 214, as shown in Figure 6b. Said at least one stitch 208 may pass through at least one hole 102, 104 of the array, optionally such that each individual stich 208 passes through an individual hole 102, 104 of the array. The first termination 210 may be located on an uppersurface of the first layer 202 and the second termination 212 may be located on a lower surface of the third layer 206. The body 214 may be enclosed by the edge 106 of the at least one hole 102, 104 of the array. In arranging the at least one stitch 208 in such a way, the mattress assembly 200 is not required to comprise additional holes to specifically accommodate the stitch 208. Further, by arranging the at least one stitch 208 through individual holes 102, 104 of the array, the stitch 208 may avoid affecting the integrity of the material of the inner padding 100.

[0061] As shown in Figure 6b, the at least one stich 208 may be arranged such that the first 202 and third 206 layers are pulled towards one another within the at least one hole 102, 104 of the array. Wherein the mattress assembly 200 comprise a plurality of stitches 208 said stitches may be arranged according to a specific pattern, as shown in Figure 6a.

[0062] The mattress assembly 200 may comprise additional features, for example a slot 216. Said slot 216 may, for example, be arranged to accommodate a seat belt, restraints or harness. Said slot may extend through each layer 202, 204, 206 of the mattress assembly 200.

[0063] In some embodiments, wherein said additional features are positioned within the array of holes 102, 104, holes 104 which are adjacent, or in close proximity to, said additional features may be holes 104 of smaller width compared to at least one other hole 102 of the array. Alternatively, said holes 102, 104 which are adjacent or in close proximity to, said additional features may be arranged such that the hole density of an area surrounding the additional feature is less than at least one other area of the mattress assembly 200.

[0064] Figures 7a and 7b illustrates the mattress assembly 200 in a first configuration. In the first configuration, the mattress assembly 200 is substantially flat and does not have a concavity or curvature. In said configuration, when the mattress assembly 200 is laid horizontal to the ground, it may be arranged as a firm substantially flat sleep surface, optionally for an infant. Wherein the mattress assembly 200 is an embodiment of the present disclosure comprising a inner padding 100 comprising at least one slit 130, the slits 130 are closed in the first configuration, as illustrated by Figure 3. Figure 7b is a cross section of a mattress assembly 200 in the first configuration comprising a inner padding100 comprising an array of holes 102, 104.

[0065] Figures 8a and 8b illustrate the mattress assembly 200 in a second configuration. In the second configuration the mattress assembly 200 may be arranged as a dished seat, optionally for an infant. In the second configuration, at least a portion of the mattress assembly 200 extends away from the horizontal plane 802 of the first configuration. In the second configuration, as shown in FIG. 8b, the mattress assembly 200 may have a first portion 218 and a second portion 220 extend away from the horizontal plane of the first configuration. The first portion 218 of the mattress assembly 200 may have a non zero radius of curvature. Said radius of curvature may for example be between 50mm and 120mm. The second portion 220 of the mattress assembly 200 may comprise a gradient connecting the first portion 218 to the horizontal plane of the first configuration. The mattress assembly 200 may also comprise a third portion 222 which is in the same horizontal plane relative to the first 218 and second 220 portions in both the first configuration and the second configuration. In some embodiments, when in the second configuration the first portion 218 may form a curved ellipsoid or concavity.In some embodiments, wherein the inner padding 100 of the mattress assembly 200 comprises an array of holes 102, 104, the holes 102, 104 may expand or contract when moving between the first and second configurations. The holes 102 of the larger diameter may be positioned in the first area 132 of the mattress assembly 200 described above. The holes 104 of the smaller diameter may be positioned in the third portion 222 of the mattress assembly 200 described above. The holes may be positioned in the array such that in the second configuration the position of the holes 102 with the larger diameter corresponds with the first 218 and second portion 220 of the mattress assembly 200 and that the position of the holes 204 with the smaller diameter corresponds with the third portion 222 of the mattress assembly 200.

[0066] The mattress assembly 200 may also comprise a strap 224 connected to a surface of the mattress assembly. The strap 224 may, for example, be connected to the lower surface of the second layer 204 of the mattress assembly 200. Alternatively, the strap 224 may be connected to a lower surface of the third layer 206 of the mattress assembly 200. In some embodiments the strap 224 may be connected to the surface of the mattress assembly 200 via a patch 226. The patch 226 may be a plastic material, for example a thermoplastic polyurethane material. The patch 226 may be attached to the lower surface of the second layer 204 of the mattress assembly 200, alternatively the patch 226 may be integrally formed with the surface of the mattress assembly 200. The patch 226 may be attached to the surface of the mattress assembly 200 via thermal bonding. Alternatively, the patch 226 may be attached to the surface of the mattress assembly 200 via a loop and hook configuration. The strap 224, in some embodiments, may be a pull cord optionally attached to the patch 226 via a loop hole 228. The strap 224 may be arranged to modify the mattress assembly 200 between a plurality of configurations. Wherein the mattress assembly 200 is in the first configuration, the strap 224 may pulled such that the mattress assembly 200 is converted to the second configuration. For example, wherein the strap 224 is attached at the first area 218, applying a force which is non parallel to the plane of the mattress assembly 200 when in the first configuration may convert the mattress assembly 200 from the first configuration to the second configuration. Conversely, when the mattress assembly 200 is in the second configuration, applying a force towards the horizontal plane of the mattress assembly 200, optionally at the location of the strap 224, may convert the mattress assembly 200 to the first configuration.

[0067] Figures 9 to 13 illustrate a convertible bassinet 300. The convertible bassinet 300 may be used in combination with the inner padding 100 or mattress assembly 200 according to any of the embodiments or features described above. The mattress assembly 200 may connect to the convertible bassinet 300 via the zipper. The zipper may optionally connect a support hoop of the convertible bassinet 300 to the perimeter of the mattress assembly 200. The support hoop may be comprised by the lower support frame 302.

[0068] The convertible bassinet 300 comprises a lower support frame 302 rotatably coupled to a base 304 and a backboard 306 pivotably coupled to the lower support frame 302.

[0069] The convertible bassinet 300 is convertible between at least a first and a second mode. Figure 9 illustrates the convertible bassinet 300 in the first mode. As shown in Figure 9, in the first mode, the lower support frame 302 and backboard 306 are horizontal to the ground and horizontal with respect to the base 304, that is the lower support frame 302 and backboard 306 may be horizontal with respect to support of the base 304 on the ground. In said first mode, the convertible bassinet 300 may be suitable for use as a bassinet such as to safely house an,optionally, sleeping infant and to provide a firm, substantially flat sleep safe surface without any concavity or curvature. In the first mode of the bassinet 300, the mattress assembly 200 may be arranged in the first configuration as described above.

[0070] Figure 10 is a cross sectional view of the convertible bassinet 300 of figure 9. Wherein the mattress 320 comprises the mattress assembly 200 and the mattress pad 322, the mattress assembly 200 may be located on an upper surface of the mattress pad 322 such that the mattress pad is located between a lower surface of the mattress assembly 200 and an upper surface of the backboard 306.

[0071] Figure 11 illustrates the convertible bassinet 300 in the second mode. In the second mode, the lower support frame 302 is inclined with respect to the ground and to the base 304, and the backboard 306 is inclined with respect to the lower support frame 302. In the second mode, the backboard 306 may be inclined with respect to the ground and / or the base 304 by between 15 and 30 degrees, and optionally the angle of inclination may be approximately 20 degrees. In the second mode, the convertible bassinet 300 may be suitable for safely housing a newly born infant. In particular, in the second mode, the convertible bassinet may provide a dished seat for the infant. In the second mode the mattress assembly 200 may be arranged in the second configuration as described previously.

[0072] Figure 12 is a cross sectional view of the convertible bassinet 300 in the second mode.

[0073] The convertible bassinet 300 may also comprise an upper support frame 308 connected to the lower support frame 302, optionally via a linkage mechanism 310. In the first mode, the upper support frame 308 may be based relatively far apart from the lower support frame 302. As shown in Figure 11 , in the second mode, the upper support frame 308 may be spaced relatively close to the lower support frame 302. A sidewall material is not shown in the figures for clarity, but a sidewall material would be positioned between the upper support frame 308 and the lower support frame 302, so that the underlying mechanism does not present a risk to the user.

[0074] The base 304 may optionally comprise a cam surface 312, and the backboard 306 may comprise a cam follower 314 in contact with said cam surface 312. The cam surface 312 may be configured to pivot the backboard 306 relative to the lower support frame 302 in response to movement of the lower support frame 302 between the horizontal position, relative to the base 304, of the first mode and the inclined position, relative to the base 304, of the second mode. The cam surface 312 may define a path, optionally comprising a detent 316 at one or both ends of said guide path. In the second mode the convertible bassinet 300 may be suitable for a bouncer for a newborn infant aged 0 to 3 months.

[0075] Figure 13 illustrates the convertible bassinet 300 in a third mode. In the third mode the convertible bassinet 300 may be suitable for a bouncer for a young infant of 3 months and older. In the third mode, the backboard 306 may be inclined with respect to the ground and / or the base by between 30 and 60 degrees, and optionally the angle of inclination may be approximately 45 degrees.

[0076] Figure 14 is a cross sectional view of the convertible bassinet of Figure 13.In some embodiments, the convertible bassinet 300 may comprise a handle 318 coupled to the linkage mechanism 310 such that the application of a force to the handle 318 effects movement of the lower support frame 302 from the horizontal position to the inclined position or movement of the lower support frame 302 from the inclined position to the horizontal. The handle 318 may be arranged to convert the convertible bassinet 300 between the first and second modes, and vice versa.

[0077] The backboard 306 of the convertible bassinet 300 may be configured to support a mattress 320. Said mattress 320 may comprise the mattress assembly 200 of any embodiments described above. The mattress 320 may comprise a mattress pad 322. The mattress 320 may be removably attached to one or both of the lower support frame 302 and the backboard 306. Alternatively, the mattress 320 may be fixedly attached to one or both of the lower support frame 302 and the backboard 306. In some embodiments, when the convertible bassinet 300 is in the first mode, the backboard 306 may be configured to support substantially the whole of the mattress 320 and when the convertible bassinet 300 is in the second mode, the backboard 306 may be configured to not support substantially the whole of the mattress 320. Where the backboard 306 is not supporting the whole of the mattress 320, the mattress 320 may be supported by its connection with the lower support frame 302 and from the inherent material stiffness of the mattress 320.

[0078] The convertible bassinet 300 may comprise a cavity 324 between the mattress 320 and the backboard 306 such that the mattress 320 is configured to extend in to the cavity 324 when the backboard 306 is inclined with respect to the lower support frame 302.

[0079] The convertible bassinet 300 may also comprise a lockout. Said lockout may be configured to maintain the convertible bassinet in the first mode. The lockout may additionally or alternatively, be configured to maintain the convertible bassinet in the second mode. The lockout may optionally be actuated by an actuator. Said actuator may be arranged to release and / or maintain the convertible bassinet in the first mode and / or the second mode. Wherein the bassinet comprises a handle 318, said handle 318 may comprise the actuator.

[0080] The convertible bassinet 300 may be arranged in the first mode, wherein in the first mode the upper support frame 308, the mattress 320 and the lower support frame 302 may be horizontal to the ground and with respect to one another.

[0081] The convertible bassinet 300 may be converted from the first mode to the second mode, and vice versa. As shown in Figure 11, the linkage mechanism 310 collapses between the first and second modes, bringing the upper support frame 308 towards the lower support frame 302. In the second mode the upper support frame 308 is at an angle relative to the lower support frame 302. As shown in Figure 12, the strap 224 of the mattress assembly 200 may be connected at one end to the backboard 306. In the second mode, the backboard 306 and mattress pad 322 may separate to form a cavity 324.

[0082] A user of the bassinet 300 may convert the bassinet from the first mode to the second mode using the mechanisms described above. The user may, optionally, use a handle 318 to collapse the linkage mechanism 310. The user may also exert downward pressure on the upper support frame 308, optionally in combination with the handle 318 to bring the upper support frame 308 and the lower support frame 302 together. The user may tilt the lowersupport frame 302 towards them. In doing so, the inner padding 100 may deform to form a dished seat such that an infant may be placed in the bassinet 300 and supported in a seating position. The user may place the infant in the bassinet 300 and optionally, fasten a harness to secure the infant to the bassinet 300.

[0083] The user of the bassinet 300 may convert the bassinet from the second mode to the first mode using the mechanism described above. The user may, adjust the lower support frame 302 to the horizontal position. In doing so, the inner padding 100 may return to a planar shape such that the infant may be placed in the bassinet 300 lying down, or in a horizontal position. The user may also, optionally via the handle 318, bring the upper support frame 302 away from the lower support frame such that the linkage mechanism 310 is in an extended configuration. The user of the bassinet 300 may remove the mattress 320 from the bassinet 300 by unzipping the zipper connection between the mattress and the support hoop of the lower support frame 302. The user of the bassinet 300 may install the mattress 320 in the bassinet 300 by zipping the zipper connection between the mattress 320 and the support hoop of the lower support frame 302. Similarly, the user of the bassinet 300 may remove the mattress 320 from the bassinet 300 by unzipping the zipper connection. The user of the bassinet 300 is therefore able to wash the mattress and re-install in the bassinet 300. Alternatively, the user of the bassinet 300 may replace the mattress with a replacement mattress with a different configuration. For example, the user may select a mattress with other desired properties or a different stiffness appropriate for their use (e.g. for a different weight infant), or the user may simply provide a replacement mattress of the same properties.

[0084] In the second mode a first section 305 of the backboard 306 and a first section 321 of the mattress pad 322 may be at a first angle relative to the base 304. In the second mode a second section 307 of the backboard 306 and a second section 323 of the mattress pad 322 may be at a second angle relative to the base 304, and at a third angle relative to the first section 305 of the backboard 306 and the first section 321 of the mattress pad 322. Wherein the strap of 224 of the mattress assembly 200 is attached to at least one of the second section 307 of the backboard 306 or the second section 323 of the mattress pad 322, in transitioning between the first and second mode the mattress assembly 200 is pulled in a direction non parallel to the first section of 321 of the mattress pad 322 such that the mattress assembly 200 is converted from a first mode to a second mode. As shown in Figure 12, in the second mode the mattress assembly 200 is configured in the second configuration as described above.

[0085] The convertible bassinet 300 may be converted from the first mode or second mode to the third mode, and vice versa. As shown in Figure 13, the linkage mechanism 304 is fully collapsed in the third mode, bringing the upper support frame 308 closer to the lower support frame 302 than in either the first or second modes. In the third mode the upper support frame 308 and the lower support frame 302 are approximately parallel to one another. In the third mode, the convertible bassinet 300 may be arranged to support a young infant in a more upright position than in either of the first and second modes and may be arranged to be used as a bouncer. In the third mode, the convertible bassinet 300 may be inclined upwards relative to the ground at an angle larger than in the second mode. As shown in Figure 14, in the third mode the mattress assembly 200 is configured in the second configuration as described above.The user of the bassinet 300 may convert the bassinet to the third mode by causing the linkage mechanism 304 to be operated, optionally via the handle 318. The user may exert pressure on the upper support frame 308 to bring it into contact with the lower support frame 302. In third mode, the user may place the infant in the bassinet 300. The user may, optionally, use the seat belt to secure the infant in the bassinet 300. In the third mode the bassinet may be used as a bouncer.

[0086] In such a way, a convertible bassinet 300, and methods for use are provided. The convertible bassinet 300 provides a single bassinet 300 which may be converted between a sleeping apparatus, such as in the first mode, a seating apparatus or newborn bouncer, such as in the second mode, or a bouncer such as in the third mode.

[0087] Figure 15 shows a schematic of a padded sheet 400 according to a further embodiment of the present disclosure. Padded sheet 400 may be implemented in the convertible bassinet as described herein with reference to Figures 9 to 14. Padded sheet 400 may be implemented in other bassinets or seats as the skilled person will appreciate. Various features and advantages of the padded sheet 400 will become apparent to the skilled person in light of the present disclosure.

[0088] Padded sheet 400 is shown in Figure 15 in an exploded view, comprising a inner padding 410, a top layer 420, and a bottom layer 430. The top layer 420 is disposed on a top surface 412 of the inner padding 410 and may be affixed thereon. The bottom layer 430 is disposed on a bottom surface of the inner padding 410 and may be affixed thereon. The top and bottom layer are preferably at the least attached at the perimeter to avoid the inner moving independently. Attachment may be by heat, pressure or spray adhesives, ultrasonic, impulse or RF welding, preferably sewing at the perimeter. The top layer 420 and the bottom layer 430 together encapsulate the inner padding 410. The top layer 420 and / or the bottom layer 430 may be formed from materials which provide waterproof, liquid proof, or antimicrobial properties. In this way the top layer 420 and the bottom layer 430 provide a barrier to the inner padding 410 from liquids or other soiling which may occur in use. The inner padding 410 may be formed from a foam or a spongy material providing cushioning for the padded sheet 400. The inner padding 410 and the top layer 420, and / or the bottom layer 430 are formed from breathable materials such that they do not suffocate and they provide some air flow to any objects in contact with the padded sheet 400.

[0089] The inner padding 410 includes a plurality of holes 440 extending at least partially through a thickness of the inner padding 410. The inner padding 410 may be cut from pre-slit foam sheets, both to form the perimeter shape, and then to create the holes 440. When in unstressed / unstretched condition, the holes 440 may be present and may be circular or ovalised. Naturally ovalised holes may not be detrimental, and may in some cases be preferable to give preferential reduction in stiffness / elasticity in a given direction, but circular is preferred. The circular nature (over, say a square or triangle), may reduce stress points that would arise from shapes with apexes or corners, and lead to tear propagation of the foam. The plurality of holes 440 may adjust the physical properties of the padded sheet 410. For example, the plurality of holes 440 may increase the breathability or the airflow of the padded sheet 400. The plurality of holes 440 increase the flexibility of the padded sheet 400. It will be appreciated that a comparable padded sheet without the plurality of holes 440 would have a material stiffness and a structural stiffness associated with the material choice and the size / shape ofthe padded sheet. The plurality of holes 440 in the inner padding 410 provide a reduction in stiffness of the padded sheet 400 relative to a padded sheet without the plurality of holes 440 by reducing the amount of material of the inner padding 410 contributing to the overall stiffness of the padded sheet 400. It will be appreciated that the size and shape of the plurality of holes 440 affects the stiffness of the padded sheet 400.

[0090] The arrangement of the plurality of holes 440 may be controlled such that the padded sheet 400 has desired stiffness characteristics. In the embodiment shown in Figure 15, the plurality of holes 440 are arranged in a plurality of rows 450. The rows 450 extend transversely T across the padded sheet 400. The transverse T direction may be defined as the direction across the padded sheet 400 having the minor axis or the shortest length across the padded sheet 400. Conversely, the longitudinal L direction may be defined as the direction across the padded sheet 400 having the major axis or the longest length across the padded sheet 400. It will be appreciated that such axes and lengths of the mattress are described to allow the skilled person to understand the present disclosure, but that variations of mattress shapes and sizes exist which appreciably have a longitudinal direction and a transverse direction with respect to their use. For example, in use, it would be expected that an infant be laid head to toe in a longitudinal direction of the mattress having left and right sides extending across the transverse direction of the mattress.

[0091] The plurality of rows 450 may be disposed at regular intervals along the longitudinal direction L of the padded sheet 400. Alternatively, the plurality of rows 450 may be spaced at various spacing distances according to a desired stiffness along the longitudinal direction. The plurality of rows 450 may be spaced in a longitudinal direction along the inner padding so that, between adjacent rows, a path may be drawn in a transverse direction which does not intersect with any holes 440 of the plurality of holes 440. The holes 440 within one row 450 of the inner padding 410 are offset from the holes of an adjacent row 450 in a transverse direction. Each row 450 of the plurality of rows may be transversely offset from each adjacent row 450 such that the holes 440 in each row 450 do not align with the holes 440 in adjacent rows as viewed from a longitudinal direction L. In an area of the inner padding comprising the holes 440, the material of the inner padding may follow a zig-zag path in the longitudinal direction; the holes 440 in each row 450 may not align with, but may overlap with, holes 440 in an adjacent row 450 as viewed from a longitudinal direction L such that there is no straight longitudinal path in the area comprising the holes 440 which does not intersect at least one of the plurality of holes 440. By offsetting the holes in a zig-zag pattern as described, coverage may be maximised, whilst also maximising the volume of foam between the holes as a means of balancing strength with extension I stretch.

[0092] By staggering or offsetting the holes 440 in each row 450 relative to adjacent rows, the stiffness of the padded sheet 400 may be reduced in a longitudinal direction L while maintaining a greater stiffness in other directions. Considering the stiffness of the padded sheet 400 in the longitudinal direction L, a path P may be drawn amongst the plurality of holes 440 indicating the centroid of the inner padding 410. In order to stretch in the longitudinal direction L, the material of the inner padding 410 extending longitudinally between holes 440 may extend and the material of the inner padding 410 extending transversely to create a zig-zag pattern may flex like a cantilever. Such flexing of the material of the inner padding 410 and the increased path length of the path P provide a relatively flexible mattress assembly in the longitudinal direction L. In other directions, the padded sheet 400 may be relatively stiff. For example,taking a path Q at an angle intersecting the longitudinal direction L and the transverse direction T, a straight path Q may be drawn which does not intersect with any holes 440 of the plurality of holes 440. Therefore, along the path Q, the stiffness of the inner padding 410 is not as significantly reduced relative to the longitudinal direction. Thus, the padded sheet 400 may be tuned to be more flexible in the longitudinal direction than in other directions. By providing a mattress assembly which is more flexible in the longitudinal direction, the padded sheet 400 may better conform to an out of plane extension of the padded sheet 400. To put it another way, the padded sheet 400 may flex more readily into a concave or bulbous shape as required by the convertible bassinet described herein. Whilst it may be achievable to provide a mattress assembly having a low overall stiffness to conform to a concave shape, such a material may be unable to maintain a substantially flat surface without wrinkles or disturbances when required, and may be unable to maintain suitable thickness under compression from the weight of an occupant.

[0093] Optionally, the padded sheet 400 may include a first reinforcing patch 460. Figure 16 shows the padded sheet 400 of Figure 15 further exploded to depict the structure of the assembly 400 and the reinforcing patches. The first reinforcing patch is disposed between the top layer 420 and the inner padding 410. A corresponding second reinforcing patch 470 is disposed beneath the bottom layer 430. The first reinforcing patch 460 and the second reinforcing patch 470 are held together by attachment means. The attachment means may be stitching the first reinforcing patch 460 and the second reinforcing patch 470 together through the inner padding 410. The reinforcement means may be any suitable mechanical attachment between the first reinforcing patch 460 and the second reinforcing patch 470. For example, the first reinforcing patch 460 and the second reinforcing patch 470 may be thermally welded, or adhesively coupled through the inner padding 410 and the bottom layer 430. The first reinforcing patch 460 and the second reinforcing patch 470 together reinforce the padded sheet 400 and allow the padded sheet 400 to be effectively manipulated into different shapes via the second reinforcing patch 470. The first reinforcing patch 460 and the second reinforcing patch 470 may reinforce the mattress, or alternatively the reinforcing patches may provide mechanical attachment without reinforcement of the layer. That is, the reinforcing patches may be flexible, durable, or they may be less flexible or durable than the padded sheet 400. The second reinforcing patch 470 may be secured to part of a convertible bassinet, such as the bassinet described herein, or an adjustable seat such that pulling the second reinforcing patch 470 may create a concave space above the padded sheet 400. The first reinforcing patch 460 may be located above the top layer 420 and secured through the top layer 420 as well to draw the top layer 420 into a concave shape. However, in the example shown in Figures 15 and 16, instead, a stitched portion 480 passes through the top layer 420 and the first reinforcing patch 460 to link the top layer 420 and the inner padding 410 together. In either case, the top layer 420 may conform to the shape of the rest of the padded sheet 400 beneath it.

[0094] It will be appreciated that the padded sheet 400 may be combined with the convertible bassinet described herein. According to a further embodiment of the present disclosure show in in Figure 17, the mattress assembly 200 may comprise a plurality of layers, for example three layers.
