A baby sleeping cushion and method of use thereof, wherein the cushion is wedge-shaped and comprises two principal layers, a top layer and a bottom layer. The bottom high-density foam provides a firm backing or support and the selected elevation from head end to foot end. The viscoelastic or visio memory foam top layer molds to the body form of a baby, retarding lateral movement of the baby, and preventing the baby from rolling from side-to-side. In addition to the two-layer wedge-shaped cushion, a separate cushioning device, generally hemispherical in shape, is removably secured to the wedge-shaped cushion, and supports the baby's legs and buttocks; thereby preventing movement of the baby in response to the inclined slope of the wedge-shaped cushion. An additional embodiment provides a support pillow to restrain the baby's head from movement removably-secured to the wedge-shaped cushion.

A foam mattress in which a layer of latex or latex-like foam placed above a layer of memory foam is described. This construction of the mattress provides the contouring pressure relief that a visco-elastic foam provides with a top surface with quick recovery (a latex-like “bounce”) that prevents people from getting “stuck” in the visco-elastic foam and improves the springiness of the mattress. The mattress may also include straps and cinches to aid in transportation of the mattress. The mattress may also include removable covers that aid in keeping the mattress clean.

A glove that can be used as a conventional glove, or, alternatively, if the glove is to be used for special purposes, can be modified to include shaped articles comprising yieldably deformable, shaped-inserts of different configuration constructed from foamed cushion material having a memory. These shaped articles can be selectively inserted into strategically located, internal pockets formed internally and externally of the glove. When the shaped-inserts are in position within the pockets of the glove, they provide protection to the hand, provide superior tactile perception and also tend to substantially replicate the surface features exhibited by the device being gripped by the user.

An inflatable bed assembly having a plurality of inflatable cushion cells disposed on the top of the inflatable bed. Each cushion cell has a vent fluidly interconnecting the interior volume of the cushion cell with a main air chamber of the bed. When the bed is inflated, the cushion cells inflate and form raised projections on the top of the bed. The cushion cells provide a pressure sensitive surface which molds to the user's body for increased comfort. The vents are sized to allow the cushion cells to inflate upon inflation of the main air chamber, partially deflate when pressure is applied, and re-inflate when the pressure is removed. The size of the vents dampens the rate that air passes through the vent. The controlled inflation and deflation of the cells softens the impact caused by application of a body thereon and simulates the dampened response of “memory-foam”.

A screen assembly has a material that conforms to the borehole shape after insertion. The assembly comprises a compliant layer that takes the borehole shape on expansion. The outer layer is formed having holes to permit production flow. The selected conforming material swells with heat, and in one non-limiting embodiment comprises a shape memory foam that is thermoset or thermoplastic. Heat is provided by supplying a fuel (including an oxidant) to a catalyst in close proximity to the compliant layer so that the product from the catalytic reaction is heated steam which contacts and deploys the conforming material. The base pipe can have a screen over it to act as an underlayment for support of the conforming layer or alternatively for screening.

A cushion of a portable seat is formed from multiple layers including at least one memory foam layer.
