Mattress assembly with convertible topper

a mattress and convertible technology, applied in the field of mattress assembly with convertible topper, can solve the problems of increasing the difficulty of placing the most comfort forming material (specifically, the fibrous material) in a permanently attached pillowtop, the sheer size and weight of the mattress, and the addition of a significant amount to the cost of the mattress

Problems solved by technology

There are certain design constraints on mattress innersprings, such as the gauge of wire of the coils, the diameter, height, and number of coils in the array.
Placing most of the comfort forming material (specifically, the fibrous materials) in a permanently attached pillowtop is made increasingly difficult by greater numbers of layers of material, and by the sheer size and weight of the mattress.
The approach also necessitates that equal numbers of compressible material layers be inclu...

Embodiment Construction

[0013]FIG. 1 shows a mattress assembly with convertible topper sleep system of the present invention 100, which includes a foundation unit 10, a support unit or innerspring 20, and a comfort unit or pillowtop 30. The foundation unit 10 can be of conventional internal design and construction, having a rectangular frame on which are mounted a plurality of spring elements or modules (not shown) to provide flexible support for an overlying grid (not shown) which defines the foundation surface 50. The spring module may be formed of wire or made of composite material. Alternatively, the foundation unit 10 can be made entirely of wooden materials. This design eliminates metal-to-metal contact, thus reducing noise and also provides a stronger, more durable bed foundation. The wooden foundation unit also provides high sway resistance and prevents uncomfortable sinking and sagging where weight is concentrated. The wooden unit also ensures longer life, making such foundation appropriate for hi...

Abstract

A convertible mattress including a foundation unit, a support unit and a comfort unit. The foundation unit includes several spring elements that provide flexible support for an overlying grid which defines the foundation surface. The foundation unit may be supported by a bed frame which may further include side boards, a head board and foot board. The comfort unit, or innerspring, is located atop the foundation unit and contains several interconnected spring coils or a foam core structure. The top and bottom surface of the comfort unit contain minimal covering to provide a smooth surface over the ends of the coils of the innerspring. The comfort unit is located atop the support unit and has a generally horizontal top and bottom and generally vertical sides extending between the top and bottom that defines a central space containing support and cushioning components such as foam. A series of Velcro™ straps are attached to the perimeter of the support unit that connect to Velcro™ target straps located along the perimeter of the comfort unit. The straps secure the comfort unit to the support unit and enable quick and easy removal and replacement of the comfort unit. Different comfort units may contain different materials that have varying support characteristics. The comfort unit can be either one- or two-sided.

Description

RELATED APPLICATIONS[0001]There are no applications related to this application.FIELD OF THE INVENTION[0002]The present invention pertains generally to support structures for sleeping, and more specifically to adaptable support structures that can be easily replaced with alternate upper support layers containing different insert materials with varying support characteristics.BACKGROUND OF THE INVENTION[0003]Devices for supporting the human body while sleeping have evolved generally from pads, to pads in combination with or supported by springs such as the common mattress, and further in combination with stiffer springs such as in mattress foundations or box springs. In a conventional mattress, springs or coils are interconnected in a matrix array, and covered on each side with layers of padding and fabric. Much of the innovation in mattresses and box springs is in the area of spring design, seeking configurations which provide optimal support of the body, in combination with the pad...
