An electric motor driven adjustable mattress has a shared casing in which at least one flat cushion element of a cushion structure and an electric motor driven adjustable support apparatus for supporting the cushion element are accommodated. The support apparatus has two support parts that are adjustable relative to one another, and that on their sides facing the cushion element are provided with spring elements for elastically resiliently supporting the cushion element. For adjusting the support parts relative to one another, an electric motor driven drive apparatus is accommodated in the shared casing.

Nonwovens having low-density and resilience have a chemical formulation applied on one surface (e.g., a top surface) by any of various application methods. Then, the chemical formulation is forced to move toward the opposite surface of the nonwoven (e.g., move downward through the nonwoven from top to bottom). The chemical-treated nonwoven is dried to fix the chemical on the nonwovens. Movement through the nonwoven is performed in a controlled fashion so that after drying the distribution of a chemical formulation throughout the nonwoven (e.g., from the top surface to the bottom surface of a nonwoven) is controlled.

A bed has a mattress with a mattress top, a mattress bottom, and a mattress perimeter. The mattress includes a mattress cover surrounding the mattress. The mattress cover includes a first stretch fabric around the mattress perimeter of the mattress. The first stretch fabric has a first predominant stretch direction that is stretchable in a direction parallel to the mattress top. A multidirectional stretch fabric is positioned on the mattress top.

A mattress topper is provided that includes a cover having opposing first and second panels each made from a first material. The mattress topper includes a gusset that either perimetrically joins the first and second panels and/or is in the form of one or more patches located on the first and/or second panels. The gusset is made from a second material that has a porosity that is different than that of the first material. A fill material is disposed within the cover.

A bed can include a mattress and a foot warming system. The mattress can include a mattress cover and a support structure that is positioned under and covered by the mattress cover. The foot warming system can include a heating unit an envelope, a power source, and an electrical connector electrically connecting the heating unit to the power source. The heating unit can be positioned inside the envelope between the envelope top and the envelope bottom. The heating unit and the envelope can be positioned at a foot of the bed under mattress cover between the support structure and the mattress cover.

A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

A self-inflating stowable bed. The bed includes one or more self-inflating chambers, with each of the self-inflating chambers having one or more polyurethane foam sections therein, with the chamber defined between a first air impervious layer and a second air impervious layer. The self-inflating bed may be evacuated by a household or shop vacuum, and then sealed, rolled or folded, and easily stored or shipped. The polyurethane foam sections may be provided with different members having different indentation force deflection specifications suitable for bed portions and edge of bed portions.

A waterbed system for placement on a ground surface can comprise one or more of the following components: a waterbed mattress, a foam structure around the periphery of the mattress, a platform below the mattress and the foam periphery for supporting the waterbed mattress and the foam structure, a foundation coupled to and extending downwardly from the platform, preferably a single, fire resistant polyester fiber baffle disposed within the waterbed mattress, a cover over the top surface of the mattress and around the outer surface of the foam structure, a water proof liner below the bottom surface of the mattress, a water bed heater under the liner between the liner and the upper surface of the platform, a layer of fiberglass insulation attached to the lower surface of the platform, and an accessory storage container coupled to the foundation.

A piezoelectric adaptive mesh includes multiple piezoelectric fibers that include piezoelectric structures that can act as sensor and/or actuators to enhance a person's comfort. The piezoelectric structures communicate with a controller and/or a software processing system and may identify the position of a user and make adjustments through the actuators to increase user comfort by providing support, assistance, treatment, and/or temperature adjustment.

A body support cushion, e.g., mattress, has multiple foam layers, including a viscoelastic foam layer and a reticulated foam layer, and an outer cover. At least one of the foam layers and the outer cover each includes phase change material having latent heat properties that provide two intervals of dermal cooling.
