This disclosure addresses mattresses. In particular, a mattress that includes a plurality of layers. A foam core of the mattress is constructed to have selected characteristics of support and cushioning, the characteristics varying from zone to zone of the mattress. The foam core includes at least three zones; a first zone corresponding generally to an area that supports the head of a user, a second zone corresponding generally to an area that supports the torso of the user, and a third zone corresponding generally to an area that supports the legs and feet of the user. A top surface of the foam core is formed with a plurality of parallel transverse peaks.

A mattress assembly includes a chassis having top and bottom walls and first and second sidewalls that each extend from the top wall to the bottom wall. Inner surfaces of the walls and the sidewalls define an interior cavity. The top and bottom walls each include a first section that is connected to the first sidewall and a second section that is connected to the second sidewall such that the first sections are pivotable relative to the first sidewall and the second sections are pivotable relative to the second sidewall. The first section of the top wall is pivotable relative to the second section of the top wall and the first section of the bottom wall is pivotable relative to the second section of the bottom wall. A spring assembly is configured to be positioned within the interior cavity.

A wool mattress set includes a receiving mattress including a wool filling enclosed in a first envelope, combined with a base mattress comprising a foam filling enclosed in a second envelope. The wool filling of the receiving mattress includes a stack of one or more superposed wool mat layers, essentially devoid of wool flakes, and the receiving mattress is laid on the base mattress, the receiving mattress and the base mattress being independent and separable from each other. The foam filling of the base mattress, whose density is at least 35 kg/m.sup.3, can include in particular a material originating from foam recycling.

A convertible mattress includes a primary mattress component, an upper mattress component located adjacent to the primary mattress component, a top mattress layer located adjacent to the upper mattress component; the primary mattress component having a mattress length, a mattress width, and a mattress depth; wherein the primary mattress component forms a mattress notch extending into the mattress depth, the mattress notch extending at least a portion of the mattress length and structured and disposed for providing a hinged axis about which the primary mattress component may be folded; and wherein the hinged axis allows the convertible mattress to be folded at a selected angle with limited bunching or compression of the convertible mattress. The mattress notch may extend along all or a portion of the length or the width of the primary mattress component and provides a pivot axis about which the primary mattress component may be folded.

A bedding system includes a chassis having a bottom wall, opposite first and second side walls extending upwardly from the bottom wall and opposite first and second end walls extending upwardly from the bottom wall. The walls define a cavity. A coil pack is positioned in the cavity. The coil pack includes a plurality of springs. A first cover is positioned over the coil pack. The first cover is attached to the chassis by a first zipper. A comfort layer is positioned over the first cover. The comfort layer is attached to the chassis by a second zipper. A second cover is positioned over the comfort layer. The second cover is attached to the chassis by a third zipper. In some embodiments, kits and method of use are disclosed.

A modular mattress comprising a plurality of modules configured to be positioned adjacent to each other forming a unique body having a support surface for a user, and comprising a plurality of engagement elements configured to reversibly engage a first and a second module of said plurality of modules, for avoiding movement from a correct relative position. The plurality of modules comprises a group of modules providing respective through holes aligned and oriented along a first predetermined direction, said aligned through holes being arranged to form a passageway passing through said modules of each group. There is one connection element configured to be positioned within said passageway, each connection element being provided at opposite ends, with respective engagement elements for reversibly engaging with respective engagement elements of a first and a second end module positioned, respectively, at opposite sides of each group of modules.

The present invention is a bed, mattress, or passed surface adaptable for sleeping or lying in the face down positions, also known as prone position; the side position; or other desired resting position. The invention includes a main body, accessory pieces adaptable for the different positions, and an optional bed frame and headboard. The present invention can also be used for a supine or reclined sleeping position.

A polymeric material mixture comprising a fluorine-containing polymer, a siloxane polymer, and at least two polymer processing additives (PPA), wherein the at least two polymer processing additives have different chemistries. For example, there can be a flexible coextruded pipe for providing a protective housing for cables, fluids, sludge or solids, the pipe comprising a pair of telescopically related inner and outer layers, where said inner layer is lubricated with the polymeric material mixture.

A upholstered sofa covered by a form fitting upholstery sack where the upholstery sack incorporates a supportive material panel that has integrated support webbing into the material panel. The support webbing comprising a plurality of webbing straps. With the upholstery sack properly positioned on the back rest portion, the supportive material panel is positioned on the front of the back rest portion frame. The material panel with webbing is incorporated as a component of the upholstery sack where the upholstery sack is pre-formed to snugly fit over the back rest portion of a furniture frame. The back rest portion or the frame is inserted into the sack and the material panel with integrated webbing is attached to the frame. Once the material panel is positioned and fastened, the remaining components, for example, the back panels and side panels, of the upholstery sack are attached to the frame at the back rest portion. Due to the construction of the material panel with webbing, installation time is decreased when compared to the time required for conventional webbing and upholstery installations.

A modular sleep apparatus that enables customization of a conventional mattress. The modular sleep apparatus includes a customizable mattress pad casing having pockets into which various inserts can be placed. The more the number of pockets, the greater customization the mattress pad allows. The inserts themselves can be of varying thickness, firmness, and material. The inserts can also be placed directly over a conventional mattress and held in place with a fitted sheet. The inserts can also be placed directly into pockets or envelopes in the top layer of a mattress. The mattress pad casing can be pre-assembled with inserts.
