A mattress assembly includes a base layer, a coil layer disposed over the base layer, an upper layer disposed over the coil layer, and an elastomeric cushioning element disposed over the upper layer. The coil layer may include a plurality of pocketed coils. Furthermore, the elastomeric cushioning element may have a thickness within a range of about 2.0 inches to about 4.5 inches. Furthermore, the elastomeric cushioning element may form between about 15.0% and about 32.0% of an overall thickness of the mattress assembly. A method of forming a mattress assembly includes disposing a coil layer over a base layer, disposing an upper layer over the coil layer, disposing an elastomeric cushioning element over the upper layer, and disposing an outer covering over at least the upper layer.

A composite mattress includes a pressurizable layer and a top layer. A coiled spring layer may also be included in the composite mattress. The composite mattress may also include a base layer and/or an intermediate layer. A foundation, or rail, may laterally surround the pressurizable layer and the top layer. The composite mattress may include a cover, including a base panel, a periphery, and a top panel. The cover may encase the other components of the composite mattress. The composite mattress may include a separable top and bottom; these elements may be modular, enabling individuals or couples customize a mattress by selecting one or more tops from a plurality of available for use with one or more bases from a plurality of available bases.

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.

Vertically lapped nonwoven material is used to provide enhanced breathability and comfort in mattresses by replacing foam material in one or more of, including all of top panel quilts, layers underneath the top panel quilts, and in side blocks which surround spring supports. The vertically lapped nonwoven may provide advantages in terms of cost, manufacturing ease, robustness in mattress design, while at the same time providing the user with a much more comfortable sleeping experience.

A composite mattress includes a base panel of a cover, a base layer, a pressurizable layer, an intermediate layer, a top layer, and a top panel of the cover. A foundation, or rail, laterally surrounds the pressurizable layer, the intermediate layer, and the top layer. A periphery of the cover laterally surrounds the foundation and, with the top panel and the base panel, encases the other components of the composite mattress. A coiled spring layer may also be included in the composite mattress. The composite mattress may include a separable top and bottom; these elements may be modular, enabling individuals or couples customize a mattress by selecting one or more tops from a plurality of available for use with one or more bases from a plurality of available bases.

A mattress having variable height and hardness is disclosed. The mattress comprises a base layer held by a mattress cover using an extendable attachment system. The mattress further comprises one or more top layers made of resilient material which are stacked on top of the base layer. Only friction between the material of the top layers limit the lateral or longitudinal movements of a layer with regard to another layer.

A mattress embodying a removable exterior top and interchangeable segments (e.g. foam) positioned above a mattress base support portion and below the removable exterior top. The removable exterior top may be replaced with new or different removable exterior tops. Also, users have the ability to vary softness (i.e., firmness) or other characteristics (e.g., foam component construct) across the mattress by arranging or rearranging the interchangeable segments located directly below the removable and interchangeable mattress top. An exemplary base support portion may include a heavy duty pocketed inner-coil unit for motion transfer support and increased airflow.

A mattress 10 that provides an edge support feature that remains firmly supportive throughout bending of the mattress on an adjustable foundation, while also providing a flat, tailored finish for the side of the mattress. The mattress has a base, an upper surface, and two side walls extending between two end walls such that the base, upper surface, side walls, and end walls define a cavity comprising a mattress support, such as a spring unit, that supports the upper surface above the base. The side walls and/or end walls comprise an edge support system having a plurality of overlapping edge segments.

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 mattress assembly includes a cover, a spring pack positioned within the cover, and an inner core positioned within the cover. The inner core includes opposite first and second portions. The first portion has a firmness that is different than a firmness of the second portion. The inner core is configured to be moved between a first configuration in which the first portion directly engages the spring pack and a second configuration in which the second portion directly engages the spring pack to alter a firmness of a sleep surface of the mattress. Methods of use are disclosed.
