A spring core is provided that includes a plurality of coil springs having an upper portion and a lower portion that collectively define an interior cavity. The spring core further includes a continuous upper fabric layer that covers each coil spring and defines a recess in the interior cavity of each coil spring. A cushioning layer is positioned atop the continuous upper fabric layer and extends into the recess in the interior cavity of each coil spring. A mattress assembly is further provided that includes the spring core, an upper body supporting layer, and a lower foundation layer. Methods of producing a spring core are further provided.

A ventilated mattress includes a ventilation system with an air distribution layer and a gel cushioning layer over the air distribution layer. The air distribution layer may include channels in a surface thereof, while voids that extend through an entire thickness of the gel cushioning layer may include voids that communicate with the channels. As the ventilation system forces air into the air distribution layer, the air may flow through the channels, into and through the voids of the gel cushioning layer, and to a top of the ventilated mattress.

A padding system includes a first pocket assembly and a second pocket assembly. The first pocket assembly includes a first pocket, where the first pocket has a top and a bottom and defines a first cavity, and a first padding component, the first padding component being positioned in the first cavity. The second pocket assembly includes a second pocket, where the second pocket has a top and a bottom and defines a second cavity, and a second padding component, the second padding component being positioned in the first cavity. The padding system also includes a first transition portion attaching the first pocket assembly to the second pocket assembly, where the first pocket assembly and the second pocket assembly form a string array, and a second transition portion configured to attach the string array to a bedding substrate.

A spring core is provided that includes a plurality of coil springs having an upper portion and a lower portion that collectively define an interior cavity. The spring core further includes a continuous upper fabric layer that covers each coil spring and defines a recess in the interior cavity of each coil spring. A cushioning layer is positioned atop the continuous upper fabric layer and extends into the recess in the interior cavity of each coil spring. A mattress assembly is further provided that includes the spring core, an upper body supporting layer, and a lower foundation layer. Methods of producing a spring core are further provided.

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.

The invention relates to a mattress (1, 1′, 2, 3) having at least one first layer (10, 20, 30), a second layer (12, 22, 32) and a third layer (14, 24, 34), the second layer (12, 22, 32) comprising spring elements (16, 26, 36) and being interposed between the first layer (10, 20, 30) and the third layer (14, 24, 34). The thickness (a.sub.1, a.sub.2, a.sub.3, d.sub.1, d.sub.2, d.sub.3, . . . , d.sub.10) of the third layer (14, 24, 34) varies locally to an extent that exceeds the extent defined by a surface structure of the third layer (14, 24, 34) on its exterior surface (17).

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string comprises one piece of fabric joined to itself to create first and second opposed plies on opposite side of coil springs. The plies are joined by transverse seams to form a plurality of pockets along a length of the string. At least one spring is positioned in each of the pockets. The piece of fabric is a non-woven ultrasonically weldable fabric made with fiber made with at least some used or recycled material or content.

A mattress having a lightweight first foam layer including a top surface and a bottom surface, where the first foam layer is formed from a single piece of molded foam, and where the lightweight first foam layer is formed at least partly from melamine resin.

Mattress assemblies include a hybrid posture support system that provide an end user with improved posture support during use, among other advantages. The hybrid posture support system includes a top foam layer including first and second foam portions that are spaced apart and generally correspond to a head/shoulder region and a foot region, respectively, a pocketed microcoil array underlying the top foam layer that is intermediate the first and second foam portions; and an underlying foam layer. The hybrid posture support system can be used in any mattress assembly including mattresses having a coil spring innercore or a foam innercore.

Beds may include environmental control components, which may be temperature control components and pressure adjustment components in some embodiments. The environmental control components may be configured, for example by a controller, to provide different sleep environments based on identity of sleepers using or expected to use the bed. The controller may receive information as to how to configure the components based on one or more sleep profiles for sleepers expected to use the bed. The sleep profiles may be received from a server, or received from a smartphone of a sleeper. The sleep profiles may be deleted from the bed after use.
