The support characteristics within a foam mattress body may be varied by inserting reinforcements into channels cut or otherwise formed within the foam.

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 shaped body includes at least one spring and at least one foam section. An uppermost section of the foam section is attached to an uppermost section of the at least one spring and a lowest section of the foam section is attached to the lowest section of the at least one spring. The uppermost section is attached by affixation through a top plate to the at least one spring and the lowest section is attached by affixation through a bottom plate to the at least one spring. The at least one spring is arranged adjacent to the at least one foam section. The top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least one spring and the at least one foam section.

A beadstead has a circumferential main outer frame, a dimensionally stable support element attached or attachable to the main outer frame, a cover surrounding the main outer frame and the support element and having outer edges, a multipart and profiled circumferential retaining strip wrapped by the edges of the cover that are folded over and project beyond the retaining strip for fixation under the retaining strip. The retaining strip extend transversely to a plane of the support and having a first leg projecting parallel to the support, spaced from the plane, and extending below the support. Clips fastened to the outer edges of the cover fit on the first leg to secure the edges to the frame in a desired position.

Adjustable sleeping system with force control. At least one example embodiment is a method of operating a sleeping system, the method including: sensing an area of a sleeping surface of the sleeping system, the area upon which a person resides, the sensing by a bed controller communicatively coupled to an array of adjustable spring assemblies arranged such that a top of each adjustable spring assembly defines an upper surface parallel to the sleeping surface; and driving a plurality of the adjustable spring assemblies being the adjustable spring assemblies beneath the area, the driving to control force distribution among the plurality of the adjustable spring assemblies.
