An apparatus and method are provided for a sofa seat cushion comprising a cushion core including a multiplicity of pocketed springs enclosed within an upholstery foam envelope. The pocketed springs are positioned side by side in a spring layer arrangement and are independently operable. A memory foam layer positioned above the upholstery foam envelope comprises a material capable of molding to a person's body sitting on the sofa seat cushion and then quickly returning to an original shape once the person leaves the sofa seat cushion. The memory foam layer comprises a gel-infused visco-elastic memory foam with a polyethylene terephthalate layer positioned there above. Directly below the upholstery foam envelope is an upholstery-grade polyurethane foam layer with a polyethylene terephthalate layer positioned directly thereunder. An exterior upholstery surrounding the cushion core provides a plush seating surface.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

An inclined pocketed spring string (4) and a pocketed spring bed core (3). The inclined pocketed spring string (4) comprises a plurality of pocketed individual springs (1) connected at intervals. Each pocketed individual spring (1) comprises a fabric (11) and an individual spring (12) packaged in the fabric (11). The individual springs (12) in the pocketed spring string (4) are entirely or partially inclined in the fabrics (11) in an inclined manner. The inclined pocketed spring string (4) and the pocketed spring bed core (3) of the present invention, as compared with the pocketed spring bed core of the same size, can effectively decrease the number of springs used and reduce manufacturing costs.

Disclosed a reversible mattress comprising a layer of coil pockets comprising first and second coil pockets. Each of the first and second coil pockets comprise a coil spring disposed in a pocket. The mattress further comprises a first layer of cushion members comprising first and second cushion members engaged with an attachment member. The attachment member is engaged with the layer of coil pockets such that the first and second cushion members act directly upon the first and second coil pockets, respectively. The mattress further comprises a second layer of cushion members comprising first and second cushion members engaged with an attachment member. The attachment member is engaged with said second layer of coil pockets such that said first and second cushion members act directly upon said first and second coil pockets, respectively.

A support structure and vertical isolation structure may include a plurality of spring coils and a mesh network. Each spring coil of the plurality of spring coils includes a spring, a cap, and a floating connector. The cap is configured to engage the spring. The floating connector is disposed in a middle of the spring. The mesh network secures a first spring coil of the plurality of spring coils to a second spring coil of the plurality of spring coils by passing through the floating connector of each of the first spring coil and the second spring coil.

An adjustable sleeping system. At least some of the example embodiments are an adjustable sleeping system comprising a plurality of spring modules arranged in a first column, each spring module defines a row within the first column. Each spring module may comprise a rail and a plurality of adjustable spring assembles coupled along the rail. Each adjustable spring assembly may comprise a motor coupled to the rail, a lead screw coupled to a rotor of the motor, a spring plate coupled to the lead screw, and a spring coupled to the spring plate. A bed controller is communicatively coupled to each spring module, and the bed controller is configured to selectively control a load carried by each spring assembly.

Spring modules for an adjustable sleeping system. At least some of the example embodiments are spring modules comprising: a spring rail, and a plurality of adjustable spring assemblies spaced along the length of the spring rail. Each adjustable spring assembly may comprise: a motor with a stator coupled to the spring rail, a lead screw coupled to the rotor of the motor, and the lead screw extending above an upper surface of the spring rail, a spring plate coupled to the lead screw, and a main spring coupled to the spring plate. Thus, the weight or force carried by each adjustable spring assembly along the spring rail is separately adjustable by a bed controller.

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.
