A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.

A mattress includes a base layer having a first surface and a second surface arranged opposite to the first surface. The base layer defines a plurality of slots extending from the first surface to the second surface and arranged in a plurality of rows in a staggered arrangement. The mattress also includes a plurality of hoop assemblies arranged inside the plurality of the slots. Each hoop assembly includes a hoop arranged vertically inside the slot and a central axis of the hoop extends substantially horizontally and parallel to the first surface. The hoop is configured to compress under a load.

The disclosed technology includes tiered void cells which provide protection, comfort, and stability during compression. The tiered void cells may be arranged in vertically stacked columns and include a stroke whereby tiers of a void cell can telescope into adjacent tiers of that void cell, as well as telescope into adjacent tiers of adjacent void cells in a column. Implementations described and claimed herein include a cushioning system comprising an array of tiered void cells, wherein each tiered void cell includes a base portion, a plunger portion, the plunger portion to collapse into the base portion under compression of the cushioning system, and a living hinge elastically connecting an inner perimeter of the base portion to an outer perimeter of the plunger portion.

A coil-in-coil spring is provided that exhibits a variable loading response as the spring is compressed. The coil-in-coil spring comprises a continuous wire forming’ an inner coil having a substantially conical shape and an outer coil extending around the inner coil and having a substantially cylindrical shape. The inner coil includes a plurality of helical convolutions with diameters that progressively decrease as the plurality of helical convolutions extend from a lower end of the coil-in-coil spring to an upper end convolution of the inner coil. The inner coil also has an uncompressed height that is about 75% of the uncompressed height of the outer coil, A mattress is further provided and includes the coil-in-coil springs arranged in a matrix.

A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular or rectangular weld seams. Regardless of the shape of the weld seams, the different firmness of the different sections of the comfort layer may be due to different mini coil springs contained in the pockets. All pockets may have the same spring, the springs may be contained in different size weld seams to create pockets of different heights.

A comfort layer for a bedding or seating product has fast-acting pockets characterized by the individual mini springs of the comfort layer being pocketed with permeable fabric having apertures therein. Apertures in the fabric facilitate airflow through the fabric. The permeable fabric is specifically structured to facilitate airflow while minimizing noise. Each seam joining opposed pieces of fabric around each of the mini coil springs of the comfort layer may be segmented, allowing air to flow between the segments.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

Embodiments of the invention relate to a cushion apparatus comprising a resilient spring member. Typically, the cushion apparatus in configured to provide flexible support to a user, allow air circulation through and within the cushion apparatus and allow ventilation of excess heat. In some embodiments, the cushion apparatus comprises a resilient spring member and a cushion cover member at least partially enclosing the spring member. In some embodiments, the cushion cover member is structured to be removable attached to the resilient spring member.
