Also disclosed are mattress assemblies including the removable top panel.

Abstract: A mattress assembly includes an inner core comprising a base core layer comprising planar top and bottom surfaces, and at least one comfort layer comprising planar top and bottom surfaces disposed on the top surface of the base core layer; a side rail assembly disposed about a perimeter of the inner core; and a plurality of air channels extending from a central region of the inner core to the side rail assembly configured to permit the flow of fluid from and to the inner core.

Abstract: Mattress and foundation assemblies generally include a mattress; and a mattress foundation for supporting the mattress, the mattress foundation including a frame configured to elevate the mattress relative to ground; and upper and lower flexible mesh suspension layers spaced apart from one another, each independently supported by a plurality of carriers at discrete points about the surface of the suspension layers, wherein the carriers are pivotably coupled to the frame.

Abstract: The mattress assemblies have an array of springs extending from a sheet. Each spring in the array may be manufactured by choosing a position for the spring, cutting a profile of the sheet spring in the sheet, peeling back or bending the profile or tab of the sheet, and shaping the profile to form the sheet spring. The array of springs may be formed from creating a plurality of such springs along rows and columns. In certain embodiments, multiple sheets may be stacked to form the sheet spring array.

Abstract: A thermally activated display with a temperature management feature and a cover comprising a thermochromic material generally changes from a first color to a second color. The temperature management feature can be a mattress and has a top surface. The cover is substantially flush with the top surface.

Abstract: A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit.

Abstract: Mattress assemblies that provide increased user comfort and increased airflow. The mattress assemblies generally include a multilayered mattress core including at least one coil spring layer disposed on and in direct contact with a viscoelastic foam layer.

Abstract: Mattress packaging displays and the display containers for displaying one or more mattresses in a retail environment generally include a bottom panel, a top panel, sidewalls extending from the bottom panel to the top panel, a front facing panel, and a rear facing panel; wherein the container is seated on the bottom panel during display and comprises at least one opening exposing at least a portion of the mattress, and wherein the container is configured to contain the mattress.

Abstract: A plunger matrix mattress includes a number of independently movable foam padded plungers that form an array of independently movable points of support. This type of mattress significantly improves body contouring over conventional coil spring mattress designs. The plunger matrix mattress also allows substantial airflow through the mattress improving over conventional foam mattress designs. Different plungers may have different spring and dampening characteristics to allow different plungers and plunger zones of the mattress to exhibit different firmness levels. Individual plungers may be removed and replaced independently, for example to replace the plunger with another plunger with a different spring characteristic, and make other types of adjustments and repairs.

Abstract: A foldable mattress includes plunger matrix sections and corresponding flexible connectors connecting the plunger matrix sections in side-by-side relation. The flexible connectors are configured to allow the foldable mattress to fold to adjust in shape corresponding to changes in shape of a mechanically adjustable frame supporting the foldable mattress. The foldable mattress may include a foldable edge frame configured to snugly receive and house the plunger matrix sections in side-to-side relation. The edge frame defines a flange on an internal surface of the edge frame configured to support the plunger matrix sections in side-to-side relation in a position allowing the plungers to move up and down within an internal space defined by the edge frame. A top pad lays on top of the edge frame and the plunger matrix sections. A cover encapsulates the edge frame, the plunger matrix, and the top pad into a self-contained mattress unit.

Abstract: A dual-spring plunger for a plunger matrix mattress assembly includes an outer tension spring with an upper end fixed to an outer spring mount of a plunger guide body and a lower end located below the guide body positioned to receive a bottom end of a pin of the plunger. An inner tension spring nested within the outer tension spring has an upper end fixed to the inner spring mount of the guide body and a lower end having a spur slidably captured within a slot through a fin of the shaft of the pin. The outer spring is tensioned while the inner spring is not tensioned during a first portion of downward movement of the pin relative to the pin guide, whereas both the outer and the inner spring are tensioned during a second portion of downward movement of the pin relative to the pin guide.

Abstract: A modular mattress includes several plunger matrix sections that each have a respective plunger matrix support platform. The several sections are configured for side-to-side assembly to form the complete matrix for the mattress. A foldable edge frame snugly receives and houses the plunger matrix sections in side-to-side relation. The edge frame also defines a flange on an internal surface of the edge frame that supports plunger matrix sections in side-to-side relation in a position allowing the plungers to move up and down within an internal space defined by the edge frame. A top pad lays on top of the edge frame and the plunger, while a cover configured encapsulates the edge frame, the plunger matrix, and the top pad into a self-contained mattress unit.

Abstract: A plunger for a matrix mattress includes a pin guide having a flange and a guide body extending from the flange. A pin slidably received within the pin guide includes a flange located above the flange of the pin guide and a shaft extending from the flange through the guide body. The flange of the pin carries a deformable head. A tension spring has a first end fixed to the guide body and a second end located below the guide body positioned to receive a bottom end of the pin shaft. The spring is configured to resiliently stretch with downward motion of the pin with respect to the pin guide. A dampening device captured around the shaft of the pin between the flange of the pin and the flange of the pin guide resiliently deforms with downward motion of the pin with respect to the pin guide.
