    摘要： A dual-spring plunger for a plunger matrix mattress assembly, comprising a pin guide comprising a flange, a guide body extending from the flange, an outer spring mount extending from the guide body, and an inner spring mount extending from the guide body wherein the outer and inner spring mounts are disposed in an axially tiered relation; a pin slidably received within the pin guide comprising a flange located above the flange of the pin guide, a shaft extending from the flange through the guide body, and an elongate slot through the shaft; an outer tension spring having an upper end fixed to the outer spring mount of the guide body and a lower end located below the guide body positioned to receive a bottom end of the pin shaft; an inner tension spring nested within the outer tension spring having an upper end fixed to the inner spring mount of the guide body and a lower end comprising a spur slidably captured within the slot through the shaft;
    wherein the outer tension spring is tensioned while the inner tension spring is not tensioned during a first portion of downward movement of the pin relative to the pin guide, and wherein both the outer and the inner tension springs are tensioned during a second portion of downward movement of the pin relative to the pin guide.

    摘要： A mattress assembly supporting a mattress and occupants is constructed substantially of plastic material. A mattress foundation (100, 200, 300, 400) defined by a semi-rigid cavity includes a generally flat top surface (110) and at least one sidewall (120, 220, 320) depending from the top surface. For pliability and structural weight reduction, the foundation may be ribbed, with air spaces formed therein. Ground support members (130, 140) may be used to retain the foundation in a substantially horizontal orientation above ground. To reinforce the foundation's structural integrity, support braces (230) connecting opposing sidewall portions may be used. The braces may be detachable or integrally formed with the foundation. The assembly may include a headboard (410). To ease transport, casters (310) may be included with the foundation. The assembly may be constructed of extruded or assembled plastic pieces; molded plastic; recyclable plastic; plastic reinforced with metal core, metal fiber, glass fiber, carbon fiber, resin or a combination of these.
