• Embodiments of the disclosure relate generally to mattress platforms constructed of metal and used to support a mattress cushion above the ground.
• Mattresses are commonly supported above ground using an assembly that includes a metal frame and a mattress foundation, which is commonly referred to in the industry as a "box spring” or a "box.”
• the metal frame is constructed to support the foundation above the ground, and typically includes two mattress length rails, each of which has an L-shaped cross-sectional shape so as to receive a lower longitudinal edge of the foundation therein.
• One or more cross-beams connect the rails together.
• Legs are typically disposed at the four comers of the frame. Occasionally, an additional leg or support member may be disposed at the center of a central cross-beam to provide additional support at the center of the mattress.
• the rails of the frame are commonly about seven inches above the ground.
• the foundation is typically constructed of wood, and may include a fabric covering thereon.
• the foundation typically has a thickness of about nine inches.
• An upper surface of the foundation provides a platform surface upon which the mattress rests.
• the height at which the lower surface of a mattress is positioned above ground when supported by such a metal frame and foundation assembly is thus defined by the length of the legs of the metal frame and the thickness of the foundation.
• Metal mattress platforms have also been used as an alternative to such metal frame and foundation assemblies, though they are less common.
• Metal mattress platforms generally include a layer of metal mattress support members and legs holding the support members above the ground.
• Such metal mattress platforms typically suffer from two primary drawbacks, namely stability and limited height.
• the legs of mattress platforms are typically longer than the legs of the frames of frame and foundation assemblies.
• the ability of the legs to flex increases and the platform becomes unstable.
• metal mattress platforms In compromising between the factors of height and stability, metal mattress platforms have typically been constructed such that the upper platform surface thereof is disposed at a height of about fourteen inches or less above the ground.
• Embodiments of metal mattress platforms of the present disclosure have been developed in an effort to provide a metal mattress platform that is high above ground, while still being very rigid and stable.
