Abstract

A collapsible mattress support for a box spring includes hinges on opposite sides of a middle cross bar. First and second side bars are pivotally attached to one hinge, and third and fourth side bars are pivotally attached to the other hinge.

A first distance between the axes about which the first and second bars rotate equals twice the common width of the bars plus a second distance between the axes about which the third and fourth bars rotate. In one embodiment, the cross bars are extendable. The components of the mattress support for Queen, California King and Eastern King sized mattresses fit in a packing box whose length is no greater than 45 inches and whose width and height are each no more than 7 inches.
