An adjustable, collapsible mattress support for a box spring has cross bars with slidably connected sections. A first section of each cross bar is fixedly attached to a band that folds around the second section and slides along the second section. A bolt that passes through holes in the second section slides into a slot in the band. By aligning the slot over one of the holes through which the bolt passes, the length of the cross bars can be adjusted to accommodate the widths of different sized box springs and mattresses. The first section is fixedly attached to a hinge plate. First and second bars are pivotally attached to the plate. The first and second bars pivot about parallel axes that pass through the plate at separate fixed locations and that are orthogonal to the plate. The mattress support accommodates full, Queen, California King and Eastern King sized mattresses.
