Abstract
Abstract A lightweight, foldable mattress support frame with head and foot sections insertable between a mattress and a box spring support. Head and foot sections are pivotally connected and manipulated between a flat position and positions at selected angular dispositions. Flexible straps interconnect marginal portions of the frame. Pivots between the head and foot sections provide a minimal amount of disturbance of a mattress supported on the frame between the marginal portions of the frame.
