ABSTRACT:
An expandable support frame for providing supportive confinement for variously sized flexible mattresses. The frame includes a support member suitable for being positioned on a supporting surface such as the floor. An expandable mattress housing is mounted on the top of the support member and includes interlocking segments which define a supportive base bound by four vertical sides for retaining the mattress. A housing expansion segment combines with the housing segments to expand the effective size of the housing for supporting various size mattresses.
