ABSTRACT:
A plurality of like, parallel, transversely extending assemblies connects an upper frame and a lower frame together. The frames are alike, each being generally rectangular and having an open center, and are disposed in parallel horizontal planes with the upper frame above the lower frame. The assemblies allow the upper frame to be moved downwardly towards the lower frame while being always maintained in a horizontal plane.
Each assembly includes two opposed roller means that are pushed to roll inwardly towards each other whenever the upper frame is pushed downwardly. A tension spring biases each roller means outwardly, to maintain the upper frame in its original position when no weight rests upon it.
The entire device can rest upon a suitable support.
The upper frame accommodates a removable padded upholstered board constructed to resemble the top of a box spring.
