Abstract: An exercise device (12) which comprises two body support members (14). Components (16) are for pivotally interconnecting abutting ends of the two body support members (14) together. Four legs (18) are provided. A facility (20) is for pivotally attaching upper ends of two of the legs (18) intermediately between two opposite sides of each body support member (14). Two flexible U-shaped braces (22) are also provided. A structure (24) is for securing upper ends of each flexible U-shaped brace (22) between lower ends of one leg (18) on the first body support member (14) and one leg (18) on the second body support member (14) on the same sides thereof. The two flexible U-shaped braces (22) will support the legs (18) upon a floor (26), to allow the two body support members (14) to tilt in multiple positions to allow a person on the two body support members (14) to exercise thereon.

Abstract: An "L" shaped device having a fabric clamping means near the top of its vertical leg and inserted basewise between a waterbed mattress and its horizontal support platform. A sheet placed over a waterbed mattress may be secured by the clamping means (of a plurality) of such devices and thereby secured to the mattress surface by application of the invention.
