A water bed has an open top support with a water filled mattress. A mattress cover of a suitable soft cloth extends partially over the sides of the water bed mattress. Releasable couplers are secured to the spaced locations about the mattress and preferably at the four corners. Each coupler includes a coupling ring attached to the cover by an elastic strap sewed directly to the underside of the cover. The ring is slightly above the base wall. A diamond-shaped bracket formed of a thin, round and plastic covered metal rod is slipped between the mattress and the base wall. A small hook is integrally formed of the one apex of the bracket. The bracket is located with the coupling hook immediately adjacent the corner of the mattress. The user pushes inwardly on the mattress corner to clearly expose the ring and hook. The ring is then pulled to the hook and conveniently, readily and quickly applied. The hook is also shown secured to the frame by a connected screw.
