Sculptured, stretchable waterbed mattress with aesthetic appearance

An aesthetically pleasing, low tension waterbed mattress having a polymeric top wall provided a sleeping surface, a bottom wall, and side walls, the top wall having a length and a width, the length being greater than the width, the ratio of the surface area of the top wall when pulled taut to the surface area of the top wall when not pulled taut being at least 1.05 and less than 1.2, the top wall having a plurality of curvilinear expandable folds formed therein so that the top wall stretches when a user lays on the mattress for avoiding excessive pressure on the user, at least a portion of the folds being in a regular repeating pattern spaced apart from each other by a distance, L, of from about 1/4 to about 3 inches, the ratio of the height of the regularly repeating folds to L being from about 1/8 to about 1/2 so that the mattress has an aesthetically pleasing appearance,

• the mattress capacity being at least 11 inches of water, and
• the mattress containing (i) water in an amount of at least 3 inches less than its capacity and (ii) a baffle for reducing wave motion in the mattress when a user sits or lays on the mattress, wherein the folds are formed into the mattress so that the width of the top wall increases by a greater percentage than the length of the top wall increases when a user lays on the mattress aligned with the length of the top wall.
