What sizes of waterbeds are available?
All standard bed sizes, single, 3/4, king, superking and an almost infinite range of custom sizes up to 7' x 8' x 32" high (212 x 244 x 80cms).
Every manufacturer and retailer of beds will recommend that, for comfort, you select the largest bed that will fit into your room - that is equally true of waterbeds where the larger models cost only slightly more than the regular sizes.
