Important: Bed Frame & Foundation

Waterbeds are significantly heavier than conventional mattresses and require a frame or foundation specifically designed to support the weight. Most standard bed frames are not rated for waterbed use. We carry wood waterbed foundations (similar to a box spring) designed specifically for our beds. Please contact us before ordering to confirm your frame or foundation is compatible — we're happy to help.
