Even the more expensive mattress brands utilize polyurethane as an additional cushioning element.Waterbeds were the rage back in the 60′s. They were extremely pressure relieving, could be heated to any desired temperature and were easy to drain and move. At one time the biggest negative with them was leakage if their plastic membrane were punctured and the wave motion caused when you moved around. Baffled chambers solved most of the movement problem, but after several years of use the real problem showed up. The human body carries about 60-percent of its weight in the lower torso area. Soft surfaces like air and water allow this area and the hips to sink further into the mattress than the shoulders. This lack of proper alignment puts pressure on the muscles of the lower back. Over time these muscles weaken and back problem ensue.

Many waterbed sleepers began to have a lot of back problems and thus, for all intent and purpose this support issue relegated the once popular waterbed to feather bed status. Waterbeds were overshadowed by the memory and latex foam revolution as sleepers once again began looking for the next mattress breakthrough.

The Good

Sleeping on water is a fun experience for most. Waterbeds offer the ultimate in body contouring. It effortlessly reshapes as your body moves during sleep, supporting every inch of you. Also, there’s no dust build-up here. Waterbeds are highly dust mite resistant. Between their durability, comfort and support, waterbeds have a 78-percent overall owner satisfaction rating.

The Bad

Waterbed mattresses can be easily punctured, which can result in a wet disaster. Another couple notable set backs of waterbeds are their elaborate assembly procedures and weight once fully set up. At their heaviest, waterbeds can weight up to 1,000 pounds when full of water.
