When I think of waterbeds, I equate them with a big pain in the ass...my lower back, to be exact. I've slept on waterbeds several times in the past, and after each extended period sleeping upon one, I'd awake with an increasingly sore back and memories of bad dreams about wetting the bed. Sure they were fun while awake for obvious reasons, but over hours of unconscious sleep, the old school water bed was a poor supportive surface for the spine. And getting out of one of these older waterbeds was like a core exercise of frustration; you'd have to swing out your legs first, and then push down to create a wave, then wait for the reflected wave to return to use it springboard out of bed...sometimes with cannonball effects. And darn if it wasn't a pain to fill that bed's bladder using a hose into the bedroom or repair a leak. But apparently waterbed technology has progressed with new "waveless waterbed" technology, using "hydraulics", also known as "baffles" and "fiber fill". Basically a flotation foam with polyester filaments are used to stabilize the motion normally produced by a liquid bladder, eliminating the unintended motion-in-the-ocean action. These new waterbed manufacturers claim up to a 98% reduction in waves, while retaining the unique water feature. Has anyone tried these new waveless waterbed mattresses? I'm curious what sort of sleeping experience these hybrids waterbeds provide compared to a spring, memory foam or air mattress.
