I've had a waterbed for the past 12 years. I don't want to even think about any other type of bed! I love sliding into a heated bed. I never have a bad night's sleep on it. But, waveless is the only way to go. The wife and I just went from a queen sized to a king sized waterbed. The neighbors were giving away the bed frame, heater, nice headboard/bookcase, and 4 drawer pedestal. $150 for the bladder and liner, $30 for new waterbed sheets and $10 for a can of stain and wax and we have a nice comfy kig size bed!
