I bought one in the late 1990s. I needed a bed and found waterbed mattresses were cheap, actually they were all the same cost from single to CA king. I ordered the king size because why not and went to building the frame while waiting for the mattress arrival. I only had 1' left around two sides of the bed in my bedroom after setting it up, but it was the most comfortable sleep. I think the "waveless" feature was a big benefit. It did take a few days to get used. I now sleep on a high end pillow top bed. It's nice, but is second to the waterbed.
