When I was in 8th grade (during Carter's presidency!) I got a waterbed. I still use the frame, but for the past decade-plus I've had an ordinary mattress in it.
I've missed sleeping on a waterbed.
Lately I've been waking up several times during the night, it's not good rest.
A few weeks ago I went to the same store where the bed was purchased (it's probably the only waterbed place left in Sacramento) and ordered a new mattress. They custom-ordered it from a company in Carson City. A couple days ago it came in.
I set it up and filled it on Wednesday. It would take longer than an evening to warm up, though, so my sleep that night wasn't very restful--unless you consider sleeping on an iceberg restful, which I do not.
But last night...last night it was fully heated. The new fleece sheets were on. And I crawled in. So soft, so toasty warm. I slept for 6 hrs before waking up, turned the pillow over, and slept for another hour and a half or so. It was heaven.
I'm looking forward to being tired tonight so I have an excuse to sleep in it again.
