Did a search on the term "waterbed" and didn't see where this has been discussed. I had one as a teenager and into my early 20's. Never did understand why there was a mirror on the headboard/bookshelf thing. I always had fun burping it so it didn't sloosh, but it sucked not being able to rearrange the furniture on the spur of the moment. Later in it's tenure I got one of those motionless mattresses. Then I got tired of it. Got rid of it. Guess I just plain "grew up". Wouldn't take one now if you gave it too me.
My neighbor had one. It was a king sized one. Real nice... till it sprang a leak one night and destroyed the oak floor.
A couple I know has had one all their married lives - 30 years now. It was quite a kick to have sex on. But I prefer more controlability.
My parents had one. When they got rid of it we took the empty water bag and blew it up with air and played with it out in the yard, jumping on it and rolling it around until it popped. It was more awesome than a refrigerator box. But I wouldn't get one. I like my nice brick of a mattress that has held up very well - I got it when I was in middle school and still sleep on it.
My friends' sprung a leak in the middle of the night once. Hilarity ensued. Ya know, they're getting divorced after 30 years. I know he got the dog. I wonder who's getting the bed!
My SIL used to have one. The Mrs. & I crashed on it several times when we'd visit (SIL took the couch). This waterbed was NOT waveless, and was overfilled so that a big air bubble was always in the center, pushing us toward the edge of the bed. I hated that thing--would've rather taken the couch instead!
How do you fuck on the things? Can't possibly imagine how you'd get purchase with your knees for any thrusting. Doggie would be impossible, cowgirl would get downright lethal. What position even works if any?
When we met, the wife's preferred sleeping spot was a huge waterbed box with headboard, lacking the water mattress and filled with blankets. That worked OK.
You just have to hump one time and the mattress does the rest. Many times I woke up the next morning and we were still fucking.
Dude, trust me it works. Water beds are also great for using oils while having sex. Just pull the sheets off and go to town, then use some windex and paper towels afterwards and it cleans up great. Fucking while covered in Crisco is an experience you should check out.
Windex contains ammonia, which degrades the PVC used to make the waterbed bladder. 409, on the other hand...
