Question: What do you have to do for a water bed?
Document: I have slept on a waterbed for years, this is a good standard unbaffled water bed bladder, it sloshes around alot exactly as it is meant to do.Seems sturdy, there is little more to say about it.
I am surprised that this bed is as shallow as it is. I almost feel like I have to overfill it to get it to be comfortable with two of us in the bed.
remember when you change a mattress to change your liner and heater too. Well built. no holes in mine like some people had. If you do not fill it up completely it will not be comfortable.
great quality for a great price- very simple to set up. I was pleasantly surprised by the thickness of the mattress vinyl- better than the one we were replacing
We have been using the mattress for 2 months and so far it has worked just fine. Filling it was just as easy as our old mattress and it seems very sturdy and fit our queen frame perfectly.
This mattress is not as deep as the one I replaced. Air bubbles are not as visible as the one I replaced. The Maroon color is very attractive. It is firm and I have not experienced any backaches since I started sleeping on this mattress.
Okay, it took a month for the smell of toxic plastic to dissipate. I survived and now have a full mattress 9&#34; deep! I had an expensive mattress before; that came with a hole in it and had to be patched several times and was half as deep. Glad to get rid of the old one.
In the process of filling the mattress, I got distracted and almost had a disaster by over filling. Caught it in time and deflated the excess. The mattress is perfect.
I mean that literally. We took delivery on December 3rd. We set it up immediately. It stunk and the stink just kept getting worse. It was so strong, our eyes would tear. We communicated with the seller, washed it over and over, aired it. waited three weeks and finally returned it. I have slept on waterbeds for more than 40 years and I never had one like this.
I LOVE IT. BEING AN OVER CUT MATTRESS SEEMS TO BE THE BEST IDEA THEY EVER HAD. NO MORE SLEEPING ON A HILL.
Answer: Agreed must have a frame wether wood or soft sided a pedestal so bed is not on the floor. If you chose not to put a heater on then its like sleeping on a bed of ice cold water. Waterbed sheets are easier then "normal" mattress unless you want to have a size larger ie king for queen bed. A hose to fill and the chemicals that go inside to keep the plastic soft, yes I have had one crack while sleeping. The other attachments make life easier for filling. A pump makes emptying the bed easier, can be rented for 10-15 bucks a day from rental companies.If you choose a free-flow be expected to be tossed around every time your partner leaves the bed. A fiber fill reduces the movement depending on how much fiber is in it.Soft sided  are nice can use normal sheets and isuch more like a typical bed
