Great mattress for the price.
I used this to replace my original waterbed mattress (from the 80’s) in October 2015. It has held up very well, even with two (or more) people sleeping on it. At 260 lbs, I’m a big guy, but this mattress does fine. It is taller than my original mattress, and because of that, sometimes the sheets like to come off the corners.

I am really disappointed. I have owned water beds for 40 years …
When I went to fill this, the pull tabs on the cap of the fill tube broke off. I had to use vise grips to pull out the spout so I could attach a hose and fill it. I sent email to customer support asking for them to replace the cap so that I would have a cap that could be pulled out by the pull tabs. No response from customer support. I am really disappointed. I have owned water beds for 40 years and this is the first mattress where the pull tabs broke off, let alone breaking off the first time I tried to use them.

free floating island of discomfort.
I have had this for about 9 months, I couldn’t figure out why my bed was becoming less wave reduced, it felt like a full wave mattress. I took all the bedding off and realized the insides of the mattress had triple folded and were at the end of the bed. Now I have an island of padding free floating around inside my bed. One third of the bed is triple wave reduced, while the rest is straight water. I would not recommend this mattress to anyone. Total waste of my money.

blow it up with air mattress pump to get it into position better
Nice and comfy, fit well in hard side waterbed frame. Adult activities are awesome on this one!

it’s a great quality and should last a very long time
Though it’s deeper than expected, it’s a great quality and should last a very long time.

not good at all
I had this mattress less than 2 weeks and it had a small leak in one spot( I kind of left it go because I didn’t want to deal with it) but now 6 weeks later it has another leak. I would stay away from this

really comfortable IF ONLY IT WASNT LEAKING
The bed worked great for the first 2 days, until the bed started leaking. No joke there has been a slow leak coming out from some unknown area in the mattress. Pretty unsatisfied with my purchase.
