I had waterbeds for more than 30 years, I belive this is # 4 0r 5 and so far, the best by a big diference, and better, my wife loves it. Great for my back after 5 surgeries. I sleep like a baby!

Purchased in November 2019, My first impression was good. However, as time went by I started to notice the mattress was sagging more and more. The foam in the center no longer offered any support. I kept shifting my weight over to the other side to support my back. That worked for a while but now it seems as if all the center support foam has collapsed. Here it is just over a year and a half later (July 2021) and the mattress needs replacing. I have just ordered a different brand and hoping this one will last

I was hesitant at first to consider a waterbed mattress manufactured in China. However, my wife reminded me our last mattress, which was made in the USA, only lasted 7 years and the first one was returned for a seam leak. If you want a wave-less mattress-----this is it. I am 62 years old and have had a waterbed my entire adult life and this mattress is by far the nicest. I usually don't write reviews on purchased items; nevertheless, I had to on this one since there were a few negative reviews that contradict my experience. If you like waterbeds----you will love this one.

Good value for a truly waveless mattress.
