Soooooooo comfortable

Waterbed fan from Hamptons, NY– Verified Buyer

We have had a waterbed since we've been in our 20's and now we're in our mid-50's. The last two mattresses we had were the "sloshy" kind, which was fine when we were younger but now it was hurting our lower backs. So we opted for this mattress, which has baffles in it, and it provides just enough firmness to be comfy but yet it still has the movement that we enjoy and it molds to our forms. We highly recommend this bed if you're looking for a firmer (but not too, too firm) waterbed mattress.

No more suffering - hooray!

Michael Sandstrom from Albany, GA

My May 2011 purchase of this matress was a life saver. I suffer from neck, shoulder and arm orthopedic problems which are no longer debilitating. I'm drug free where I previously needed either vicodin or neurontin. Great wave control and build quality. Highly recommended.

great products/ very quick delivery

Happy customer from Tazewell, VA– Verified Buyer

I've had a water bed for 27 yrs. My second mattress (20 yrs old-same brand) developed pin hole leak. Went back to same brand, but this new mattress is FABULOUS! The liner is excellent, improved over last model.

Comfortable and a good buy

Kreitz from Wisconsin

The mattress is comfortable and was an excellent replacement for our 20 year old waterbed. The comfort cloud mattress has great support - much better than our previous mattress. [...]

Hope from Kernersville, NC

[...] this is the best mattress I've ever slept There is little movement, but molds to your body. I have to pry myself out of bed in the morning it's so awesome! I'm looking forward to crawling into a warm bed all winter. I highly recommend this product and company!

They just get better!!

Mim from Southern Ohio– Verified Buyer

I've had a waterbed since 1983. Their construction has improved tremendously! This past year I was forced to sleep on a hard mattress (due to circumstances beyond my control), so I haven't had a good night's sleep since until my new mattress arrived and was set up. I can sleep again!
I love my waterbed and will never be without one again!!!!

comfy and very snoozable

sherm from Cape Cod, MA– Verified Buyer

This mattress has a lot of support. It moves a little, but quickly settles. It seems extremely durable, and it is extremely comfortable.
