I've slept on a soft sided water bed for almost 20 years. Finally had to get rid of it. I normally have a really hard time sleeping on any other kind of mattress. This one is really comfortable. I'm so happy I researched mattresses online prior to buying otherwise I never would have found this mattress.
We are very happy with our tuft and needle mattress! It is very comfortable and very quiet. It also doesn't transfer motion across the bed much. I had heard that some people think the mattress is on the firm side, but to us it feels nice and soft like sleeping on a giant marshmallow! And it was a good price too.
My friend just purchased a King bed. I bought a queen for my daughter and I Love mine! Can't give a reccomdation about an item if you don't belive in it.
