Our matress is fit into a queen size waterbed frame. The matress feels firmer then in the store. We contribute this to the right fit on the sides of the frame. The measurements are off we think. We measured the bedframe and thought we would be fine.
Meets expectation and a very well priced product compared to other comparable brands. I moved from a Sleep Number - M7 mattress and feel that I spent double the amount for less comfortable and quality product.
The concept is great, but I find half way through the night I wake up with my back hurting. I hope this goes away and it is just an adjustment period with a new mattress. Time will tell.
