We bought this mattress from a Select Comfort Store at our local Mall; thinking this was going to be the greatest thing. A good night sleep with no aches in the morning. We have an Antique Highback full size bed and it being a small bed we at least wanted a mattress that would be great and worth keeping the bed. This mattress I would not recommend to anyone. We should have sent it back within the 30 night trial period, but thought we were not getting our numbers right to where they needed to be. Eventually it got worse and we were rolling into the center of the bed. Select Comfort was called and all they could do for us was send us a cheap mattress pad, which we paid for. They said this would resolve the problem. It did not! It was such a cheap foam pad too. It became to a point where we could no longer share the bed together. The couch was more comfortable!! Actually my dog's bed is probably more comfortable too! We ended up putting it on a spare bed until we can sale it. Which we feel bad to even do that. We don't want someone else to be out like us. We lost $2097.16 & $23.64 for the pad, which they called it a single chamber lift. Please know we rate this with No Stars, but had to rate it with one in order for this review to be taken.
