My husband and I have a sleep number bed. This mattess went in the guest room. Occasionally, we sleep in the guest room if one of us is ill (or snoring) so we've both had a chance to try out the mattress. My husband likes this mattress as much, if not better, than the sleep number bed. I like it just as much. The only thing I noticed about it is it still has a rubbery smell to it. I'm hoping that smell goes away after time because you notice it when your nose is up close to the mattress, even through a mattress pad and sheets, but but other than that, it is a very comfortable mattress and I highly recommend it. I wouldn't let the smell keep me from buying.
