    The mattress is uncomfortable but the worse part is trying to deal with Overstock to return the product. First they tried to overlook the 30 day comfort guarantee and next they wanted to charge 1/3 of the cost of the mattress to return it. I would have been better off buying this from a local store and paying more to avoid the hassle and headaches.

    I ordered this as a bed for a spare bedroom, but I have been sleeping on it for the past week. So far it is outstanding, but it is definitely very firm. I was blown away by how quickly it was delivered. The deleivery process was smooth and professional.
