[This review was collected as part of a promotion.] We've been sleeping on this bed a few weeks and find it to be a comfy mattress! It is VERY thick, so there is no need for a box spring, which is nice. But it is very difficult to find sheets that fit it. I am a side and stomach sleeper and find it to be just supportive enough, but a back sleeper or someone with back pain may want something a bit more firm and supportive. My last beautyrest mattress did dip a bit where I slept, so I'm waiting to sleep on this one a bit longer to see if I have the same issue with this one, but this one is a bit firmer than my last, so I'm hopeful!
