I'm on about week three of sleeping on this thing (got the "medium" level firmness). Honestly, it feels basically more like a 'firm foam mattress' than a true memory foam. I had to add a cushioned mattress pad to make it more bearable, which I'm told somewhat defeats the benefits of a memory foam. The description indicated 6 total inches of memory material, but I can only detect 3. I'm going to stick it out for a while, but I'm bummed it doesn't at least feel "closer" to a Tempurpedic than I thought it would. So for 25% the cost of a Tempurpedic? You have to make that call.
