Very happy with my purchase. The product arrived a few days earlier than projected. 
After sleeping on an already used memory foam mattress for 8 years this new one is heaven. I ordered firm and got exactly what I hoped for. My body, and especially my lower back, feels way less stiff each morning. 
After some time though, memory.foam may not be best, i find sleeping on my stomach a lot, tends to sink my stomach in more and is making my back feel weird every day. Maybe I should've ordered extra firm
