Unfortunately, i didn't research memory foam mattresses closely enough before i purchased this. If i had, i would've known that this 3lb memory foam mattress was better suited for side sleepers, and not for me, a fervent back sleeper. As a result, the mattress is a little too soft for my needs and i have been a bit of lower back soreness upon waking after 2 months of ownership. Initially it was great and i was totally sold, but now i know that someone like me who craves a really firm mattress should look for 5lb memory foam density. so there you have it. otherwise, i think this is a good quality mattress but just not for me. Back sleepers beware! side sleepers, you will probably like it. it's nice and soft and cozy!
