I wanted a memory foam mattress for a long long time and after almost one year of researching and comparing etc I finally ordered this mattress (medium firm). It had great reviews and you cant beat the price.It is absolutely perfect! support, but not too hard, just a little give. it is like sleeping on clouds.I am sooo glad that I bought this mattress - I finally get a good nights sleep! Delivery was quick, took 1 week and set up was easy - within a few minutes it expanded to 14in and there was NO chemical smell !!!The deep pocket sheets (Sealy from Overstock, of course) fit perfect!
