I am very happy with this mattress, my back definitely feels more comfortable now when I wake up. The memory foam means you don't notice if your partner is moving around which helps to get a great night's sleep. It arrived compressed into a medium size box, which was great because you can take it easily to where you want to use it (although it's quite heavy) and unpack it there. We left it for 24 hours to completely expand and for the very slight aroma to disperse, and haven't had a single problem with it. Excellent product.
