We are loving our Beautyrest Silver Extra Firm Mattress. While it's extra firm which is great for the extra support we need it is still super comfortable. We are back and side sleepers and this just feels great at night. Another great feature is that they are made to keep their shape for the life of the mattress. All of our other mattresses seem to lose their shape....Oh, and with the firm mattress you really can't feel anyone next to you moving around which really helps for a better night's sleep!
