my wife and i decided to go to an all memory foam mattress. we chose the blue 100 because it seemed to be the perfect balance between soft and firm. sleeping on it for about a month now and it is fantastic. its not the kind of memory foam that you sink into. the support is great and it feels as if its forming around you but not swallowing you as i have felt with other memory foam mattress's. would highly recommend this mattress.
I purchased Queen size firmed memory foam mattress two years ago, it's very comfortable, still new after two years. It's great value for the money, I purchased another one for the spare bed room!!
