I bought this mattress to replace my own mattress. It is a dream. It is firm yet allows your body to sink in, to be cradled by the mattress, to provide support everywhere. Even my legs get support! I had been searching for a mattress for years to provide lumbar support and I've found it. I love this bed. Buy it for yourself, your kids, your guests, your parents! (Note: I am 5'7", under 120 lbs).
