Next bed I purchase will be a Temperpedic. Two sisters and one brother have them and love them. All of them have either back problems or arthritis. They wouldn't have any other mattress. My BF in TX has one also and loves it as well. My BF also bought one of those KS memory foam type mattresses from Overstock.com for her guest room for around $300. We stay with her for several weeks at a time and sleep on that mattress, it feels like a Temperpedic. I sleep like a rock on it.
