I bought this after realizing that my guest room mattress was long overdue for replacement and did not want to spend several hundred dollars on that. My daughter is using that room and has not stopped singing the praises of the ultimate comfort she now experiences sleeping on it. My 84 year old father came to visit and woke the first morning saying he can't remember sleeping so well and it had been years since he woke without back pain. Both my father and daughter could not order one fast enough for their own homes! DO buy some deep pocket sheets too, my old ones will not fit over the now very cushy bed topper.
