The Nova Hybrid is now my third so called foam mattress in four years. The first, a top of the line Therapedic, was so hard and unyeilding that it ended up in the guest room after a year or so. Obviously, guests don't extend their visits! The second, A Serta Black, was somewhat better but after two years it failed to spring back into shape after a nights sleep. After much research and a "test drive" in the Orlando store, I settled on the Nova Hybrid. The pillow top gives the comfort I wanted and the inner springs are very supportive. I think I finally found a winner for both comfort and back support.
