This topper has given us a soft solution to a hard mattress. The mattress is a good one so we didn't want to replace it, but it is too firm and my husband's hands were hurting every morning. Before visiting the neurologist, we tried the 4.5 memory foam with fiber topper and it has worked for him from day one. No more pain in the morning and it is like sleeping on a cloud, very comforting. Canceled the doctor's appointment. Haven't used it long enough to comment on durability, but it seems fine so far.
