I was pretty skeptical about this mattress topper, but I have to say that I'm very impressed.  My hips and knees bother me at night, and I needed to soften my bed.  This mattress topper did just the trick!  It takes a day or two to get used to it, but now I look forward to falling into bed.  And my hips and knees never felt better.  I highly recommend this mattress topper.  I don't think you'll be disappointed.
