This is a nice mattress topper, however, we purchased this mattress because our expensive, hybrid mattress is too hard and hurts our backs and shoulders (we are both side sleepers) but this mattress topper was just as hard, if not harder.  I guess they need to make it know that this is a FIRM mattress topper.  Please know that if you prefer a firm mattress then this will be great for you.  I only gave it three stars because of the lack of description.
