I love my mattress topper - it's so comfortable. The description is very accurate and the topper really is 5.5 inches so you want to ensure you have deep sheet pockets or they will not fit. It's also very important to allow your topper to unfold and air-out. It does not take long for it to regain it's original shape (a couple of hours). I was going to buy a new mattress becasue my back was "killing" me - in only 3 nights my back is already feeling better. I am very happy with this purchase and the quality of the item is great!
