Ordered mattress topper because I was having a major surgery and would be tied to the bed for several weeks. 4-inch mattress topper is just as described and very comfortable; it shapes to the contour of your body. Best part about purchase is I was able to purchase an expensive mattress topper for my king size bed for well under $100.00. I would definitely purchase this Item again and my husband is enjoying mattress topper as well. I can't get him out of the bed to take care of me :-). Would recommend to a friend. Only thing is be sure to let mattress topper air out for a day or so nefore putting it on your bed because it initially had a small smell to it; however after spraying it down with febreeze smell was gone.
