bought this as a housewarming gift for a close friend and she LOVED it. her mattress was old and she couldn't afford new one, and this topper completely rejuvenated it as the description implies. so much cheaper than trying to buy a new mattress!
This is actually only 1.5 inches of memory foam. The rest is just a regular sponge-like foam. I have had this for less than a year and it is completely worn out (and has been for several months). I am actually in more pain now, than when I bought this. Much better off with an actual 2 inch memory foam topper. Bad purchase!
