After years of waking up with sore backs my husband and I decided to buy the Serta 4 inch memory foam mattress topper.

 We got a good price on it and placed our order.  We let it open slowly on it's own as instructed and then let it air out a few days.  At first it felt wonderful, very soft and comfortable.

 After a couple months, we took it off the bed.  It was hot and it seemed like you were down in something.  It was hard to turn over on this thing.
