My son requested a mattress top for Christmas. After reading various reviews, I decided on the Bodipedic 3 inch memory foam. All the positive reviews were true. What a wonderful mattress top for a reasonable price. It molds and supports the body. I suggested that he air it out for two days, as recommended for the faint smell. But after seeing how nice this top is, he immediately put it on his bed. He said the smell is very faint and he had a wonderful night's sleep. This was a great buy!
