My son was looking for a new memory foam mattress, and I was shopping with him. I decided to look on Overstock.com, and found this one. This mattress offered everything or more than the other memory foam mattresses he had narrowed his search to; only the cost was at least $200 less than any of the others. It arrived quickly, we simply took it out of the box and plastic wrap, opened it onto the bed and within 5 minutes, it was done! He LOVES the mattress - says he sleeps better now than he ever has in his life. My husband and I are going to order 2 more in the near future for beds in our home.
