We purchased this mattress after a year worth of research on memory foam. Seemed everthing about them were pretty much the same except the price! We could not be happier with the purchase from Overstock. The price was great! The product is great! We ordered the medium firmness. The lack of back, neck, & shoulder pain makes it that much sweeter!! It came to the house in record time! 2 days from date of purchase! The mattress arrived before the email, confirming it was shipped! Amazing!! It was easy to open, unwrap and place on our box spring. It decompressed immediatley once we started to un-roll the mattress.Within the first hour it was already at 12 inches! It is a beautiful looking mattress. Perfect weight to manuver and make-up. Our queen sheets fit perfectly! There was no smell at all and we love the height it gives us! We recommend this mattress to anyone who is considering purchasing memory foam. YOU WILL NOT BE DISAPPOINTED!!!
