The king size, 4 inch, 3.5 density, Gel Memory Foam, with the topper and free shipping was an incredible deal. This memory gel foam was everything I was looking for. It has made such a difference in my quality of rest/sleep. I used to wake up with a sore back and I constantly tossed and turned on my new mattress. I decided to give the memory foam a try. I am so happy I did!! What a difference!! It wasn't hot or warm feeling after a few hours of sleeping on it. It wasn't too soft and it wasn't too hard. It was also shipped and received on time as well. When opened and laid out on the bed, there was a mild order as mentioned, but after a couple of hours, it had dissipated. I will be purchasing another one for my son as a Christmas present. You can't beat the price and the quality is very good. The cotton cover is an added bonus. That saved me additional money. Other memory foams listed required you to purchase this separately. I am extremely happy with my purchase and do recommend this product.
