      After reading other reviews on this mattress, I took the advise of 1) unboxing it in the room and 2) propping it against an open window for one overnight to eliminate the odor; both excellent suggestions. The mattress is all you could want for comfort and design. As it is new, I cannot give any hints to longevity, only to a much better sleep and night.

    • Much firmer than I expected!

      After sleeping on a mattress that was way too soft for years, we decided to buy one that was firmer. This mattress is very solid once it opens. It gives a little, but it's still much firmer than I expected. We will need to get a topper to soften it a little. It has good support and it's a great base, but I want a little more give on the top. It does not transfer motion and I can't even tell when my husband rolls over or gets out of bed. I was pleased to see that it was manufactured in the town I live in. Delivery was super fast.

    • Great mattress...a little too firm

      This mattress is great. It arrived in 5 days after ordering it. It is the perfect height for our platform bed without a box spring. It has a lot of support but is a bit too firm. It's hard to buy a mattress online without testing it first! I thought the memory foam might soften up a little after a while but it didn't so we went ahead and bought a cheap memory foam mattress topper and put that on which made the mattress perfect. There is a lot of support from the mattress and the pad on top adds the perfect amount of cushion. Considering you can buy the same mattress on Amazon for **** more, I think this was a great deal and would absolutely recommend it.

    • Made in U.S.A

      Very good mattress, Mattress is firm but is still comfortable. Cover is very nice as well. I m really happy I went with this mattress because it is made in the U.S. Although the mattress did not expand to 12 inches though, more like 11. I m still debating getting a topper. All in all, I am satisfied.

    • Great mattress at a great price

      Happy with the purchase. I like firm mattresses. My wife initially thought it was too much on that side, but warmed up to it eventually. Nothing in the technical details department, I just like the fact that it's a foam mattress at the price that I paid. It was recommended to me, and I'm happy to recommend it to whomever it reading this now. Good luck!

    • I am really considering getting this mattress at this deal, but I'm scared of getting it and it having a great pet peeve of mine. HEAT! Some of the reviews say its a problem others doesn't. Is there any fair info you can give me and in the event of getting it and heat is an issue what are cost effective solutions to problem. I seen one review say they woke up sweaty. Really don't want that.

If you search for "king gel memory foam mattress" in our search bar, you will find a wonderful selection. Thanks for shopping with us! A.S.

Have a great day and thanks for visiting our site.

      Guidelines
      • Hello eliast, This is a new item so there are no reviews yet. From my experience with memory foam I think this one would be better than the 8 inch because it has Three foam layers where the other one only has 2. Happy shopping!
