This specially designed, smooth top mattress offers an unforgettable night's sleep for anyone suffering from back pain. Thanks to its unique construction that combines the softness of an aloe gel mattress with the firm consistency of memory foam, sleeping on this mattress improves circulation by conforming to the body shape while adjusting to match body temperature.

  • Made of aloe-infused gel memory foam
  • First layer is 0.5-inch layer of 4-pound density gel infused memory foam
  • Second layer is 3-inch layer of 3-pound high density memory foam
  • Base layer is 4.5-inches layer of high density reflex base foam
  • Memory foam is resistant to dust mites and is naturally antimicrobial
  • Originally designed for NASA, this space age foam cradles your body, reducing pressure points that cause tossing and turning
  • Temperature sensitive foam adjusts to your body temperature so you stay warm
  • Improves circulation
  • Eliminates motion transfer and uncomfortable pressure points
  • Never needs turning
  • Disperses your weight evenly
  • Mattress can be used with an existing frame
  • Bed frame not included
  • Meets all flammability standards
  • Quilted jacquard cover with handles (not removable)
  • Mattress and bed frame sold separately

  • 8 inches high x 53 inches wide x 74 inches long

Due to the nature of Memory Foam the firmness level of every item is unique. Please be advised that even similar products may produce different firmness results.

    True 8 inches. No noticeable odor and I like the amount of firmness. I would classify it as medium firmness. If you want a really firm mattress I would not choose this one but neither is it pillowlike. The cover is very nice and thick as well.

    I purchased this mattress for my teenage daughter because we had a similar mattress for our bedroom and was very pleased with ours. This mattress was good quality and very comfortable. It was a bit more firm than I thought, but non the less she liked it and was very comfortable. We prefer these foam mattresses over a spring because my husband has back problems. After you sleep on a memory foam, you wont want to go back to a spring.

    Verified Purchase

    I can't believe that I have received the same product that garnered all those glowing reviews. First, the supposedly 8-inch mattress has never expanded to more than 5 or 5 1/2 inches. This has made for problems in its fitting between the side rails of the bed; plus the separate mattress cover with the special 1-inch gel foam is loose on the unexpanded mattress and can't be smoothed out. Second, much to my surprise, even after only one week of use, there are depressions along the side (where my husband sits on the edge of the bed) that simply never fill out again. This after only one week. What do we have to look forward to in the long term? I can understand the general policy of "no returns" on mattresses, but when a product is so far from satisfactory, that policy is unethical. I am very disappointed.

    Can't beat this mattress for the price. Works wonders if you have back pain. Provides a great nights sleep so you feel refreshed in the morning. Mattress is ready to use in 24 hrs with no order present. Small odor when first setting up, but goes away quickly..

    Bought this bed for my teenage son, he layed down on it and couldn't stop smiling! It has a slightly squishier feel than the other two memory foam mattresses we own, and sleeps cooler too. It has a very comforting feel and I would highly recommend this bed for an athlete, it relieved all my son's aching joints and tired back after a hard martial arts workout!
