    My bed was killing my back and was not getting a good night sleep. I had purchased this to see if it would help. It's only been a couple nights but I sleep better, no tossing and turning and wake up more less tired and ready for the day and my back doesn't hurt. Right now I'm loving it!

    I may not be a good person to review this but I feel inclined to give my review just in case! I bought this hoping to help my back with a mattress that was very uncomfortable however once I had this topper in the bed it felt like I had a horrible swayback. I think it has a great quality cover on it but just far too soft for me.

    Bought this topper based on reviews of other people and I'm so glad I did. I have had the best sleep I've had in quite some time. I have fibromyalgia and diabetic neuropathy on top of falling on February 2nd, 2017, and having 2 compressed fractures in my back. My husband and I love the topper but not nearly as much as our yorkies.

    I bought this after reading the reviews. It did not disappoint. It was kind of a pain to unwrap due to it being cold, it was winter when I bought it. After my husbands and I got it unrolled and set up it was love. I have 2 herniated discs in my back and I also have fibromyalgia. This has helped me get such better sleep. I'm very happy with my purchase. Anyone who lays on my bed comments on how comfy it is.

Questions & Answers

  • Q:

    "This seems to be the only memory foam mattress that states that it is "Firm" is this accurate or not? Thank you"

    Have an Answer? Be the first to answer this question!
  • Q:

    "Does this really help cool you down because the memory foam alone is torture when it comes to retaining body heat. "

    • A:

      The topper is comfortable but it does retain body heat. I am not sure if it is the memory foam itself or if it is the waterproof cover that retains the heat.

  • Q:

    "If I don't open the box at all when I receive it than I can send it right back and get a refund correct? "

    • A:

      Items must be returned in new or unused condition and contain all original materials included with the shipment. Here is more information regarding our return policy:

  • Q:

    "What is the ILD rating?"

    • A:

      The ILD rating is 12.

  • Q:

    "What is the density of the memory foam?"

    • A:

      This memory foam has a density of 3.5 pounds.

  • Q:

    "Dealing with a really bad divot on my side of the bed, I am 275-300lbs and have bad sleep apnea. Anyway, will this help with the divot? Do I need deep pocket sheets, and is it hard to get into and out of? Thanks"

    • A:

      Hi. this topper is on my Sleep Number bed (which I did not like until I put this topper on). I do not know if it will fix the divot but you will be comfortable sleeping on it. There was no odor, it is easy to unroll, and I have standard sheets on the bed (though the Sleep Number bed is a smaller mattress so you may need deeper pockets). As far as difficulty to get in and out of - I do slide off the bed when I sit on the side. It does add height to your mattress so take that into consideration.I hope this helped.

  • Q:

    "Description states: "Cover offers 4-inch gusset with a stretch-to-fit 17-inch contour skirt??" Is that really true making the total height 8"?? Is this a full 4" of gel memory foam??"

    • A:

      The gusset and contour information are correct. This is a 4" piece of foam and 4" topper.

  • Q:

    "Is the cover machine washable? Does it have a zipper?"

    • A:

      Yes the cover is washable. It does not have a zipper. The cover has really big corners and it slips right over the foam topper and the mattress.

  • Q:

    "Why did you choose this product?"

    • A:

      because of the gel foam

    • A:

      My cousin suffers from arthritis of the spine and recommended it to me. She recently purchased this exact item and has experienced the most restful sleep she has had in years. I have fibromyalgia and am hoping for the same positive results.

    • A:

      Price and free shipping

    • A:

      LOL! TMI, so that I can sleep in my bed with my husband again. My back hurts! I'm hoping this will be the solution to my back discomfort and then I can retire the reclining chair for only day time. :o) I'm waiting with positive thoughts that this will be the answer. Fingers crossed.

    • A:

      Waterproof cover

    • A:

      Liked the reviews. Liked the product description. Liked the cost

    • A:

      For my Mom for christmas and I like the waterproof cover for protection

    • A:

      Several months ago, I purchased a mattress topper from you. It is too soft and slips and slides all over the bed, so I'm trying this one.

    • A:

      It's 4 inches thick and had a waterproof cover with it. Needed to soften a firm mattress.
