Memory Foam Do's and Don'ts:
  1. To maximize memory foam expansion; remove from packaging within 72 hours of receipt.
  2. This product arrives very tightly packed. Please unwrap and allow 48 hours for this product to return to its original shape.
  3. Being sealed in plastic packaging sometimes traps odors. A few hours of airing usually removes the odor.

    This is good quality but I did buy a thicker one as this guest room mattress is very firm. If you have a very firm mattress I would get a thicker one.

  • 4" Memory Foam Topper - Awesome!
    Verified Purchase

    My husband and I were waking up each morning with sore backs from sleeping on our Queen Size Bed. We decided to try the memory foam. We did a little research and found that most people were recommending the 4" memory foam. So, we ordered it in Queen Size. The foam arrived very quickly and we unwrapped it and allowed it to form into shape. We then placed it on top of our mattress. It fit perfectly. Our sheets were even deep enough to cover our mattress and the 4" foam. (Deep pocket sheets a must!!) It was very comfortable and we found that we did not get up every morning with sore backs. It was an excellent choice for us and saved us $800 we would have spent on a new mattress! I would highly recommend buying the 4" topper. Now our bed is so comfortable, we can hardly force ourselves out of it in the morning!!!!

  • Memory foam mattress pad
    Verified Purchase

    Customer service and delivery were excellent. This is the third pad I recieved. The first was fine but the wrong size(my mistake) The second was dirty and damaged and both were a nightmare getting them back in the box. The third was damaged in three places, three six inch splits all the way throught the pad. I decided to keep it as I couldn't get it back in the box. It is comfortable and truthfully you cant' tell it is damaged. I'm dissappointed with the quality of the merchandise and wonder if all overstock goods are damaged in some way. It will be some time before deciding whether to buy anything again. the refund to my account on the first purchase was made in a timely and satisfacory way. Thanks for asking for in-put.

    Very comfortable and rates 5 stars on all points except for size. I ordered a California King and it is approximately 3-4 inches less in width and length. It is almost impossible to shrink down for return shipping, I had no other choice but to keep it.

  • Fall asleep immediately
    Verified Purchase

    I bought this topper after a friend recommended a 2in one. I went for the 4in because it was still less than $200 and seemed like a good deal. It is absolute luxury. I fall asleep so quickly now when I get into bed and even my boyfriend who always has trouble sleeping because of sinus problems falls asleep within minutes. It is almost exactly the same size as my queen mattress (maybe an inch short length wise) and there were no cuts or tears in it. I let it air out and expand for 24 hours before putting it on my bed. The smell stayed for about a week. I do recommend that a cover is bought. Overall, I am very happy with this purchase and have already recommended it to 5 or 6 people.

  • Great Produce
    Verified Purchase

    I would highly recommend this product. I had two discs removed in my neck and have not had a good night sleep in over a year. Not kidding, when I laid this pad on my bed and let it rise. WOW it has been wonderful. I am sure it will last it is only me on it but still. Great investment. Much cheaper then buying a new mattress set. That was my next step. Smells of chemicals for a while but I would take the smell over sleep anyday. The smell goes away in a couple days. Kind of like the smell of paint.
