    It is extremely comfortable. My only complaint is it should come with a enclosure cover with zipper.Still haven't found a cover that fits. Patd2378

    one end of it was permanently folded back improperly and we never really decided why the many 'groves' were on one side. can't say it was any better or worse than most of this type. doesn't keep the heat away from you

    I was bit disappointed with this topper. It is good quality and it is soft. However, this pad is 2 pieces combined, the top piece is 1.5" memory foam cut into a pattern that makes it very soft. The bottom piece is 1.5" regular "hard" foam. When I lay on it, I immediately sink to the hard foam and can feel the pressure points on my hips. I only weigh 130lbs. Moved this to our quest bed but not good enough for my master retreat.

  • Great topper
    Verified Purchase

    Highly recommend this topper. Bought it to be used in a guest room and the reports came back great. One of my guests was an older gentleman with sleep issues and he reported that the bed was very comfortable.

  • Plush plush plush!
    Verified Purchase

    This has turned my firm Beautyrest mattress into plush heaven. I bought an 11" firm for the depth but it really was too firm. I have had other memory foam toppers from Overstock and been satisfied. However, this is the very plush conforpedic (Simmons also makes a firmer comforpedic mattress). It is 3" high is that is of concern to you. The ONLY problem is that the smaller "canals" tear so easily when just handling the mattress. Mine arrived with 1 tear in it and quickly got 2 more just from my fingers so you need to be EXTRA careful in putting the pad on the bed. Perhaps 2 people would be better than 1 to share the weight of 19 lbs. I always buy the Cal. King to cut down so that the pad goes corner to corner on my lower depth bed. It is quite easy to cut with heavy Fiskars. The comfort is amazing but know that it is plush!

    The Sleep Number bed we bought was very uncomfortable. It was the middle of the line-up and didn't have any padding to speak of. Either it was too hard or it felt like I was sleeping in a hammock with all the weight on my hip and shoulder. It needed some padding. I found this pad on, and decided to try it. It was thicker and much less expensive than what Sleep Number offered me. It still hurts to lie on my left side, but I'm able to sleep a lot better with the extra padding this mattress topper gives. It took a few days to a week or more for my wife to get used to it, but she's happy with it now, too.

    Love this mattress topper! I paid so much for my existing mattress I expected it would be comfortable without a topper but I was wrong. This topper actually makes me look forward to going to bed! And, as usual, the merchandise arrived in an extremely timely manner. Thank you Overstock.Com!

    I did not expect much from this mattress pad, but it has saved me from having to buy a new mattress. I can now sleep on my side comfortably without my shoulders feeling pinched. I weigh about 130 pounds and it's like sleeping on a cloud, for me. My husband, however, who weighs about 50 pounds more feels the pad is "mediocre" and still complains of backaches-although he says he feels better than before the pad.

Questions & Answers

  • Q:

    "Why did you choose this product?"

    • A:

      Excellent reviews.

  • Q:

    "Do you know how much this queen size weighs? We may have to cut in half if too heavy to lift over our head in an RV. We know that would void warrantee, but it may be what we have to do for weight lifting reasons and would not hold anyone responsible from your company. Is the edge I see on photo representative of the core also?"

    • A:

      Hello jellyfish, the shipping weight of this is approximately 14 pounds, without the shipping material it weights approximately 10 pounds. I hope this helps, have a good day!

  • Q:

    "Is it certipur certified?"

    • A:

      Hello Valued Customer, I hope your having a great morning. Yes this mattress topper is certified. Thank you for shopping with us.

  • Q:

    "If you cut the foam to fit a smaller bed, will it still work? Basically, I want to know if it's cut will it cause irreversable damage?"

    • A:

      Thank you for contacting us, we cannot advise you to cut the products. In doing so this would absolutely void any warranty associated to the product. Please let us know if you have any further question.

    • A:

      Yes, you can cut it carefully. I bought the king size for our master bed and decided I wanted something different so I cut it to fit the queen bed in our guest bedroom. Worked perfect.

  • Q:

    "I just ordered this last there any way to tell me when the product was packaged/compressed? Or is this information somewhere on the actual box? From what I have read online it says that these toppers are compressed for packaging purposes but should not stay packaged for more than 60 days...otherwise product may not last as long/lose flexibility etc. Thank you"

    • A:

      These mattress toppers are packaged when they are ordered.

    • A:

  • Q:

    "we have an adjustable bed, will this topper bend with height adjustments for head and feet?"

    • A:

      One of the qualities of this topper is to stay in place, so we're not sure if it will move around enough for an adjustable bed.

  • Q:

    "does the topper make you warm?"

    • A:

      It may be warmer than a traditional mattress.

  • Q:

    "The dinette table in our RV converts to a queen size bed. The 4 seperate cushons become the mattress. We have a padded mattress cover over them. My wife is having some discomfort with this set-up. Would placing the Simmons Comforpedic over the cushions and the padded mattress cover over the Simmons provide relief for her back?"

    • A:

      This would definitely help relieve some back pain she has. Mattress toppers are meant to give extra support.

  • Q:

    "does this come with a cover?"

    • A:

      Unfortunately, it does not come with a cover.
