    • Perfect for my purpose

      I bought this for the back of my SUV so my older dog could lay in the back. It works perfectly to provide comfort for her old arthritic body.

    • Too soft & mushy!

      I bought this mattress topper, hoping to improve the comfort level on a very firm mattress that didn't have a pillow-top of any kind but it was far too soft & took away the back support I require with a firm mattress ...almost completely! I should have gone with the thinner mattress topper instead. Now I'm stuck with this since there is no way I would be able to re-compress & return this topper in the box that I received it in!

    • Best Mattress Topper Ever

      Ordered this new topper for college son. Have used toppers for a couple years. This one takes the prize. Thick! Feels as though you are being supported on a cloud. Quality product. Firm enough that it doesn't stretch out with a few uses and unbelievable comfort.. This was hundreds of $ less than in the store and well-worth the little extra to get this quality. It's a cooler feeling as well; not sweaty. Son can't wait to get to bed and he suggested we all get them. Love, love -- that's right --double love it. Recommending highly as the best we have tried.

    • freaking amazing!

      I have several problems with my back including deterioration diseases, facet disease and SI joint dysfunction. I also have fibromyalgia. So needles to say I have much pain when I sleep during the night and when I wake up in the morning. This has helped very much. I have pain in the buttocks that wakes me up in the middle of the night but this has made my pain much more manageable. My pressure points don't hurt anymore and my pain went from a 10 to a 3. Granted, if you suffer from severe and chronic pain, there is no "miracle", you can only make it comfortable and manageable. This totally does that! It returns back to it's original shape within seconds. It's soft yet it is stable with just the right amount of firmness. It keeps me cool at night yet warm enough without sweating. My dog absolutely loves it, lol. If you suffer from pain, get this, it truly helps.

    • our best purchase

      I ordered this for our king size bed because my husband and I both have back pain and problems with pinched nerves. I read a few negative reviews about the odor of the mattress and I must say there was only a very faint slight chemical odor. We laid it out as directed and it puffed to the required thickness within a few hours and the slight odor faded considerably. We put it on our bed and slept on it after having it laid out for about 12 hours. We love it, it is wonderful! It is a very reasonable price for the quality you receive. My husband is very pleased with it too. It fit our bed exactly and was easy to put on the bed and cover with the feathertop fitted cover. We did not have one problem with it despite other people's complaints. I will say that it takes getting used to when it comes to making love on it. But all in all, we love it!

    • Mattress Topper lives up to the hype!

      My husband hated his old mattress because he found it too soft, so we went out and bought the firmest mattress he could find. Unfortunately, it is so hard, neither one of us can sleep comfortably on it. We've owned it for 2 years, and it just never got "broken in." Now that I'm expecting our third child, I was giving serious consideration to replacing the entire mattress, but figured I should at least try a mattress topper first. After much research, I decided to purchase this product, and let me tell you, it's the best purchase I've made all year! * Excellent price for the thickness of the topper * Beautyrest is a name I know and trust * Overstock shipped it right out, and I had it within 5 business days * When we opened the topper, we set it right on the bed and let it air out for approx. 12 hours (the smell was pretty strong, but dissipated quickly!) * Cover that comes with the topper is much higher quality than I anticipated * Thanks to the gel/foam combo, this topper does not make us hot like a traditional foam topper would (and my husband likes to sleep with the window open, even in the winter, because he's always too warm!) Both my husband and I have slept better the last three nights than I have in the two years since we got our mattress. When I tell you it cradles my body and I don't move, I'm not kidding - and being pregnant, that's pretty exceptional!

    • This memory foam topper is comfortable .

      I bought this topper to replace a less thick topper, which never would stay in place as it wasn't enclosed in a cover. This topper is of great quality , very thick, sleeps like you are lying in a cloud it's so soft. Great value for the dollar. Would recommend this to buy for anyone. You will need sheets deeper to fit your bed, but it is well worth it.

    • The cover that comes with this topper tells me to unzip and remove foam before washing. there is no zipper. I don't see any other washing instructions. What is inside the very nice cover? The info calls it a fiber cover. How to wash?

      • Hello Barbara W., this item is not washable, it can be spot cleaned only. Sorry for the confusion. Thank you for shopping with us!

    • What does "density" refer to? What's it mean in terms of the topper itself?

      • Hello Nd1982, based on the 3.2 density of this mattress topper it is considered a "low density" memory foam topper, which basically makes it softer than medium or high density toppers. If you would like more information on picking a mattress topper with the right density for you, please follow the below provided link. I hope that helps, have a great day!

    • Is the fiber filled top cover removable from the memory foam so it can be washed?

      • Hello GaryLandess, this topper does not have a removable cover. We recommend a sheet or mattress pad to protect your topper. Have a great day!

    • Do I also need a mattress cover with this product or can a sheet be used directly on top? Typically when it is just the mattress, I would use a mattress cover then sheet. Not sure if the fiber cover is considered a 'mattress cover'. Thanks!

      • Hello katsat421, thank you for your inquiry. This awesome item could be used with a sheet or used as is. Thank you for shopping with us.

      • Hello matkk, according to the reviews the smell will go away after a few days to weeks. I hope this helps. Shelia B

    • I ordered the Queen size. My question refers to the cover pad. It says that I can wash it, but it also says to unzip the cover and remove the foam before washing. There is no zipper on the cover pad and there is no foam in it either. What am I missing? Can the topper pad be washed?

    • We have a very think mattress. Is there any reason we couldnt just put the fitted sheet and top sheet on the foam topper so they sheets arent to small instead of trying to make it fit on both the mattress and the foam cover?

      • Hello 4jeellis, thank you for your inquiry. Unfortunately, the information you have requested is currently unavailable. We will continue to try and answer this for you. You will receive an email notification once an answer is posted. Have a great day.

      • I just bought this, and our sheets still went on, last corner was a little tight, but they went!

      • There's no reason you couldn't do that but it would be easier to just buy some deep pocket sheets so the topper doesn't slide around.

    • We have an I comfort adjustable bed and it's to hot for my husband. He says he feels like the mattress holds the heat. Will this help with that.

      • Hello sullyexc87, thank you for your inquiry. Unfortunately, the information you have requested is currently unavailable. We will continue to try and answer this for you. You will receive an email notification once an answer is posted. Have a great day.

      • I don't feel like this holds the heat.

      • I'd think so. The whole point of the gel is to help keep it cool as far as I understand, I could be wrong though!

      • This mattress pad does hold some heat, but substantially less than a regular foam or memory foam mattress.
