    • Disappointed!!!

      Wow, I've purchased memory foam toppers from Overstock over the years and have been very happy with them. This one is a major disappointment. I'm 150 pounds and I sink down to the bottom of it. This is suppose to be a 4 density, but it's more like a 1 or 2. Not only that, but it doesn't hold its shape and I've only had this thing about 5 days. Not worth the money I paid for it. Quality has gone down hill on so many things. We pay more and get less and less. I wouldn't recommend this topper to anyone over 50 pounds.

    • Good comfort, not sure about quality

      Rating this was hard for me. The good- it is comfortable. Especially if you like a soft topper. You sink right into this. I am very happy with the comfort. The bad- I don't think the quality is that good. If you grab ahold of it to move it too hard it will rip pieces off of it. I guess you could say its somewhat fragile, which I wasn't expecting. So, that being said, I am also concerned with how long this will last without smashing down flat and becoming useless. It doesn't seem like much more than a piece of soft foam to me. I would not label this memory foam, it is mostly just a piece of 4" soft foam. Don't confuse this with a Tempurpedic type material, cause I owned a Tempurpedic and this is nothing close to that material. If you want to add softness to your bed, and don't mind the price, I would say buy it, it will add comfort. If your big on quality and are looking for a true memory foam topper, you might not be satisfied with this. I just hope its not flattened out in a few months. If it retains its shape and comfort I'll be very satisfied with it, in the mean time I will be concerned.

    • 4 Lb. Memory Foam

      I have several manufactures' memory foam mattress toppers, and pillows, mostly Serta (from Overstock) and some of the RV matress sets (memory foam) and the trick seems to be, the higher the density, the more bang for your buck. 6 Lb. foam is the high-standard, but comes mostly with the very high-end products. This mattress topper was 4 Lb memory foam, that's why I chose it (probably the densest foam you can get with these mid-priced/low-priced toppers) and it's good. Best night's rest ever with memory foam; now I have it everywhere, in every bedroom in the house! rules!!!

    • Very good purchase

      I got this mattress a few weeks ago after looking and reading several different reviews on different mattress toppers. When I opened the package the chemical smell was rather strong, but after letting out to air for a few days the smell is almost gone. It is very comfortable for winter time or cooler homes, but I find that even when keeping my room a cool 65-68 degrees the mattress keeps body heat so well that half way through the night I'm kicking off all covers trying to cool off. So I would not recommend if you can not sleep well when hot but for aching joints and/or hip discomfort it helps. I still highly recommend this product considering cost, quality and overall comfort.

    • Foam Mattress Topper

      I bought this mattress topper to use in our travel trailer, underneath the existing mattress in our King bed. In our house, we have a Temperpedic, so I wanted something that would give similar comfort. I studied density ratings and decided on the 4" with a density rating of 4. Since RV beds are not sized like regular beds, I wasn't sure about the King size. As it turned out, the width was perfect, but we cut about 6" off the length. We camped for 4 nights and the difference was great. It was much more comfortable and no hard spots. The density is good for our purpose, but there is a BIG difference between this and a Temperpedic. When you press your hand into the foam, it disappears quickly. The higher the density, the longer the handprint should remain. The Pro is that because the density is less, the weight is less, too (about 35 pounds for a King) and that is better for weight control in an RV. I ordered the topper 1 week before our trip and shipping brought it to our door the day before we left. Unlike other reviews, there was no odor. We did leave it out overnight to "breathe and relax". I am pleased with the product and with the delivery.

    • Posh, Cozy, Lush!

      If you want your bed to hug you to sleep, this is the memory foam topper to get! It's amazingly thick and has a great density to it as well. It takes a little bit of getting used to but you'll never give it up once you do! Even the dogs sneak away during the day to burrow under the covers now; the bed is so posh! I've had thinner toppers before that I really liked but decided to spring for the 4 incher. Wow, I am really glad that I did! It's very luxurious and yet cozy at the same time. It's like sleeping in a hug, with my comfortor on top; totally yummy on those chilly winter nights!

    • I am accustomed to a Hard Mattress which is now getting soft due to age both mine :-) and the mattress. Therefore I need to know if this will make it feel firm again and does it come with a cover or do I need to purchase that separately (and where)? In Addition, does it require airing due to smell as others have indicated? Thanks so much.

      • Hello DejaVu1669w, this memory foam topper offers medium support comfort. It does not include a cover. We recommend item # 11756722 for a mattress pad.

      • Hello Alisi, the queen topper weighs approximately 30 pounds. I hope this helps. Please let us know if you have any additional questions. Thank you for shopping with us!

    • So I have a bed frame that only fits mattresses/toppers 74 (3/8)" x 53 (1/8)". Anything even slightly bigger and it will not fit at all. The mattress dimensions in your item description says this topper is 75" X 54". Are these just estimates? Is this topper smaller and can actually fit my bed? Please give me the exact dimensions for this item. Thank you.

      • Hi Vitashique, due to machine cutting manufacturing processes, there may be slight variances in the listed dimensions of this product. Thanks for shopping with us! S.R.

    • I bought the Comfort Dreams ultra 4 inch mattress topper. I am having a hard time finding sheets that fit properly. Any suggestions on what depth size sheets I should buy?

      • I found that it was easier to just put the sheet around the topper instead of the topper and mattress. Sheets stay in place and don't pop off at night.

    • What are the actual dimensions of the pads?

      • Hello James M, we have multiple sizes in this mattress pad. Twin would be approximately 39 inches wide x 75 inches long x 4 inches thick. Twin XL would be approximately 39 inches wide x 80 inches long x 4 inches thick. Full would be approximately 54 inches wide x 75 inches long x 4 inches thick.

    • How much does this King Size topper weigh?

      • Hello Mikey g, the King size topper is approximately 40 pounds. Thanks for shopping with us!

    • The details say to open within 72 hours. This will be a gift so it would need 4 weeks before opening. Is this a problem or can I order it and hold up on delivery.

      • Hello mac, in order for the memory foam to expend as it is meant to, you would need to remove from the packaging within 72 hours. Waiting longer could result in the memory foam not expanding as well. Thanks for shopping with us! A.S.

    • Does this memory foam topper come with a cover? the other 2 that I have bought came with a zipper enclosure and then had a "skirt" that came down over the regular mattress. If it doesn't - do you sell these covers?

      • Hello 123buck, this mattress topper does not come with a cover. We do sell mattress cover on our site though. Thank you for shopping with us! Amanda

      • No it doesn't which I thought would be a problem. It's fine, we put it under the mattress cover and it stays in place and is exactly what we needed

      • No it does not. I have a mattress cover and recently added a mattress warmer (which I was assured would not degrade the topper.) I'm just warm and cozy! phoenix258
