  • Fell Apart After 6 months!

    This memory foam was nice at first, but after only 6 months it crumbled, ripped, and tore which spread over the entire lower half of the mattress! There is no known reason or fault of ours that it should fall apart like that. We were very gentle with it and did nothing that could have caused this problem. A *** mattress should last longer than 6 months! I am very disappointed with this mattress and would not recommend this product to anyone. Another draw back is that it causes the sleeper to be warmer than usual, although I hear that is a common side effect of memory foam in general. And the last thing I would caution future buyers is that it is a smaller size than your mattress so sheets do not fit on it well. We ordered a queen and it was 4-5 inches smaller than our regular mattress. Over all I am very unhappy with this product!!!

  • Cloud 9 :)

    When I first received this memory foam, I was skeptical. The packaging was janky and not very professional. By looks, I was disappointed with the ratty box and plastic wrapped items. When I rolled out the topper, it had a slight tear in it (be careful opening it). However, after I rolled out the memory foam and placed it on my bed, I have been the HAPPIEST woman alive. (There was no funny smell to it either as others have claimed). The sleep I have had over the last few months has been some of the BEST in my life. I have always been a side sleeper, now I fall asleep in any position. This bed literally makes me narcoleptic as soon as I hit my sheets. Any guest that has come over and has slept in my bed has bought one immediately. It is great for sore joints (I am a runner) and for my mother who is a diabetic. Despite the bad packaging, I would recommend this topper to anyone. I call my bed my cloud and hate to sleep elsewhere because it is truly one of the best purchase I have ever made! :)

  • Linda in Central California

    I did an extensive amount of research before purchasing this topper. I had read all of the good reviews as well as the negative ones. I was prepared to get a stinky compressed topper that I was going to have to let air out for days before I could use it. To my surprise when I opened the box there was only a faint oder and I only had to wait a few hours for it to get its shape and the odor gone . I received it in a very timely manner and have been quite satisified with it. I would reccomend anyone who is looking to extend their old mattress's life at a reasonable price this is definatly the way to go. The only draw back that I have is that my bed is on a pedestal and by adding 4 inches on top of that its a little harder to get in bed than I expected but if I have to get a little stool to get into the bed that is only a miner inconvience compared to the comfort of the topper. and the money I saved. I was a little disappointed in the pillows though. I already have 2 Temper pedic pillows and was expecting something at least similar, the only thing they have in commom is there shape but considering the price difference I cannot complain too loud.

  • 1 yr and still fantastic!

    We have had our Serta memory foam mattress for 1 year now and it is still like new. It's like sleeping on a cloud! We are now ordering 4 more of them to try and make a mattress by stacking them on top of each other on the box springs and get rid of our hard mattress! Hope this works! If not, we have plenty of family members that have tried ours who will gladly take them off our hands!

  • Great topper, softer than 4# density

    We ordered the Firm mattress to go on our new bed from Overstock. I was quite surprised that there was no odor. Within an hour it was fully recovered to it's normal size, and I had a nice nap on it. After several nights, we decided that "Firm" was a bit too firm for us, so I ordered this 4" / 3# density memory foam topper, and now, our lovely mattress is perfect. As an added plus, it's much easier to make the bed by putting the mattress pad and fitted sheet only on the mattress topper! It was quite difficult to get even a "deep pocket" fitted sheet over the 14" mattress sitting deep into a box-type platform bed. As one reviewer wisely stated, it's easy to make a firm mattress softer, and impossible to make a soft mattress firmer! **There was a definite, unpleasant chemical odor to this topper, 48 hrs of airing did not make a dent in, so I sprayed it with Zero Odor, and poof it was gone! ** I would definitely buy this topper again for another room.

I found a similar one: Item #: 16322113 model #TP15150 but I cannot tell if these are the same product. Can you tell me are they different or the same?

  • Does the king size topper come with king sized contour pillows or are they standard sized?

    • Hi pllama223, the pillows are standard size. Thanks for shopping with us.

    • I purchased the full size and the pillows are standard size, but quality!

    • If you want to call them standard. They are small and they don't fit a standard pillow case. I don't use them much except to prop me when reading. My dogs like them :)

    • yes I have neck problems and they dont help it

    • I bought a cal,King and cut the sides off to fit my queen bed perfectly. I bought a pillow cover from Walmart with a zipper...cut theextra foam to fit cover and used 2 pieces to fit. This made a perfect flat memory foam pillow and now my neck doesn't hurt. I gave the rest to a friend and she now has a nice body pillow.

  • We sometimes use a heating blanket. Will this damaged the topper in any way?

    • Hi hall66, thank you for your inquiry. You will be ok as long as you do not leave it on day and night. Overexposure to heat may cause some type of discoloration or damage. As long as you only use a heating blanket when you are using the bed you should be fine. Thanks for shopping with us.

    • No a heating blanket will not do anymore damage than the heat from your body. I have been using a heating blanket on it for the past 3 months with no problems.

    • it shouldn't

  • are any matress pads or memory foam toppers fire retardant? also have been reading reviews and confussed as to the best one to buy looking for 4'"s serta has some reviews that say it riped or crumbled, comfort dreams also got some bad reviews and the egg crate ones say that you are really getting only 2" of memory foam. what are your reccomendations?

    • Thank you for contacting us kat58ted. No, our mattress toppers are not flame retardant. We have a few different 4” toppers so it depends on the customer’s comfort preference. If there are any issues with the foam within the warranty period you can contact us for a replacement.Please let me know if you have any other questions.

    • 4 inches holds up fine.

    • I have one of these on two of the beds in my house. One is about 5 years old and used the most and it has never ripped or crumbled. They are truly 4" - I love my memory foam pads.

  • I've read that gel memory foam stabilizes temperature better so that our body heat won't make us too warm by being cradled in the foam. How does this mattress deal with this problem??

    • I have had my 4 in. Topper for a few years now, although we only sleep on at during boating season. It seems to trap body heat and is warm even with a mattress pad and sheet. I bought it mainly to relieve back pain, and for that it works perfectly. Now that I have a portable air conditioner, I am comfortable sleeping on it.

    • I have no problem with mine. I can't tell it affects body temperature at all.

    • Thank you for contacting us, the Serta 4” topper has the ability to breathe so you will not feel too warm. However, if you normally sleep hot the gel products are a better choice as they are much cooler in temperature. Please let us know if you have any further question.

    • Mine is cooler than the foam mattress I have on another bed.

    • Haven't noticed if it is trapping body heat

    • It does seem to trap body heat.

    • It DOES tend to trap body heat. If you are worried about being warm DEFINITELY go with the gel one.

    • Yes these do trap in the heat. That is the only problem I have with this mattress. Once it gets hot it stays hot. I recommend that you get one with the gel in it.

    • true

  • Just received the topper and there is a noticeable smell to it. Is this topper safe? Are there any chemicals used to manufacture the topper that can harm our health?

    • The smell does go away. It may take a week or two, depending on where you lay out the topper.

    • Ignore the teeny-tiny bit of smell. It's barely detectable. Any manufactured product will have a small amount of smell. It will go away. Don't worry about it.

    • Thank you for your question. We recommend letting your memory foam topper air out for up to 72 hours. The smells associated with memory foam will usually dissipate completely with in a week or two.

    • the smell has not gone away with mine for over 3 weeks even tho I have been airing it out daily.

    • It does go away. Spray some Fabreese.

    • I let my topper air out for 2 weeks and still can't sleep on it due to the smell.

    • The smell does go away but the smell was strong on arrival and unable to use product immediately!

    • The smell goes away after a day or two. there is nothing to worry about.

  • Please go through the operation I outlined earlier. It is is still showing $139

  • Click on bedding and bath from your homepage, then select memory foam, then memory foam toppers,then queen sized. There you see this Serta 4inch topper and it plainly advertises the price of $139, but when you select it and go to the purchase page it then is $159

    • I think you caught it just when the sale price had expired. The price is as listed.

  • when looking at toppers on the site the price is $139 but when I select the page, the price is $159.

    • Thanks for your interest. The price on Serta 4-inch Memory Foam Mattress Topper with Contour Pillows is $159.00 not sure where your seeing the lower price.

  • Just received my memory foam topper. The box is really big that it came in and nothing else was in the box except the topper, no packaging material and no other box around the memory foam, the topper is only marked with the word queen. The outside seal on the box seemed to be damaged. Is this normal packaging?

    • Please contact our Customer Care Department if you feel the product is damaged.

    • Foam IS cushioning material. Why cushion something that is used as cushioning? If the pad is not damaged, don't worry about it!

  • Can you please tell me the difference between the Serta Ultimate 4-inch memoray foam topper, (#10031883) and the Serta 4-inch memory foam with 2 contour pillows (#10854919). Im trying to figure out which one is the best purchase, and what the difference besides the pillows really is. Or which one you would reccommend.

    • The difference in the two besides the pillow is the density of the top. You are looking at 3 or 4 pounds of density some prefer one over the other. The more dense the harder it will be.

    • I got the one with the pillows. I am very satisfied and it's about 5 years old.

  • I am buying this for a sofa bed. Can these memory foam mattress toppers be folded up in the couch? Or will it damage the topper?

    • You should remove the topper each time you fold up the sleeper, as it may not close properly with the topper on.

  • What is the return policy?

    • In order to receive a full refund the item must be returned in new or unused condition and contain all original materials included with the shipment within 30 days. If the product is damaged or defective, then you may receive a full refund even if the product has been opened.

  • I am looking for mattress topper to use it on floor temporarily. Which one is better - serta rejuvenator or Serta 4-inch Memory Foam Mattress Topper with Contour Pillows or other serta product?

    • If you plan to use it on the floor, we recommend going with the thickest pad possible.

    • Serta 4-inch Memory Foam Mattress Topper with Contour Pillows is better because the the density is 3 pound and thickness is 4 inch. Lesser the density more the softness and more the thickness higher the comfort.

    • Comfort Dreams Ultra Soft 4-inch Memory Foam Mattress Topper is four inches and four pound density which would be the best we have. The Serta Ultimate is a four pound density but I did not see it in stock.
