  • This product arrives tightly packed in a box sized to be portable; once you unwrap it, you can sleep on it the same night, although it may take 48 hours to return fully to its original shape.
  • Memory foam is inherently comfortable and supportive, no matter how firm it feels; similar items can vary in firmness due to the nature of the foam
  • Product is vacuum sealed at the factory for efficient shipping; vacuum sealing sometimes traps odors, but once opened, a few hours of airing will usually remove the odor

  • read the print

    It states 4 in memory foam topper, however only an inch to an inch and a half is actually memory foam. The other 2 1/2 to 3 inches is just regular cheap foam. If you really want a good memory foam pay the extra 50 bucks and get the full 4 inch memory foam.

  • Fantastic!

    This is our second one - we bought a too hard mattress for home and this saved it - then we had to move temporarily for my husband's job and moved into a very nice furnished apartment - but we were there 4 months when I went home for a visit (slept in our bed @home) and realized just how awful the bed at our temp apt was - bought another one of these and I am sleeping great!! You could put this thing on the floor and sleep great! Didn't smell - unrolled it at 3m and put it on bed at 6pm - slept on it that night. Can't say enough - you won't regret this buy! Even my husband who like firm - loves this - I like soft and it is great for us both.

  • Topper of memory foam is ONLY 1-1/2"

    I have purchased Serta memory foam toppers over the years as they wear out. I did not notice the smaller print that the memory foam was so thin. Instead of 4" of memory foam as this topper should be, Serta has decided to cheapen this topper by using regular foam with a thin layer of memory foam on the top of it, and only on one side to boot. Even sorrier of Serta is the fact that they do not cut the king size true to the shape of a king size mattress. They cheat you out of a good 3", which for tall people that need every inch of a king size, means your feet hang off the topper. Way to go corporate America (Serta)! Cheapen your products, charge more, and pocket the huge profits!!!

  • Serta Memory Foam

    I was not pleased with the one ounce memory foam topper as it has limited quality for support. I wish I had done my homework to locate atleast a five ounce or even nine ounce memory foam. I predict that afer one month or less, I will not even know there is a topper on my bed. This has been a poor purchase, in my opinion.

  • Superior sleep aid

    I have been looking at these foam mattress toppers for a year and finally decided that it was worth it to try one rather than buy a new mattress. It came tightly wrapped in plastic and I unwound it on the floor and let it sit as the instructions stated for 24 hours.One of the main things I noticed was there was "no smell" to this product. I have a keen sense of smell and would not be able to use it if there was a chemical smell on it. We put it on our king size bed under the fitted mattress cover and it fit fine. It made our bed seems much higher but the sheets fit too.After the first night I felt an amazing difference when I woke up. Being skeptical, I waited for another night to see if my husband felt the way I did. We both agreed that we were waking up without the usual back aches and pains we had been experiencing. We both are sleeping better and waking up refreshed after a good nights sleep.We are thrilled with it and highly recommend this mattress topper to anyone!

  • good buy

    For the price the quality is great. It is a little firm for my liking. We bought it for our camper it will have to be cut down in size just a bit. Overall good purchase.

  • Very Comfortable

    I had purchased a firm mattress, but knew I wanted to add a foam topper for real comfort. This is so comfortable. I will say it did smell a bit at first, but that went away. I like a bit a firmness. This provides support, but also molds to my body for real comfort. I don't feel as stiff in the morning. I love this topper. I have heard other people complain that foam toppers can get hot, but I haven't had that problem and I can get a bit warm at night.

  • Is this topper CertiPUR-US certified?

    • Hello Natalia, this topper is Certipur US Certified. Thank you for shopping with us! A.C.

  • Is it fire resistant?

    • Hello lienka, this mattress is fire resistant. Thanks for shopping with us! Amanda

  • Or, what if I just used this mattress directly on my hardwood floor? (I am small, i weight less than 100 lb). Would it be enough that i would not "bottom out?"

    • The only way to know for sure is just try it and see, but I think it would be comfortable with your weight.

    • Thank you for your inquiry, zixa. Unfortunately, we do not weight test our items. We apologize for any inconvenience. Please let us know if you have any other questions. Thank you for shopping with us.

  • Hi, I am trying to decide between the Serta Rejuvenator Dual-layer 4-inch Memory Foam Mattress Topper, and the Serta Ultimate 4-inch Visco Memory Foam Mattress Topper. So i see that the first is dual-layer, which i heard was good for extra support. Bu the second is an extra pound of density, being 4 lb instead of only 3 lb. So I don't know which advantage is better! Anyone have knowledge on these points? Thanks!

    • Thank you for your inquiry, zixa. We are unable to determine which advantage is better, but the difference in these toppers is that Serta Ultimate 4-inch Visco Memory Foam Mattress Topper is a bit more firm. We hope this helps. Thank you for shopping with us.

    • I'm just taking an educated guess here, but I have the dual-layer topper and it's wonderful. I've had it five years and it's still as good as ever. BUT...the Visco memory foam is newer technology so an improvement over what I have. Either way, I can promise you you'll get many nights of great sleep...they make that much difference!

    • thanks paminthegrove for your reply! just wondering also if you can let me know your thoughts on this: the dual-layer option might be better on the hardwood floor rather than placed onto my lumpy bottomed-out (non-memory foam) mattress? as the underside might be more stiff being not the memory-foam , and therefore might sill be uneven? The other option i think might be, i get the Ultimate 4-inch Visco Memory Foam choice, and use it on my lumpy mattress, it being the memory-kind with more "give" on the bottom side, which might fill in the gaps to make it all more even? In which case, i've got the extra cushioning by using both mattresses?

  • Could you put this directly on top of a box spring?

    • Hello elc280, yes you could put this over a box spring. I don't know how comfortable it will be though. Have a great day!

    • Only if you weigh 95lbs. otherwise you sink to deeply. Perhaps on a box spring with actual springs, or you'll feel the box spring and putting it on a mattress you sink even further.

    • No.

    • yes

    • Yes

  • What is the benefit if having 2 topers rather than 1 if they both equal 4 inches.

    • Hello forever1118, I think that would just be the same as having a 4 inch topper. Have a great day!

    • Depends on which topper you are talking about. 2 4" toppers can move from each other unless you have a pad to put over both.

    • It shouldn't matter, but rather convenience. I found it nice to have this particular combo.

    • would see no benefit. only need one.

    • I just got my topper and I am able to sleep with comfort and get out of bed without a sciatica attack. I just have one

    • Not sure we bought the 4 inch and it is awesome.

  • I have a too soft mattress. Can I remove the mattress and put the 4" Rejuvenator on the box springs and have a firm but comfortable solution?

    • Hi overwhelmedbernie, while this may work we can't tell how comfortable it will be for you. In this scenario this is a good choice for a thick topper. We hope this helps you. Thanks for shopping with us.

    • I wouldn't we put ours on top of a cheap camper mattress that we could feel the springs through and it felt like a new, expensive mattress.

  • can I put this topper on any matress?????

    • buy the right size and you can.

    • I tried it---I think the 4 inches may be just too much...kind of felt like sleeping in mud and was difficult to turn over. Finally took it off and gave it away...

    • yes

    • Yes, that is what I did. It works fine.

    • works great on my older mattress. feels like new! i move around alot in my sleep, so have to adjust it frequently. like sleeping on a giant marshmellow. would buy it agin.

    • Not on a pillow top

    • I used it on my older mattress instead of buying a new mattress and it does a wonderful job of support and comfort.

  • How much difference will there be in support between a 4" rejuvenator and a 4" eggcrate?

    • Thank you for your interest on the Serta Rejuvenator Dual-layer 4-inch Memory Foam Mattress Topper. The difference is on the materials that are used on both items. Most eggcrates can be turned over and be used as a rejuvenator.

    • I have purchased 2 Serta Rejuvenator pads. I absolutely love them, they add so much comfort and support. I have tried the eggcrate before and I didn't like it. Hope this helps you.

  • We have an odd sized bed. Full is too narrow and queen to wide. Can we cut the Memory Foam Mattress Topper be cut to size? With a sharp razor knife perhaps?

    • This was the BEST memory foam I have purchased, been trying to find others like it, but had to return all because none beat the comfort like this and I was well rested every night, which is a surprise to me! the size queen for me queen bed did not fit pperfect, but---oh well. I don't know if you can cut or if it will mess up the quality. Sorry. I have heard others have cut theirs to fit.

    • Unfortunately we don't recommend that you cut the memory foam mattress. Please let me know if you have any further question.

    • Not sure, I wouldn't. Love mine and friends from Ohio bought two of them and this year bought my mama one for her bed. All do Love this foam.

    • We did wind up cutting it and it's just fine. We sleep on the mattress every night and it does not show any unusual signs of wear as time passes. Thank you for your reply!

    • I have cut old ones and new ones, made pillows for all of the family and never had a problem. This may sound funny but, the best thing to cut with is the electric carving knife we use on our turkey!! Sclices thru like butter. WE even made our dogs ther own memory foam beds.

  • What is the lifespan(warranty) estimated for this product?

  • Can I put this topper on any style mattress or just another memory foam mattress?

    • This item is designed for memory foam mattresses, but it should also fit on other types of mattresses. You might also consider purchasing a pad or an encasement for your regular mattress.

  • How can I order a cover for the queen size Serta Rejuvenator Dual-layer 4-inch Memory Foam Mattress Topper?

    • Although they make covers just for the memory foam topper, in our experience the mattress pads with elasticized skirts are much better at protecting the foam and keeping it in place on the bed as well. Our suggestion is item number 11756722 or item number 11276456. If you want a cover for just the foam, we have a down alternative version as item number 1016039. That is the only cover we have in stock.

  • If you select a king topper, will the pillows be king size too?

    • Unfortunately, if you select a king topper, the pillows will still be a standard size (18 by 24 inches).
