    • Islandrosie

      I like this. Yes, it is warm, but it is very comfortable. One issue: in one corner there is a place where the visco foam is gurried, looks like it did not foam properly, sort of a melted look. We just put that corner at the foot of the bed. The size is perfect.

    • Sleeping on a Cloud!

      OK - Was trying to satisfy the man in my life - 6'4" and 210 pounds - with a comfortable transition from our very comfortable Queen mattress to a King bed with a FIRM mattress... so I bought this topper and installed it on top of the FIRM mattress! Yep - This topper is the ticket! He installed the TV on the wall in the bedroom and laid down on the bed afterwards to check the TV angle...and said Oh My This feels good...and he didn't move until he was called away for work! I'd buy it and recommend it highly!

    • Deep and dense

      I have memory foam mattress, but my grand-dog ate a crater into the top layer. Flipping a memory foam mattress is not an option. So I filled the crater with the shredded foam and sealed if by placing this topper over the mattress. It is heavy and dense enough to solve the problem and the resulting "mattress" is unbelievably plush. It does have a tendency to shift and requires "re entering" when it's time to change the linens.

    • Turns any mattress into a dream of pleasure!

      I purchased this 4" memory foam mattress topper as a last effort to find something that would help me sleep better. I have been fighting a few horrible disease's called Fibromyalgia and Rheumatoid Arthristis and Chronic Fatigue for years and have never slept through the night. I'm only 44yrs old and too young to feel so old. The first time I put on my memory foam topper, I just layed there with no pain and instant relief. I didn't even get into my pajamas; because I fell asleep within minutes and to my amazement, slept all night long in the same postion. I woke up in complete shock and actually for the first time could walk to the bathroom without feeling stiff and bouncing off my furniture to just hold me up because of the pain. There's not a prescription from any of my doctor's that could have provided me with such relief. Now my condition is getting so much better because I am actually sleeping through all four stages of sleep that your body needs to repair your muscles, ligaments, tendons, not to mention your state of well being from having a great night sleep! I highly recommend this topper to everyone, especially people who suffer from insomnia caused by pain that awakens you when ever you move at night. With this topper, I find that I do not move. This is the best investment which was so cost effective, I could have ever purchased. There's not a sleeping pill in the world that can out do this topper! Thank You Overstock for saving my life. I was at a very low time in my life from suffering such chronic pain day and night. A good nights sleep keeps pain at bay during the day. WOW...what a dream come true. Sincerely, Carolyn

    • I swear by this!

      I were a bit skeptical to buy this topper as I know like all of you out there, a good night sleep is priceless... was just thinking of getting rid of my mattress which is still in mid condition and got one of those Tempur Medic mattress instead...Last minutes, I have decided to try this one out first...... oh my Gosh, it was so very comfortable..& .how good was it???? I almost missed work this morning and it is just not so me to do that... My advice, spend monies to buy this first if you are thinking about replacing your mattress... it is really really Great for a fraction of what could cost you..and it is made by Serta...can't go wrong with that.. Please note of one thing, the instruction of how to open this topper was packed in the bottom of the box, so I tried to manually rolled the topper opened and Opps, it was a mistake...I did open it, but it took a lot of of me to do so.... Please do not attempt to do that, just open the topper from its wrapper and let it sit on the floor for at leasat 24hour to air out the smell, but also make it easier to roll it open later. One happy and repeat customer...

    • good for its value

      I wasnt going to review this product until I had it for a while. 1 year later, here's my review: PROS: - with memory foam pads, the thicker, the better. 4" is the thickkest ive seen available out there. - decently priced. you get what you pay for - never woke up with a bad back, also considering i sleep on my side and chest - i sleep longer CONS: - it is heat sensitive: if it's cold in the room, it's firmer, if it's hot, it's softer and it's no longer a "memory foam" but a regular foam. - with that said, the area/shape you sleep on is not really a "memory foam" because of warm body temperature - the more it is exposed to the air (especially the edges), the foam turns from white to yellow like the rest of the regular foams - it's about 2" short from regular mattress size. but i suppose that's to make room for the fitted sheet to cover the mattress and the extra 4" thick memory foam. - im about 120lbs, the firmness is perfect. but i dont know about those heavier than me, because like i said about the heat/temperature problem, you might find your self sinking down making it a bit uncomfortable in the summer.

    • The future is now..

      Let me start by saying I am a real person. A co worker began talking about his $3K "T-Pedic" bed and really piqued my curiosity. I have a Latex bed and have been happy with it for some time. Well, I stumbled onto Overstocks' memory foam section and saw the 1400+ positive reviews on this 4" topper so I decided to see what all the gushing was about. Let me tell you what you can expect from this product. I ordered the topper on Sunday and it arrived on Friday. For only $3 shipping charge, that is really good. I am very happy with the Overstock shipping. I got a tracking number and could follow the package from manufacturer to my home. I read that some people had rips or stains on their toppers. Mine arrived just fine thru DHL. And I was pleasantly surprised that it had almost no smell. I mean there was a "new" plastic smell, but not anywhere to the point of getting nauseus. Maybe the 5 day trip let the product breath and air out before I got it. But I must admit, the first night my wife and I had to put 3 layers of sheets to not smell the pad when your laying on it. Also I noticed that the manufacturer was Advanced Urethane Technology (even tho it is sold with a serta label), so maybe the quality control issues have been addressed by Serta using this new company. So I drag the box to the master bedroom, and open the box and pull out the foam. It was rolled like a burrito . I centered it on the mattress and took off the plastic covering. As soon as it began to breath, it expanded, Fast. It took less than 10 minutes to fully expand. I did not Force it open. This is where I think most people put tears in their toppers. Moving the foam before there is air in the cell structure is a recipe for disaster. Once fully expanded, the Topper was not as heavy as I though it would be. It is a little tacky, so if you pull it with force, it "could" rip, but just don't pull it. I was easily able to just "lift and push" it into place. Oh and I'm happy to report that the King size really does fit our King bed. Maybe an inch off, but nothing to complain about esp. when i was reading some horror story reviews of 3 inch short toppers. Another thing I am happy to report, is that the topper isn't snow white, but pretty close. So it doesn't look unsightly. But you will be buying a cover for it anyway so what does it matter. So it's unpacked, centered, and expanded, now for a test. WOW. Now this is comfortable! I am happy to tell you that I am convinced that we are in a new era in sleep technology. I know it sounds corny, but I couldn't believe how nice it was. I would compare it to a feather bed but WITH support, or several layers of down comforters that don't squash when laying on it. The thing is, these pads are only going to get better than they are now. I made the bed and did the wife test. She loves it! I surprised her as she didn't know it was on our bed till I told her to lay down. And I know this is going to sound repetitive, but it's true, not 10 minutes after laying down, she was fast asleep! No lie! I was next to her and I just couldn't help but laugh because I had read reviews where the same thing happened to others. It's that comfortable! Ok, so now for some nitty gritty. You do have to adjust to it. It took me and my wife 1 night. It's mostly a mental adjustment more than anything. You just have to move different, and realize that you will be comfortable in one or 2 positions the whole night. My wife and I are back and side sleepers. But you almost get into a routine because your body gets numb or hurts every hour or so on a plain mattress, well no longer. The only time I roll over now, is for breathing reasons, namely if I snore too loud on my back, I'll move to my side, or my wife will move me. :) But once I'm there, I'm done. We are both sleeping more deeply and feel so good, we honestly can't believe it. I can say with honesty that all pressure is alleviated on this topper. No more pinched hips or bad circulation in the arms or shoulders. No more aches, stiffness, or soreness. We simply love this memory foam. Now I do have some advice for those out there who need a more robust topper. This 4" topper is great even at 4lbs. density. But If I didn't have to share my bed , the 5 lbs. density would be my next purchase. These are the only 2 densities, you should ever spend your money on. less than 4lbs wont support body weight very well, and your frankly, just skimping on topper comfort and durability. And stay with either a 3" or 4" thickness. This extra inch helps but is not needed if you have a higher density. I had my wife laying on her back and side and did some measurements and found that even on her side she only used 2" inches of foam and even less at her shoulders (these 2 points are the heaviest). We then measured me (6 ft, 180lbs) and I only used a half inch more at both points. Plenty of margin left in the foam to compress. We then checked for spin alignment, and it was normal. The foam curved exactly to our bodies contours. I had to see this to believe it, but now I have and it's true. So we haven't had the hammock feel with our topper. But maybe it is because of our weight and mattress condition. If your petite, this 4" 4lbs. topper will be a perfect fit as my wife will attest. However, if your heavier, go for the 5lbs. density and if that is too firm, then 4lbs is your answer, or vice-versa. Once your have adapted to how to move on this memory foam, you will love it. The real key is to just use your legs. If your on your back, just bring one knee up and push your foot down, viola! Your rolled over with no fuss or extra muscle needed. In the end, you should not think this topper will make a trash mattress good. It will still conform to the uneven, lumpy surface of your bottom mattress. But if you have a decent one but it's too hard, it will do miracles. For the price, you can't go wrong. Just be sure you don't want a denser topper first and you'll love it. Having this 4" memory foam topper has opened my eyes that $3K for memory foam bed is just a massive markup. You can have the same comfort with a decent mattress or platform bed and 1 of these dense (4or 5 lbs.) toppers for a fraction of the cost. A little reading and shopping will save you thousand$, don't you owe yourself a good nights sleep? This foam is fantastic!

    • Please tell me how the Serta Ultimate 4-inch Visco Memory Foam Mattress Topper compares to the twice as expensive Tempur-Pedic Tempur Topper?

      • Hello penelopeb, you will be contacted by Customer Care. Have a great day.

    • I am looking for a mattress to be used while traveling. Can the 4" pad be repacked? If so, what is an approximate size it can reduced to? Is there a designed bag or case for transporting it? Will it fit into a suitcase? Thanks for any help.

      • Hello gzusfreek, memory foam is not an easy item to be repacked. I would suggest using an Air Mattress, see Item 16402902. With an built-in pump makes it easy to inflate and deflate, great for traveling. Thank you for shopping with us.

    • What are the actual sizes of these toppers?

      • Hello PatriciaAnn1, the dimensions are listed in the product details, the twin is approximately 37"W x 72"L, the full is approximately 51"W x 72"L, the queen is approximately 58"W x 77"L, the king is approximately 76"W x 77"L, the california king is approximately 70"W x 80"L.

    • Why did you choose this product?

      • We purchased the Serta ultimate 4 inch visco memory foam mattress topper about 4 years ago and absolutely love sleeping on it. We're refreshing our bedding and think it's time for a new topper. Can hardly wait for it to arrive!

      • This will be number 7 of these mattresses for us. Three for ourselves and 4 for family and friends. All have been loved and cherished by its owner. They are: -A little smaller than a true queen in length and width, but true to size in depth. -The 4-pound density is just right. It feels like you are sleeping suspended in mid air. They do not fix a depression in your mattress. If you have a depression, you will be able to feel that. -Not hot -Smell of foam dissipates quickly -Last for years without losing shape or support I would recommend this product to anyone.

    • My Wife and i bought a brand New Serat King size mattress set from Rooms to Go in Seffner, Florida, less than 90 days ago. After our best efforts to "adjust" to our new bed", we are VERY dissatisfied with this mattress. It is NOT a pillowtop, which is what we wanted in the first place. We were "guided" to this model by the sales person. It is called a "ROCKWOOD PS'" on the Serta label tags. It already sags 1one inch on both sides and we were told by RTG's C/S it has to sag another 1/2 inch to be considered defective. And after their C/S man came out we were never called as to what happens next. We waited ten business days and then called them, and we got the standard party line. So while waiting for them to hopefully show up and remeasure our bed, we suffer. I wake up feeling stiff and have the bottom of my thighs and calves stiff and hurting very bad which I NEVER expierienced until I slept on this new mattress. My wife has leg pain as well. Rooms to go told us that All Sales are final, because we bought their product at their outlet store, which by the way is also their corporate HDQ. The store Mgr has not returned my wife's phone calls and Serta fliped us back and said it was RTG's problem. My question is this; Wou;d a PillowTop mattress top cover make this bed sleepable? We both sleep on our sides and backs. NOT our stomachs! We believed in RTG's reputation and the fact we were buying a NEW mattrress set, not scratched or dented piece of merchandise, that our purchase would be trweated like any other product purchasse ie., the customer's satisfaction is first and foremost. The outlet store (it is huge) is very close to our residence and we did not go there to get a better'deal". So, in conlusion will a pillowtop addition make the bed plush, and take away the rigid feeling?

      • Hi Butch LaRue, I am so sorry to hear of this issue you are having. With the current state of your mattress we can not guarantee results, but adding a soft to medium firm topper should provide some comfort and relief. Being side and stomach sleepers you need something a bit softer to conform more to your body and relieve pressure points. A topper would help until you can get a more permanent solution. I would also recommend not going lower than a 3 inch thick topper. Hope this helps! Sherri R.

    • What is the size of the box that the King size topper arrives in? I need the dimensions as I will be shipping it internationally.

      • Hello airmilt, the shipping dimensions of this is 16 inches h x 16 inches w x 32 inches l. I hope this information helps, have a great day!

      • It is about 3 feet in height and 1.3 feet in Depth & Width.

    • What is the shipping size and weight of this topper in King size? Also, does it come in the original vacuum sealed packaging?

      • Hello airmitt! This item does arrive in the original packing. This item has a shipping weight of 55 pounds. Thanks for shopping with us! -Amanda P

      • The shipping weight is 58 pounds that's printed on the UPS label. Yes it does come in a vaccum tight in a heavy duty plastic bag. Once you open it, it will start expanding by itself and resumes to its original shape immediately. You must lay it flat on the ground or on the king bed to be more effective.

    • Can the Serta Ultimate Mattress Topper adapt well to an existing Tempurpedic Mattress with respect to relieving morning back pain?

      • Hello allen99, this topper has received excellent reviews! This item can be used with a Tempurpedic mattress however, we cannot say whether or not it will be successful in relieving your back pain. We suggest that you consult with a physician for any recommendations. Thank you for shopping with us.

      • Hello allen99, per the product care information for your mattress, the manufacturer does not recommend using a memory foam topper in addition to your mattress, describing it as another "layer" between you and the material. I hope this information helps. Thanks for shopping with us!

      • This is very soft. For back pain would be better more firm and bounce. You soak in it like to a cloud.

      • I have this topper on top of my Tempurpedic and I love the additional comfort it provides. I found the Tempurpedic to unforgiving. This topper provides just the right amount of give for a awesome night sleep. I look forward to laying in my bed, it is that comfortable.

      • In my opinion this topper is ideal for people with hard mattress or old mattress, however if you using it on top of the Tempurpedic Mattress than you may not see that much of a difference because you will putting just an extra layer of softness of the memory foam on top of the memory foam. The Tempurpedic Mattress are precisely designed to contour to your body as they use the premium patented high quality like 7 pound density memory foam. unlike 4 pound density of the memory foam topper.

    • To Overstock: Could you please tell me where this 4-inch topper is made? It used to be made in the USA and the logo was included on the main description page. Two other Serta 4-inch toppers here at Overstock still show the Made in USA logo but this one does not. Our family and friends have bought at least seven of this 4-inch Visco Memory Foam topper because it was made in the USA. We all sleep better on it, but the latest purchase was about two or three years ago. We need a new one at our house after several years and are concerned because the Made in USA logo is no longer shown. If it's still USA made, will something that comes with the topper show that information? Thanks for your help!

      • Hello bjk626, this mattress topper is so comfortable! I am happy to say that this item is still made in the United States and the product will come with a tag that says so. I hope this information helps. Thank you for shopping with us.

      • Love this mattress topper! I love it so much I purchased two more for my kids.

      • The topper is made here in USA by Novafoam. The leading manufacturer of the memory foam mattress and topper for Costco. You will be happy with the quality as well as the warranty of the product. I have used their product for over 10 years and have been very happy with the quality and comfort.
