      I normally prefer a firmer mattress as I have back issues. I do tend to end up on my side during the night. My shoulders were starting to bother me. I wanted a mattress topper that wouldn't be too thick and bother my back, yet relieve the pain in my shoulders. Very happy with the decision to go with this topper.

      We were having some problems with our mattress and decided to purchase a mattress topper. It was very comfortable. It's really heavy though and hard to move once you get it on the bed. But it made a big difference in our mattress and we definitely slept better.

      I bought this to add to the queen size bed in our Airstream travel trailer. RV beds are notoriously uncomforable but this really did the trick. Now it is as comfortable as my bed at home.

      This memory foam mattress topper is so soft and comfy. The only "issue" i found with it is that I needed to get sheets with deep pockets to account for the added height with this topper.

      IF THIS POST IS TOO LONG, SIMPLY READ THIS FIRST PORTION:IMPORTANT INFORMATION:A mattress of 3? thickness with 3lb density is wonderful for light-average individuals and will provide the comfort/support needed (approx 100-150lbs).A mattress of 3? thickness with 4lb density is ideal for light ? above average individuals, 100-200lbs.A mattress of 4? thickness with 3lb density is ONLY suitable for light individuals, or those who require a very soft mattress. If you are over 150lbs you will begin to lose needed support. If you are over 200lbs this will not provide you with the support you require and may not be appropriate for you.A mattress of 4? thickness with 4lb density is suitable for average ? husky individuals, 150-250 lbs. The extra inch (over 3?) will give you the extra needed cushion so that you don?t sink straight through the mattress and the 4lb density will provide you with the much needed support. </BR> ------------------------------------------------------ I spent a great deal of time doing research on memory foam toppers before deciding to make a purchase. I'm a very meticulous person and I like to evaluate all of my options before selecting an item, specially one over a certain price, and if I would consider it a luxury item.First off, I want to say that I have nothing but praise for this memory foam, and I will attempt to aid any person reading this in deciding whether or not this is the correct item for them.When looking at memory toppers, if you are looking for both comfort AND support, then you should automatically eliminate anything with a depth of 2.5" or lower and 5.5" and higher. (Do not choose 2.5 < or > 5.5).A thin mattress topper of below 2.5" may provide you with a comfortable feeling, but it will not provide you with the actual support you need, if you are only looking for comfort, and not physical benefit/support, then below 2.5" is for you. One caveat to this is if this mattress topper is intended for a child or very light individual, they will depress the visco-elastic material less then a (older) teenager or full grown adult, in that circumstance a mattress topper of 2.5" will be supportive/beneficial.A thick mattress topper at/over 5.5" will be quite deep and you will find that you sink into the mattress (unless you are a child or an extremely light person, below or at 100 pounds, at which point your body will not sink, but you still will not receive the appropriate support for your body). For an average weight adult, you will not find the comfort you want as your movements will be restricted and support will now become uneven as the heavier parts of your body will sink too low and you will be unable to achieve the spinal/body support that is required for a healthy nights rest.------------------------------------------------------The optimal range for thickness of a memory foam mattress is 3? - 4". This range will accommodate the standard adult build (greater then 100lbs and less then 250lbs or approximately 45kg ? 115kg, these figures are products of my own analysis and consumer reports).-If you are a light-average build, 100 ? 200 pounds, you will likely find the comfort/support you require from a 3? thick topper.-If you are average-husky, 150-250 pounds, then you should review a 4? topper to accommodate for ?sinking? into the topper.There is an overlap of 50 pounds in the weight range(s), this is on purpose as you must consider that this topper may not be used by only you, but a significant other as well.*I personally weigh 175lbs, whereas my fiancée rings in between 100-108lbs (please don?t tell her I posted her weight, hahaha). We found that the 3? topper provided excellent support/comfort for our weight ranges and have had nothing but approving responses from friends/families over the comfort of our mattress.---------------------------------------------------------Density is the second factor you must consider.3lb and 4lb is optimal density for the average consumer, someone weighting 100 ? 250 lbs and the density you require will differ based on size, obviously, the more you weigh the greater the density you will need.Avoid exceeding 5lb density as you will begin to sacrifice comfort in the memory foam topper. 5lb density is suitable for husky ? ?large? build individuals 250+ lbs, you would also look at a thicker mattress 4-5? in that weight range.---------------------------------------------------------Brand names: They actually matter for this product! Non-brand name foam mattresses have an indeterminable length of usability for their product. After reviewing an incredible amount of products from different suppliers I have found some of these products are meant to only last 1 ? 2 years, while others can last 5, 10, or 15 years. More often then not, the name brand products last longer. is fortunate that it has a large selection of quality toppers.----------------------------------------------------------Heat Distribution: As this mattress is not a ?vented? mattress it will trap heat a little more then an ordinary mattress topper. I have been using this on warm nights and have not found any discomfort from this small amount of added heat, in fact, as the mattress is able to retain my heat, it softens up a little more the longer I am resting on it, making my rest more on more comfortable as I lay there.----------------------------------------------------------If your partner happens to be a wrestles individual or someone who practically jumps into bed at night, then this mattress topper will help reduce the vibrations you feel and will allow you to sleep better without being disturbed. I speak as a perpetrator of literally ?jumping? into bed every night.-----------------------------------------------------------Washing/Cleaning:Good luck. Don?t get it dirty in the first place! Use a damp rag to wipe off any spills that may get into it. Never lay it directly on your floor (especially carpet), it will grab EVERY piece of dirt/filth there is and you will NEVER get it out.?oops------------------------------------------------------------------Personal Opinion:Overall I couldn?t be happier with my purchase. I haven?t slept this well in years! I have been having a very bad problem with being unable to wake up in the morning for the past few years. I have 3 alarm clocks (yes, 3 individual alarm clocks, 2 of them with 2 separate alarms, so 5 alarms), my cell phone with 3 alarms, and my computer with a morning alarm. In total, 9 alarms go off in the morning, and I have a tendancy of sleeping through ALL of them, even when they are at full blast. I had not been getting a real rest when I slept! To make matters worse, my partner moves around a lot, as such, I haven?t been getting a really good deep sleep in years, with minimal REM cycles?(dreams)?I have been exhausted constantly. All of that changed when I slept on this topper. For the first time in 4 years I am having vivid dreams that I remember when I wake up, this is an indication of a deep sleep, which your body/brain needs to recharge! Additionally, I wake up immediately at the sound of just one alarm at half volume! As I?m no longer thoroughly exhausted I can actually get up in mornings and have been making it on time to all of my appointments, and scheduled events! I can?t believe how much the memory foam changed my life!Do yourself a favor and BUY IT!------------------------------------------------------------------------*1 last note, when the package arrives, OPEN IT IMMEDIATELY and let it decompress/air out. Ours took only 1 hour to fully decompress as it was only in shipping for a few days. The majority of the smell left after a few hours and wasn?t bad to begin with. The odor completely left after 2 days, but was mild enough that we slept on it with no complaint the very first night we received it.

    • This pad has been a lifesaver!!!
      Verified Purchase

      I didn't realize that the mattress on the guest bed really wasn't that comfortable (never was - not that old) until I decided to test it. Priced new mattresses and decided that a topper was the way to go. I already knew that the foam had to be at least 3" think to mean anything and I knew about density. This wasn't a task for store to store shopping; company was on the way the next weekend. Zipped over to the website and did a bit of searching and there it was. The right thickness and good density. The shipping speed was AWESOME! These pads need time to unroll ON THEIR OWN. And a bit of time to air. You have to have a mattress cover which is deep enough to accommodate both the foam topper (this is really a bit more than a topper) and the mattress. (Ordered that from as well) I placed the pad on top of the mattress and let it do its thing. The next day it had completely unrolled and I was able to make the bed. Lay down and was amazed. It wasn't the same mattress. Be advised, without a cover which some do come with for quite a bit more $$$, it isn't a pretty sight. Since you're going to want a cover anyway, it really doesn't matter. This 3" memory foam topper/pad is fantastic. I stopped writing in order to lie down on it just for the sake of this review (Ah, the sacrifices we make) and it felt even better for my spine/neck than I remembered. And yes, my guests did appreciate the new feel - they'd slept on the bed before. I already know that I will have several good years for the guest bed now. An excellent value!

    • Excellent Value!
      Verified Purchase

      This Serta topper is a great value. I previously owned a no-name 2" topper with 2.5 pound density. This Serta from Overstock is 3" with 4 pound density, and the difference is wonderful! The 4 pounds offers firmer support, and with 3 inches it offers more of that support. I can tell the difference. I sleep better and wake up with no aches or pains. I have also priced these on the internet, and overstock has the best price on this product by far! Don't pass this up!

    • My Achy Breaky Body
      Verified Purchase

      I had been wanting to buy one of these mattresses for a long time but would only do so when I found one for approximately $100 and at least 3 inches thick. We got this, it arrived in a timely manner and weighs more than you think (lift with your knees). Once opened, it needed to be aired out as it is rather smelly but just letting it breathe for a few hours did the trick. We noticed that it arrived with a couple of nicks (sp?) in it but they were small, so we didn't bother making a big deal over it as a sheet would be on top of it anyway. Well, we loved it for the first 3 weeks before the foam started softening up where our body naturally lies each night. I love the mattress but my husband doesn't nor does he get a good night sleep like i do. The topper is now waiting to be given away. If either you or your partner like firm mattresses, don't bother wasting your money on this, however, if you are like me, and like softer mattresses, you WILL love this and the quality is pretty good

    • Love it!!!
      Verified Purchase

      I purchased this topper after having bought a brand new mattress that I hated and couldn't return! The first mattress I bought was too soft and I was allowed one exchange. I *thought* I was choosing carefully, but the mattress ended up being way too hard. I gave it some time so my body would adjust, but nothing. I was not sleeping at all, in pain, frustrated to the point of tears....and left feeling like I had just thrown $1,100 away. I bought this topper and it completely saved me!! I read the great reviews, but did not expect it to make this much of a difference. I took it out of the box and let it unfold on it's own as it says on the instructions. I let it air out like that in a sparebedroom for about 2 days. The smell went away soon enough. It fits perfectly on my queen bed and now.....I actually love my bed!!!! Also, I had mentioned the purchase to a friend of mine and he said he had also bought it sometime ago from Overstock and swears by it! Also, bought one for his parents.

I will be putting it on top of my hard mattress to sleep on.. I do not want to pile hard on hard so I would like to get something softer. I am both a stomach and side sleeper. I don't sleep on my back because I have a bad lower back due to a damaged nerve. My weight goes up and down between 170 and 190 lbs. Also is there anyone out there that has purchase this and had it for a good long time? I would like to know the approximate durability as I cannot afford to buy one every few years. I would like it to last at least 5 yrs. Any help any one can give me is truly appreciated. Thank you."

      • A:

        I've purchased this brand Serta 3" memory foam for all of my beds for the last ten years or so. I can't sleep without them because ALL beds are too hard for me...with this topper you will have no more sore back, hips, shoulders or elbows. It is soft without being so soft that you sink into the topper. Don't buy any other brand from anywhere will be happy with this one!!! My sis bought a memory foam mattress, too, and then had to order this topper....was also too hard for them. I have a Sleep Number with Serta Topper.

      • A:

        I have a herniated disc in my back so I bought this topper. I like it - it's not too hard and not too soft (sounds like a fairy tale). Is my back okay? Most of the time it is, but I also do daily exercises recommended by a physical therapist and I try not to move too much heavy furniture or flip mattresses.

    • Q:

      "Is this visco elastic too foam"

      • A:

        It was for me, I gave it away

    • Q:

      "I'm concerned about buying the King size topper for my King size mattress. A King size mattress is 76" W x 80" L, but this topper is 4 inches smaller in length and width at 72" W x 76" L. Will this truly fit a King size mattress correctly?"

      • A:

        I have purchased multiple memory foam toppers and have never had one fit exactly on any mattress (even when the dimensions claim it will). This one was purchased for my rv and is 4 inches to big in width and length but isn't too much of a problem. I have learned that even if the topper is a few inches bigger or smaller it doesn't seem to make much difference other then in the looks dept. If you want a mattress topper to fit perfectly then you can find one that's a big bigger (maybe a California king size) and then cut a few inches off yourself.

    • Q:

      "The specs say the regular King is 72" X 78". Is this correct because that is not the average size of a regular king size mattress."

      • A:

        Yes. The foam mattress is slightly smaller than the actual mattress.

    • Q:

      " we have a king size bed it's a little too firm I need a Topper my husband's about 265 and I'm probably 165 if that he would like to know your suggestion will there be a 3-inch topper or a 4-inch topper"

      • A:

        I don't really have any experience with toppers. Mine is a serta which I believe is a better quality than some. There is only me on a queen size bed and wt is 150 or a little less. With me it was a love come softly but absolutely love it. I would think that a 4 inch may serve you better with your wts. I would be sure and rotate your mattress. I have a good deep mattress and newer that you doesn't flip over but you rotate at least every 6 months . Good luck with whichever one you choose.

      • A:

        we put a 4 inch topper on ours, my husband and a big man and almost 300 lbs....this worked great for us.....on of the tricks to making a topper last long is to turn it 45 degrees about every two weeks and flip it every few months. this topper is heavy and does not move like a lot of toppers, and i have had ALOT of others before finding this one.

    • Q:

      "What is the density of the foam?"

      • A:

        3.5 pound per the Specs listed on Overstock. It is a nice dense topper.

        Great quality on density. Soft comfort with good support.

    • Q:

      "can you use it on a sleep number bed? "

      • A:

        You can place this mattress on any standard box spring or well ventilated platform. If slats are used, they need to be no more than six inches apart.

    • Q:

      "Could I use this on a sleeper sofa and allow it to remain on the bed when the bed is folded up?"

      • A:

        No it's too thick and heavy. It would make the sofa extremely comfortable !

        Yes you can I bought a 4" and it's fine, folds in perfectly.

    • Q:

      "Is this mattress topper with a washable outer cover?"

      • A:

        No, this topper does not have a cover.

    • Q:

      "Is this mattress Certi-PUR US certified? Is it made of Plant Based material or the traditional way? "

      • A:

        All of our foam is CertiPur certified and is petroleum based, not plant based.

    • Q:

      "I'm concerned about how much heat this topper absorbs. I've read reviews about other toppers and people say they tend to get very hot during the night. I tend to sweat at night. Does this particular topper absorb a lot of heat? Will I get vey hot at night?"

      • A:

        Memory foam does response to temperature, thus making it warmer. You may want to try a gel memory foam. The gel makes the topper more supportive and will keep the topper cooler for longer. This is probably your style if you want the comfort of memory foam with a little extra support and without the extra heat retention. You can locate this by searching "gel memory" foam from the search bar at the top of the homepage.

      • A:

        I get hot with the topper but my husband says he's comfortable. When we buy our new mattress we're just going to get one with a gel topper.

      • A:

        Hello Sarah S., when comparing this item item to ITEM# 1010297 (Serta Deluxe 2-inch Memory Foam Mattress Topper), the differnce is the thickness and warranties available for each item. Please feel free to contact us again with any further questions. Thank you for shopping with us!

    • Q:

      "how much does this weigh?"

      • A:

        Hello stroboscopic, the twin topper weighs approximately 20.3 pounds, the full size topper weighs approximately 26.6 pounds, the queen size topper weighs approximately 32.4 pounds, the CA king weighs approximately 39.2 pounds and the king size topper weighs approximately 35 pounds. I hope this info helps. Thanks for shopping with us!

    • Q:

      "Can I still use the same queen size sheets to cover the topper and my mattress?"

      • A:

        Hello katchimney, we appreciate your inquiry. The topper will compress somewhat, however, if your sheets are already fairly snug, then it may be difficult to put your existing sheets on; deep pocketed sheets would likely fit better. Thank you for shopping with us!

      "I have two twin mattresses together to form a king but they are only 75 inches long. What size topper should I buy?"

      • A:

        Hello mufasa9601. 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. Please let us know if you have any further questions.

      • A:

        Is this Certi-pur US certified? I know some of Serta's products are. I'm searching for a non-toxic mattress topper ideally made with plant based material rather than traditionally composed *
