My husband and I tested out mattresses in a furniture store because I was curious if our bed is the cause of back pain we both have. We fell in love with the Tempur Pedic mattress but I was against buying it, because we just got our current one, plus a new bed frame. It was so tempting but we passed. Our mattress is a firm hybrid barely a year old. I didn’t realize how firm it was until we tested others out. Then I had the idea to see if they had toppers and found this one! It hasn’t been 24 hours yet for it to fully expand but we both love it so far. My husband has the idea to get a 2nd one to double it though. He wants it thicker to feel like the actual bed. I’m satisfied with it however the adjustable bed frame would’ve been amazing. It’s super soft and curves to the body. I sleep on my side mostly but turn on my back. Cooling works and it definitely relives some pain and pressure from my lower back.

I have a queen size "firm" posturepedic Plus Hybrid Sealy mattress and although it's an excellent mattress, I still experienced some loss in circulation and pressure on my hips and shoulders as a side sleeper. I had been planning on buying this mattress topper for about a month before purchasing. I watched a video of someone reviewing it outside of Amazon and I'd like to share some notes he stated that are true to this topper. If you want to watch that video, look up "Tempur adapt mattress topper review - the best pressure relief?" by Mattress Clarity. The video as of writing this review is 5 years old. For reference, I am 5'6", 107lbs and I'm bony. I sleep on my side but sometimes roll over onto my back during the night. I have osteoarthritis in my left hip and I've had a history of cervical nerve issues, which makes my left arm numb when I sleep wrong. Your mattress underneath has to be firm because this topper is SOFT. You probably don't want to be trapped inside your mattress if it's too soft. If your mattress is, for instance, 8 out of 10 on the firmness scale (10 being closer to that of a tabletop), then this topper will reduce that number to around 5. My mattress is soft in comparison to other brands, so there was a concern that this topper would make my bed too soft, but that hasn't been the case. When I first put this on top of my mattress, I was concerned my hips and especially my shoulders would poke through the foam and be touching the mattress. It might be two inches thick but I haven't actually done that. I'm well-padded. The softness is perfect for me. It did take a few nights for my body to adjust, as I was still waking up with sore hips, but after a month of sleeping on this combo, I wake up refreshed. I was concerned that I'd maybe need the 3 inch topper instead, but the 2 inches work perfectly fine. Maybe in the future when I might wear this one out, I'll get the 3inch. But for now, this works. I also love how, like the tempur-pedic mattress, it's motion isolating. I wouldn't trust that a glass of wine wouldn't topple over, like they used to demonstrate in old tempur-pedic commercials, because my Sealy mattress is a bit springy. So if you're expecting this to be perfectly motion isolating, I think it largely depends on your mattress. If you were like me and were concerned that this topper might shift around without mattress straps, it's ok because mine hasn't budged. However, I do not flop around much while I sleep, so I'm not sure if a flopper would experience the same thing I have been. The box came with a nice fitted sheet that keeps it in place. But for me, this topper has so much grip, I struggled getting it onto my mattress because it decided it didn't want to move. I would recommend someone else help you, especially if you have a queen or larger. But it is doable solo. Speaking of the fitted sheet it came with, you might want to look into replacing the fitted sheet you already have with something with deeper pockets because this topper does heighten your bed. Deeper pockets or size up, like from queen to king. There is minimal smell right out of the package. I didn't mind it at all. I couldn't immediately access my package when it arrived. So this topper was sitting in its packaging for several days. I was worried it wouldn't decompress. Luckily, it decompressed almost immediately by itself. I didn't need to do anything for it to spring into working order. As for my medical issues, I experienced some arthritic pain at first, but that slowly disappeared. I've had zero issues with my cervical nerve to the point where I forget I even have that issue. I would recommend this tempur-pedic mattress topper to those who have similar features to me and for side sleepers. Larger builds will benefit from this as well, but if you're bigger, I'd suggest watching that video because the guy reviewing it is a bigger guy. Update (April 19 2025): Tempurpedic foam, I've learned, makes you sweaty at night. I haven't really stopped sweating with this topper. I am normally a cold sleeper, so this surprised me. Also, it did shift a little bit and it's hard to move it back in place, so I've kept it where it decided to sit. The comfort of this item is too precious for me to get rid of it, that being said.

Bought a pricey firm mattress from S&Fs thinking it would increase the rigidness of the springs, not make the pillow top more firm. I was wrong and It was super uncomfortable, but put this on top and it’s actually pretty nice. A little soft for my taste, but it’s held up for over a year now and it’s a huge improvement over the mattress without it. Tried taking it off after a year and the mattress was still not comfortable without it. Not a big fan of the straps that keep it on either. They could definitely be designed better, but they work. If it was cheaper it would get 5 stars; but at this price point there are some improvements I’d want.

I bought a $3500 Tempurpedic "Cloud Supreme" mattress about 6 years ago when I was having serious hip pain. The relief it brought was miraculous. But, after roughly two years, that same mattress began to sag in a most unpleasant way. Sleeping in the deep "canyons" created by the foam giving way made my sleeping hellish - or more accurately - way too hot. Now I have more arthritis in my hips and my shoulders and found myself with a problem. I detested sleeping on the mattress and wanted a new one, but the thought of an innerspring mattress' springs pushing back up on my pain points was too much to bear. And there was no way I was ever going to spend $3500. on another Tempurpedic that would probably last me only another two years. So I suffered and frankly, was too anxious to try anything else - even the new hybrids - part foam & gel, part springs. Finally, I couldn't take it anymore and decided to buy a mattress from an online company that really will take back a mattress that doesn't work out - they don't have a business without that perk. I ordered one with a Euro pillow top because I like a softer bed. I would classify the mattress as a "light hybrid." Turned out that what the mattress manufacturer considered "soft" and I considered "soft" were about as far apart as can be. But, I decided that since I had a few months to try it out, I would try some "topper-like" modifications. I tried a few things we have around the house and got close, but nothing quite worked out. Despite my "falling out" with all things Tempurpedic, I could still recall how miraculous the mattress was the first two years I owned it - it MILDLY conformed to my body then (no disappearing halfway into it). The sleeping was excellent and without pain. There really IS something to the idea that metal springs can and do push pressure back up into parts of your body and causing pain. So, I decided to give this topper a try - $300 definitely is more affordable than $3500. The topper brought me back to the feeling that I was sort of "skimming" the bed. The arthritis pain was disappearing. I've never cared for the "conforming" feeling of any Tempurpedic product. Also, truthfully, I LOATHE the absolute flatness of the top of Tempurpedic products. Perhaps I am too "old school," but I like a layer of soft and pillowy next to my body. Tempurpedic never worked for me in that way. At that point, with my pain gone with the new mattress and the TempTopper, it occured to me that I could try a topper on top of the 3" Tempurpedic topper (for the record, "toppers" of any kind DO NOT work well with a Tempurpedic mattress - especially if you have pain). So I spent hours reading here on Amazon looking for the right pillowy softness for my topper's topper! I needed the right height, the right fabric and a texture on top that showed and felt "pillowy" through my sheets. I had left that absolutely flat Tempurpedic mattress top in the past - along with it's ridiculously sinking hot hole. Luckily, I found the right topper to suit my sleep needs. So I feel great. The new mattress I bought cost less than half of the disastrous $3500 Tempurpedic Cloud Supreme. The Tempurpedic 3" topper ($300) took care of the pain caused by "springs pushing into my hips and shoulders." The "pillow topper" was less than $100 and takes care of making my sleeping experience comfortable and plush. The best part? As I see it, the only thing that <may> go wrong with this new "configuration" is the Tempurpedic topper perhaps getting a little too soft years down the road. It's only 3 inches high. How much could I really sink? And if I do eventually, I can live much easier replacing a $300 piece of foam than a $3500. mattress for the exact same amount of pain relief. I am a HAPPY CAMPER!

I have owned several 3” Queen mattress toppers over the years due to back problems. In 2020, I invested in the 3” Tempur-Pedic TEMPUR-Supreme. It was expensive, but it was worth every penny. Its comfort, support, and quality were excellent. At the beginning of 2026, it started to deteriorate, and cracks began to appear in the foam. I contacted Tempur-Pedic to file a warranty claim, but because the topper had some stains around the edges from normal use after several years, the manufacturer used that as an excuse to deny the warranty. Despite the bad experience with Tempur-Pedic’s customer service, I decided to purchase the same model again because the original had been excellent. I even bought a waterproof protector to prevent them from denying another warranty claim in the future for the same reason. To my surprise, the topper I received was not the same product I had purchased in 2020. The foam was much lighter, felt considerably less dense, and the quality was clearly inferior. I checked the labels and found an important difference: the 2020 model stated “viscoelastic polyurethane,” while the 2026 model only states “polyurethane.” Because of that difference in quality, I decided to return it immediately for a refund. It is far too expensive a product to offer a quality that is much lower than it was just a few years ago. My recommendation is to protect your money and also consider other brands.

We purchased a tempurpedic mattress about 6 months ago. I chose medium firmness. I was trying to get used to it for months until my return window was closed. I hated that mattress and how it had zero relief on all my pressure points! This topper is a 100% life changer!!!! I do not dread going to bed any longer! It is beyond comfortable! I am melting into the bed and I love it!!! It feels like a warm hug every time I toss or turn! Highly recommend!!! I wish I bought it sooner! Perfect thickness! My dogs love it too ;)

UPDATE: 02/13/2021 I've had this Tempur 3" mattress topper for a little over three years now and even though it's slept on nightly (and I think sometimes during the day when I'm out my dog jumps up for a nap! LOL) it still looks and feels brand new. I totally recommend it! ___________________________ ORIGINAL REVIEW: FEB 2018 I ordered this in late November 2017, and received it shortly thereafter, but instead of leaving a review for it right away based on my initial impression, I decided to give it some time - sleep on it, so to speak. LOL And wow does it sleep good! My initial impression was 5 stars from the moment I pulled it from its box, and nothing has changed for me to reduce that. While I would love to be able to afford the full TempurPedic mattress, they're just not in my budget, so when I saw this topper was available from the same company, it seemed like a safe bet that it was going to be the quality I'd expect but at a more attractive price. It is being used as a topper for a relatively new mattress that is still in fine shape (no sagging, etc) - one of the "S" brands, though I don't recall which, off-hand. Tempur didn't skimp like some of the less-expensive topper brands available; it is a full and dense 3", and meets all corners of my full size mattress underneath, giving the bed clean lines when made. It doesn't bunch up during sleep (like the cheaper store-bought "memory foam" topper it replaced), and it fully returns to its original smooth flat surface within seconds of removing weight. The cover is very nice, and washes easily, but is slightly challenging for one person to put back on only due to size and weight of actual topper pad; it takes a minute to slide it on like a pillowcase, just needing to go a little at a time from each side until its all the way back on. But the best part is how it sleeps... and how I sleep because of it. Exactly as expected, upon laying on it, it slowly starts to mold itself to me until there are no discernible pressure points - and that's the beauty of *real* memory foam, which is what to expect from Tempur. Often times, I wake up in the morning in the exact same place and position I laid down in the night before, meaning I slept the whole night through without shifting around trying to relieve uncomfortable pressure points, and well, because there aren't any. As for its sleeping temperature, it doesn't seem to 'heat up', or extract body heat, for that matter, and I use it in a non air-conditioned house in the Caribbean. It took a few nights to get used to it at first, mostly because I was so used to being uncomfortable during sleep prior to it that it felt weird to actually be comfortable. Now, each morning, I wake up feeling like I actually slept. And that's a really nice feeling. Not trying to start any trouble, but I've read through most of the reviews here, and my guess would be that at least some of the poorer reviews are from those who are either trying to rejuvenate an already saggy, worn out mattress, or are just not familiar with the technology behind this type of pad. Putting this pad on an already sagging mattress is only going to accentuate the sag even more as the pad conforms to the body - it'll feel like sinking into a pit. It's going to need a stable and uniform underlying surface. And as for the technology that makes this type of memory foam desirable and unique, that absorbing/conforming to the body is exactly what it's supposed to do; that's the whole 'relieving pressure points' from earlier. It's not quite a weightless feeling, just a feeling like there are no specific spots on the body that feel uncomfortably digging in - it's complete full-body support because it molds itself to the body. For the moment, at three months in, I'm very pleased with this Tempur pad, and do expect that to continue throughout its 10 year warranty period. If anything changes regarding quality or comfort, I will update my review accordingly.

After taking in delivery of this item, I no longer believe that "you get what you pay for". Cheap doesn't always mean bad, and expensive doesn't always mean better. Tempurpedic charges outrageous prices despite cheaper competition because they can. Most name brand anything can charge what they want because they know the name alone is enough to sell their product. And while I don't know where Tempurpedic chooses to invest its profits, the one place they're clearly not focusing on is quality control. I had been looking to upgrade my comfortable, but old 2" memory foam topper. I decided I wanted to try a 3" topper instead because I felt like I sank right down to the mattress with 2". After reading countless reviews and comparing prices I decided to bite the bullet and try this one out. I have a super firm hybrid mattress that I love but it's just a bit too firm for me. I'm partial to memory foam toppers as long as they're high density; I hate foam that's too soft and feels like quicksand. When I received it the box was a little banged up, but not too bad. The mattress topper comes compressed and rolled up in plastic wrap. Upon removing the wrap, the topper immediately expands to its normal size. The cover comes pre-installed but I recommend removing it right away for two reasons: 1) it absorbed the off-gassing odor from the foam so it's worth washing right away (the off-gassing isn't the worst I've smelled, but it's definitely there) and 2) to check for defects in the foam. Honestly removing the cover is the only way to do a thorough inspection. As you can see from my photos, mine arrived with a significant tear. Right on the edge, and large enough to put my entire arm through. This tear was located right at the top of the topper and I would not have seen it without removing the cover. It arrived in this exact condition, and I was honestly shocked. There's no way this tear occurred in transit as all the packaging was intact. It MUST have occurred wherever these are packaged, and I wonder if they have a quality control department to inspect products prior to packaging them up. It's obvious from reading other reviews here that people have been receiving damaged products, whether it's the foam itself or the cover. It actually makes me seriously question whether Tempurpedic truly cares about quality, or if they're more focused on quantity. As for how comfortable it is, this is going to be very subjective. It's definitely a medium-firm as advertised, and I think it's extremely comfortable. However, my husband does not like it. We both like firmer sleeping surfaces so the reason I think I like it and he doesn't has to do with our body size. I'm a heavier person, and he's tall and skinny. Because I'm much bigger, I don't get completely sucked into the topper. I find it to be very supportive actually. But being a thinner person, it takes longer for him to sink and he sinks in too much. He finds it more difficult to get up out of it compared to me. We are actually considering cutting this topper in half so that I can have the Tempurpedic side and he can have the old topper we were using. I mean, the gigantic tear begins at the halfway mark so it's almost like the work is done for us. Thanks, I guess? Anyway if you decide to purchase this on Amazon, make sure that Amazon is the actual retailer and not a third party. That way if yours arrives damaged and you need to return it, they can arrange for a "large item" courier to pick it up since there's no getting it back in the box once it's opened. It's a great topper, but just make sure you're ready to deal with the hassle if it doesn't arrive in perfect condition. At this price point I expected quality, and what I received was damaged garbage.
