Description
Why memory foam? Memory foam is one of the most popular mattress materials for a reason. It contours to your body, absorbs movement, and delivers a personalized sleep experience that traditional spring mattresses can't replicate. Wrapped in a breathable knitted cover and anchored by a durable base foam, every layer is designed to work together for a better night's sleep from day one. Made for every type of sleeper Whether you're a side sleeper, back sleeper, or stomach sleeper, this mattress is designed to work with your body. Zinus' patented zoned pressure relief system means different areas of the mattress respond differently to weight and pressure, so you get the right balance of cushioning and support no matter how you sleep. Medium firm: the sweet spot Not too soft, not too stiff. The medium firm feel contours without sinking, supports without rigidity, and moves with you through the night. If you've struggled to find a firmness that works, medium firm is where most sleepers land. Safe for your family, certified by experts This mattress contains no fiberglass. The cover is OEKO-TEX® Standard 100 certified, tested for harmful substances, and all foams are CertiPUR-US® certified — meaning no formaldehyde, no mercury, no lead, and no ozone-depleting chemicals. The foams are also free from phthalates regulated by the U.S. Consumer Product Safety Commission, and screened for chemicals classified as carcinogens, mutagens, or reproductive toxins. The kind of verified safety standard you'd want in your primary bedroom. What keeps it fresh? Infused with green tea extract and purified charcoal, this mattress is designed to neutralize odors and keep your sleep environment consistently fresh. If you notice a mild smell when first unboxing, that's normal off-gassing and it typically dissipates within 24–48 hours. Setup is simple Unbox, unroll, and let it expand for 24–72 hours before sleeping on it. Pairs with most platform beds, box springs, and adjustable bases.

This is my first time writing a review on Amazon. I usually don’t write reviews because I don’t want to spend the time, but I felt this mattress truly deserves one. I hope this can serve as a helpful reference for anyone considering buying a mattress. I purchased this mattress on April 11, 2025, and it has been almost a full year. I intentionally waited this long to write an honest and reliable review. If you are currently doing research and comparing options, my advice is simple: you can confidently choose this one. There’s a reason it’s a best seller—it is absolutely reliable. That was my reasoning when I bought it, and after a year of use, it has proven to be completely correct. I will break my review into five parts: 1. Great value for money I believe this is the most important factor for rational buyers. I purchased the King size, and for a mattress of this size, the price is very reasonable. It is definitely affordable for the average working individual. 2. Size recommendation If two people are sleeping on the bed, I strongly recommend choosing King instead of Queen. The King size offers better support and does not feel saggy. It is more spacious and comfortable, without feeling crowded. It can even fit three average-sized women if needed, although for two people it is perfect. Of course, if your space is limited, choose what fits your room. 3. Comfort and support This was the main reason I replaced my old mattress. I used to wake up with unexplained body and bone pain, and I thought it was due to stress or aging. However, after switching to this mattress, that discomfort completely disappeared from the very next day. At first, when I sat on the edge after installation, I sank in quite a bit and felt worried that the mattress might be too soft. I even thought I made the wrong purchase. But once I actually lay down and slept on it, the experience was completely different. The support is excellent—there is no feeling of collapsing, yet it perfectly contours to the body. It far exceeded my expectations. I originally thought it was just a good value mattress, but it has actually become something that truly improved my sleep. Even if you offered me a much more expensive mattress, I would not want to switch. 4. Easy setup I’m a 5’4” woman with average strength, and although the mattress is a bit heavy, I was still able to move and set it up by myself. It’s not too difficult—just requires a bit of technique. My tip is to place the mattress onto the bed frame before removing the final plastic wrap. Then cut open the plastic, which makes it much easier to adjust the position. 5. A great wedding gift option A close friend of mine stayed over and also commented on how comfortable the mattress is. I even promised her that I would gift her this mattress when she gets married. For anyone who doesn’t know what to buy as a wedding gift, this is actually a very practical and thoughtful option. Conclusion Overall, I strongly recommend this mattress. It is one of the few purchases I’ve made that truly delivers exceptional value for the price.

I've had this mattress for about a week now. I keep reading conflicting reviews which make me think the company changed the mattress at some point. Even the title says new version so that could be why so many different experiences. I'll start off by saying I'm a 36 year old female I typically sleep on my sides or back. I usually sweat a lot. I'm about 150lbs my son is 8. Back story I just moved and my old memory foam mattress was over 10 years old and was really needing to be replaced. My Chihuahua recently died from a cancerous tumor on her foot and it was bleeding and leaking all over my old mattress. My young son and our opossum also share the bed with me and my son gets nose bleeds quite often. A gallon of milk got dumped on it at one point, peed on, moved a few times once in the rain so it had really been abused but it was still the most comfortable bed I had ever slept on even after 10 years. I even sprayed it down with bleach a few times because of what I just said and even vinegar, rubbing alcohol, peroxide, you name it and it held up great. Only problem was i had no idea what brand it was only that it was memory foam so unfortunately I had no way of ordering the same bed as my old one. This mattress: Smell So i just moved to a new area far away from where I used to live and figured I'd buy a new mattress and just put the mattress directly on the floor so I didn't have to move my whole bed etc. lots of the reviews people complain about a strong smell. I didn't notice any type of smell whatsoever even putting my face in it and taking a big whiff straight out the box. The mattress inflated immediately and although I didn't measure it, I slept on it about 4 hours after I unboxed it. It's now been a week and feels and looks exactly like it did 5 minutes after taking it out of the box. Firmness: Lots of reviews say how firm and hard the mattress is. Mine was listed as medium firmness and although I prefer a firmer mattress I went ahead and ordered it because most of the reviews say it's firmer than expected. I would say it's medium to soft. It definitely sinks in more than my old one did. I sit in bed alot with my back up against the headboard/ wall and I can tell my butt is sunken in way more than my old mattress and my butt is obviously lower than my feet when sitting up in bed. It is comfortable to sleep on but it does take a second to plump back up after I get up or change positions. Cover It says the mattress comes with a removable cover and reviews say it has a zipper. I could tell the bottom side from the top because it looks different and different material. I haven't messed with the zipper but one review said it's a fake zipper. Not sure about mine. The mattress came with the cover already on it and I haven't tried to remove it yet. My roommates son peed on it this evening and now I am wondering and hoping the cover is waterproof. By the look and feel of it I'm guessing it isn't. I will be updating my review as time goes by and say how easy it is to remove, how it holds up in the wash and how easy it is to get back on as well as what the actual mattress looks like without the cover but for now I just blotted up the pee with a clean towel and sprayed it with disinfectant and blotted again. Fingers crossed. I've also read conflicting reviews about weather or not you can flip the mattress and sleep on either side. Some say you can't some say you can. Im guessing if the cover is removed and the mattress is flipped and the cover is put back on zipper still underneath it might work but the position of the zipper wouldn't be comfortable to sleep on as it's not along the edge of the mattress but again I'll update my review when I cross that bridge. The description does show the different layers that make up the mattress so I could understand why some reviews say you can't flip it. Temperature The description says cooling and Its hard to tell because i now live in a new place further south and I have a roommate that keeps this place warmer than what I'm used to. Because of that, I now sleep with a fan although I didn't used to but so far I haven't woken up sweating yet. Size This is supposed to be a 12 in. King mattress and although I didn't measure it, my sheets do fit the same way they did before... Pretty damn tight. I think next time I buy sheets I'm gonna get the extra deep kind because it is fairly difficult to get the sheets on. I may even get a foam topper just as an extra layer of protection too since I was so hard on my old mattress and this one already got peed on and my current sheets definitely won't fit if I add a topper. That will be easier to replace when it gets yucky and I'm also ordering a waterproof cover Incase this one isn't ( I'm fairly certain it isn't or the description would have said so.) Update: It's now been almost a year the mattress is completely dipped in in the center it's the most uncomfortable soft mattress I've ever slept on I really wish I would have gotten the protection plan because I spent $400 on it and the bed sucks I'm now looking for a firm mattress this bed is horrible and it didn't even last a year I never had back pain until a couple months after sleeping on it now my back and all my joints hurt I'm very upset

We slept on this mattress at a resort cabin in Chattanooga. I called the owner to learn the brand because we liked it so much. Been sleeping on it now for several months. It feels very firm when you first lie down, but give it a chance. The memory foam slowly molds to your shape, but not so much so that it grabs you or holds you stuck in place. So, it's easy to roll over. We are both side sleepers and notice we sleep longer in one position with no pressure points on our hips or shoulders. A big benefit is is no sag in the middle because our combined weight that used to make us roll to the middle and go bump in the night even in our spendy Sleep Number matress. The Zinus is cool in the summer and warm in the winter. Setting up was simple. The new foam smell was mild and faded rapidly so we slept on it after only 24 hours of letting is expand. It's heavy, so you'll want a hard, smoot base instead of a fabric box spring if you want to slide it around. and you'll definitely want two people if you want to move it to another room. The price/quality ratio here is remarkalble.

We bought this mattress for my 5-year-old, and she sleeps comfortably on it every night. It has a nice medium-firm feel that gives good support without being too hard. The mattress expanded well after opening, and so far it has been comfortable and reliable. Overall, we are happy with it and it has been a great mattress for our child’s bed.

It's important to note that the firmness of this mattress depends HEAVILY on the temperature of your living space!! During warm summer weather, it softens up and feels more like a medium mattress. In colder temperatures, it is definitely FIRM. This was not particularly a deal breaker for me, but I know it can be for some people so I wanted to note this. I still find myself sleeping comfortably in either firmness. This mattress is pretty much exactly what you would expect from an affordable mattress. You definitely aren't getting amazing comfort from it, but its very reasonable for the price. I just needed something for my office/spare bedroom and only sleep in it occasionally. It feels supportive and conforms to your body after laying it in for a bit (but this does, in turn, make it more difficult to move around). My biggest complaint about this mattress is the packaging it comes in. The box is heavy and awkward to maneuver around even with two people. Once it's out of the box though, setup is very easy. You just unroll it and take it out of the plastic wrap, giving it at least 12 hours to expand. I bought the full size 12in mattress, and it expanded all the way within that time frame. The mattress also had no noticeable smell out of the box, which I was pleased with. Overall, this is a convenient budget mattress for a spare room/minimal usage, but I'm not sure how suitable it would be for everyday use. The differences in firmness depending on the temperature are definitely a major factor in this—it may be jarring to feel like you're sleeping in a firm bed some nights and a medium one other nights. Breaking it in may help with this or soften it over time, but I haven't tested it myself. If you're looking for a long term, daily-use mattress, I would recommend investing in something with less variability in its firmness.

I was super excited to find a mattress with no springs and no fiberglass. However, this one is not it. I have ordered from this brand before as well as Amazon basic mattress and this is the most uncomfortable one I have ever tried. I have given it chances, sleeping on it for over a week now. Every night I am waking up multiple times with back pain. I am going to order a mattress topper pad to see if that helps. If all else fails I will post it on marketplace. I should add- i am a fan of medium firm beds, pillows, etc and not looking for super soft. But having my back hurt this bad each day is not good.

I am pleasantly surprised with this mattress. It is very firm, too firm for my tastes BUT I just topped it with a memory foam topper and it's the most comfortable bed I own. I sleep GREAT and it does not stay "indented" after I get out of it.

Good quality but the mattress is VERY firm. You dont sink in at all. It aggravated my siatic and I woke up with a sore lower back. We had to get a softer mattress topper to make it comfortable.
