ZINUS 12 Inch Green Tea Cooling Gel Memory Foam Mattress, Fiberglass Free, Cooling Gel Foam, Pressure Relieving, CertiPUR-US Certified, Mattress in A Box, Queen

As a member of Vine I have reviewed a lot of mattresses and of all of the mattresses I have received for review, the Zinus mattresses are the ones that have seemed to impress us the most and stay with us the longest. My son still has the very first one we reviewed from them for his bedroom and refuses to part with it. So when it came time to buy a mattress for our master suite there was no question with what brand we would be buying. I already knew I liked the brand and could count on the quality. While I had not personally had this particular cooling mattress before I am a very hot sleeper so it was the one I decided to go with and their 12 inch mattress had served us well in the past. If you've never ordered a memory foam mattress online don't be surprised when it comes in a very heavy but smaller than might be expected box. When you open it, it looks like what I call the beef jerky of mattresses in there. Don't let the looks deceive you. The mattress will expand quickly. You want to get it into position before openining the seal. Once you do it's going to start to "inflate" at a rapid pace. We put it on the box spring (also made by Zinus) and as we had anticipated it began to expand. Within an hour I could lay on it comfortably (if it was a bit firm). By nighttime it achieves more softness and takes about 48 hours to a week to achieve full softness but you can indeed sleep on it the first night. I did not notice any odor with this mattress, and trust me I'm prone to odor induced migraines so I'd notice if there was a problem with chemical smell. I had a mattress once that I had to leave in the lanai for a week to air out. This one wasn't a problem at all. It may have a very mild odor that I didn't notice because I'm stuffy but if there is any it's really not at all noticeable enough to comment on. As far as comfort, I love this. I suffer from chronic pain. I need a mattress that bounces back to form quick so I can roll over to another spot and not sink back into the spot I was in. This does that. I would call it a medium firm. Soft enough to cushion but firm enough to give support. In my book it was money well spent. I was lucky enough to have the luxury of testing a few different brands before making a purchase but I have to say that even if this cost more than it did I still would have chosen this one. Well worth the price when mattress stores are charging five times as much if not more for comparable mattresses. If I run into problems I'll update my review as always but so far so good. Edit 1: So I've been having severe hot flashes at night for a while now. Before we got this mattress I'd wake up at least four or five times a night having a major night swear and unbearably hot. Since getting this mattress that hasn't happened to me once, so (at least for me) I can attest to the fact that the cooling effect does indeed work. I'm by no means cold but I no longer wake up feeling as though someone has suspended my body over a lava pit. What has happened however is that I now wake up with a sweaty head and am now in search of the perfect cooling pillow to go with this mattress.

Pleasantly surprised by this mattress — I ordered it after reading reviews about decent budget mattresses, and this one came up on several lists. I ordered it for my guest room, and I was very happy with the edge support, as well as the overall comfort of the mattress. It is firm (my preference) but the memory foam provides enough give to make it comfortable. If you prefer a plush mattress, this is not it, but I think a quality mattress topper would resolve the issue for most. For the price, I really can’t imagine doing much better. Bonus — very little off gassing. We opened it up and in a day or so, it was fluffed up and did not smell like chemicals. I’d definitely purchase again.

I would say its a little more on the firm side. Its also a little shy of a full 12in but my wife and I really enjoy sleeping on the mattress. It's not life changing but we don't wake up with any aches or pains. There was an odor when we first unboxed it. Its not bad but it smells like a boxed mattress. We let it inflate in the guest bedroom for ~72hrs and now you can only smell it if you smash your face into the mattress and even then its super faint. I don't feel "cold" sleeping on it but we are unfortunately subjected to a hot bedroom and I would say we don't wake up in a puddle of sweat anymore, which is nice.

I purchased this mattress (12" Queen) in early 2020. After five years, I figured I would finally provide a review. INITIAL OBSERVATIONS: You do not need to spend $4,000+ for a decent quality mattress. What matters most are the materials used in the construction of the mattress and your own preferences of size, cooling, firmness, and other features. Keep in mind this is my own experience with this mattress over five years. The mattress arrived in a box. Packaging held up well. At the time that I ordered, there was no "white glove" or similar delivery option, so my package was placed at the foot of my stairwell. I can't fault the delivery driver for not delivering to my front door since I lived on the fourth level of a walk-up and the mattress itself is quite heavy. Just be aware that if you have a similar living situation and do not see an option for in-home or in-room delivery, you may want to have one other person help you with set-up. Opening the packaging, including the plastic wrapping that protected the mattress during storing and transport, was easy but nerve-racking due to the extreme pressure of the contents. Be sure you have the packaging in the exact spot you intend to place the mattress and that no lose objects are nearby as things could go flying once opened. No insects or signs of wear and tear were noticed. The mattress appeared brand new (as expected). The mattress took about 48 hours to fully "form" and seemed slightly taller than 12". The cooling effect was not noticed compared to other mattresses that purportedly have this feature. The off-gassing (odor from newly opened mattress-in-a-box) process lasted for no more than one week and the odor wasn't terrible during this time. Be sure to air out the room the mattress is in for at least a few days if the odor bothers you. Also keep in mind that this is normal for mattresses in boxes. The mattress was very firm for at least one year with nightly use by one single male (6'0", 180 lbs). The mattress gradually softened over time. Mattress protector and bedding may have slowed the softening process. FIVE YEAR OBSERVATIONS: After five years, I can say this mattress was an excellent value. A quality mattress protector is HIGHLY recommended for any mattress and this was no exception. The outer cover that comes with the mattress is not necessarily a mattress protector and is likely not water proof or even resistant. The brand claims that no fiber glass was used as part of this mattress but many similar mattress do use fiber glass. I do not recommend taking this cover off of the mattress since dealing with loose fiber glass is a nightmare and difficult to resolve effectively. Most bedding purchased over the years fit the mattress just fine and I never had issues with fitted sheets or protectors slipping off. No excessive loss of firmness or sagging was observed with regular, nightly use. The edges are still firm and no degradation of materials was noticed. Since there are no springs, noise levels are low to non-existent. This mattress has survived at least three moves with no issues. Cleaning the mattress was not necessary for me due to always using a mattress protector. However, baking soda and a vacuum are all you need to refresh your mattress if necessary. Flipping or rotating this mattress has not been necessary for me but your experience may vary depending on use. Sleep quality has been fine. No soreness or discomfort was experienced that could be attributed to the mattress itself. If sharing this mattress, you should not feel the movements of another person depending on their size and proximity to you. I never felt like I sunk into the mattress. This mattress lived atop wooden slats on a metal frame. Firmness can change slightly depending on what the mattress sits on. It is unknown (to me) if the mattress is compatible with adjustable frames. Why Not Five Stars? Rarely does a person find the perfect mattress. There are too many variables involved. A lot goes into the manufacturing of mattresses and there are many kinds. Quality can vary greatly and many features are purely marketing. This is a solid mattress for the price and is great for when moving out on your own for the first time or for a spare bedroom. This is a perfect mattress for those who prefer firm to very firm. Many of my guests commented on the firmness of the mattress, indicating that they did not like the firmness. However, I preferred the firmness. Since there are no springs/coils, there is practically no bounce. Keep this mind for intimate times with a partner. The mattress does not seem to provide any "cooling" despite what is advertised. Therefore, you may want to avoid this mattress if you get hot while sleeping. Bedding can potentially help with this, though (cooling and breathable mattress protector, low thread count (<200) natural fiber sheets (NO POLYESTER OR SIMILAR), alpaca duvet, etc.). I regularly got too hot during sleep, even with the room cool (60-70 degrees Fahrenheit). This mattress is finally being retired into a guest room as I upgraded to a mattress made of better materials. I don't intend to get rid of the mattress anytime soon and suspect it will last at least another 5+ years with no issues. Hopefully this review helps you decide on a mattress. Mattress shopping can be very involved and stressful since there are so many options, many of which are costly. Best advice for the shopping process is to try mattresses in-person where possible.

We have this mattress in our guest room and have always gotten compliments on how comfortable it is, so when it was time to replace our old mattress in the master bedroom, we ended up buying the same one again. I am SO glad we did! Our old mattress was extremely worn out and I would sink into certain areas, so I wasn’t getting the support I needed. I had trouble falling asleep, staying asleep, and would often wake up with sore back muscles or even muscle spasms. This mattress has the perfect amount of memory foam for me. It’s not too firm, but it still provides the support I need, and it allows for enough movement without disturbing my partner in the middle of the night. Since switching to this mattress, I’ve been sleeping so much better and waking up feeling much more comfortable. I’ve only had one morning where I woke up with the same kind of soreness, and that was related to a separate health issue rather than the mattress. We absolutely love this mattress and would 100% buy it again! (Even though we did already 😉)

I’ve ordered this bed probably 6 times now. 3 times I’ve had issues with the order. Summary: if you happen to get one of the firm ones they are amazingly comfortable and a good price. As well as long lasting as my 2016 one is still good as new comfort wise. That being said there seems to be some decent quality variability issues where you might get a bed that might as well be a soft couch cushion. Worth the price when you get one of their firm ones. Not sure how to avoid this without returning and rebuying until you luck into the good ones. Quality/Order timeline: 2016: Ordered Queen 12 inch bed for myself and it said delivered but was not there. Reordered after refund and it was an amazing bed. Very firm and comfortable. And even today it holds up as my guest bedroom mattress. I’ve had multiple people comment on how good it is and my mom even got one after this after she loved it (from me). 2020: Bought 2 more 12 inch queens for my family’s house and they were great. 2021: Bought 1 for my brother who lived with me for some time and when it was delivered it was really soft. Like the softest bed your can find and the edge support was terrible. I have no idea how the original firmness could change so much but I thought it was a fluke so I returned and reordered through amazon. The replacement was firmer but still not as firm as original. We decided to keep it as he was not picky. 2023: I order my mom a king 12 inch for her birthday. It arrived great and was super firm like the original. She loves it. 2024: With my mom’s success I decide to upgrade my bedframe and get a king myself. The mattress they send me is embarrassingly soft. If I sit on the edge I sink all the way down to my bedframe laying in the center is still not comfortable but not as bad as the edge. I decide to return it to Amazon to rebuy it as I assume it’s a quality issue. They send me another and it’s the exact same thing, really soft. Sincd then I’ve had trouble sleeping, neck pains, and because the top edge sags it makes it harder to sleep right with reflux since my head is often tilted down a bit. The edge support is absolutely terrible on the new 12 inch king I got and the center is still not as firm as the original one I bought or my moms recently. I decided to return it this week. I know zinus/amazon will take my king back again and let me rebuy but it’s a pain each time to unbox, try out, and return. Not to mention they almost certainly throw away the ones I send back. So unless zinus can guarantee the firmness of another order, for the sake of avoiding waste and effort I won’t buy this mattress again. It’s a shame as the original one was my absolute favorite mattress.

This. Mattress. Is. AWESOME. This was much better than I had hoped. Like a lot of people I bought this on Prime day. It wasn't supposed to arrive until late August but came within a few days. That was a nice surprise. It was delivered in a box that was the size of an obese 4th grader and was kind of heavy but not obnoxious. The FedEx guy might disagree though. It came around 6pm in the evening and we really didn't think it would be ready for sleep by 10ish. We decided to leave our old mattress on the bed and lay this one out over it and if it wasn't ready just move it to the floor in another room. It basically comes in a shrink wrapped bag. There's a how to pamphlet on top of the roll and it's in a tarp like bag. You pull the side and the tarp bag rips open. You lay the mattress out in the shrink wrap bag then cut where you can see the two pieces meet (it's obvious). The second we started opening we could hear this thing sucking in air. It was really neat! The first 3 pictures I've included were taken one minute apart. The last one was taken around 9. By the following evening it was fully filled out. There was no smell at all, not even from the green tea. I have no idea what green tea does or does not do in a memory down mattress. Just in case, we sat out an essential oil humidifier with lavender, but it wasn't necessary. The mattress is much firmer than we expected. I personally love this since I'm a belly sleeper. My husband uses a CPAP and is supposed to sleep on his back but had not been able to do so until we got this. Seriously, we've both slept so soundly on this that I slept through my alarm for two straight hours and haven't heard his going off at 3:45am at all. He's got it set to sound like a fog horn in panic mode, I have no idea how I can suddenly sleep through the thing that's woken me up almost every day of the last ten years. What is this black magic? The oddest thing we're finding is that there is absolutely zero bounce to this. I dropped down on it today to read and it almost hurts. It must be habit to expect the bounce. Dunno. Neither of us notice the other moving. Honestly, I'm not sure we ARE moving. I've been waking up in the exact same position I feel asleep in, twice with my iPad still on my arm were it was dropped after this zonking out way faster than I usually do. We added a second mattress cover only because the I've included doesn't look like it will be easy to remove. We got the 12" version and it measures to a smidge more than that. It's also about one inch longer than our old one. I didn't realize the mattress was short, I've always thought the platform bed was made longer. Weird detail, I know. But it's nice to not have that little ledge on the bottom now. We both love this mattress and we're very different people. I'm very short, small, a light sleeper, and prefer to sleep on my stomach. He's over six feet tall, weighs at least twice as me, sleeps through actual earthquakes, uses a medical device that usually makes sleeping a little less restful, and is on his back most of the night (in theory). We also have three kids. The two older have a bad habit of jumping on beds and this nips that right in the bud. It is all but impossible to jump on this mattress. It's awesome. If you like the expensive memory foam mattresses but just can't see yourself dropping $1,000 or more for one then this is really going to make you happy. I don't have a single clue how one would go about returning this I'd they didn't like it but I also can't see someone hating it. You may not like how firm this is so if you're cool with the prospect, hit add to cart. And have a tip ready for your delivery person, they're going to earn it.

I was very impressed with this mattress from the first night. It expanded quickly after unboxing and had very little odor. The medium feel is a great balance not too soft and not too firm so it provides good support while still being comfortable. I also like the cooling memory foam. It stays comfortable throughout the night and doesn’t trap as much heat as I expected. The mattress fits my queen bed frame perfectly, and the quality feels excellent for the price. I’ve been sleeping much better since switching to this mattress. It provides good pressure relief, and I wake up feeling more rested. If you’re looking for a comfortable memory foam mattress that offers great value, I would definitely recommend this one.

I purchased this mattress in November 2025 and wanted to wait until I had used it for a while before leaving a review. After more than 9 months of regular use, I can genuinely say I’m very happy with it. The firmness is just right for us. It’s not overly soft and not too hard either. It feels firm and supportive while still being very comfortable to sleep on. My husband loves it as well, and it has continued to feel great even after months of use. So far, we’ve had a really good experience with it and I’m very pleased with the quality for the price. I would definitely purchase it again and recommend it to someone looking for a comfortable, supportive mattress without spending a fortune.

I was nervous buying a mattress online, before ever trying it out, but after reading all the reviews, I decided to take the risk. Let me tell you, it was worth the risk! Shipped right to my door by Purolator. Even came a couple days early than expected, which was a nice surprise. The mattress started to inflate immediately, no smell and up to its full 12 inches within a couple hours. The memory foam is great for my back pain. It’s a good medium-firm. I didn’t feel like I was sinking to the ground, like I normally would on a memory foam mattress. This is definitely a great option if you’re someone who suffers from back pain, or even just a side sleeper. Also great if you sleep with a restless partner like me, my boyfriend got a good night sleep without the bed moving or bouncing around anytime I turned. I would compare this to an Endy, but better, and half the price.

J’ai pris le temps de bien magasiner et regarder les différentes options pour changer mon ancien matelas qui me donnait de grosses douleurs dans le dos. Celui-ci a attiré mon attention avec son prix très alléchant et le nombre élevé de commentaires positifs à son égard. Malheureusement, je ne peux aller en ce sens…Mes douleurs au dos sont encore plus intenses dû à son extrême fermeté et malgré la politique de retour qui semblait simple avant de l’acheter, ce n’est pas du tout le cas et le retourner était très compliqué! J’ai donc abdiqué et l’a gardé…Je crois donc qu’il est important pour les futurs acheteurs qu’ils soient au courant de cela et soient en connaissance de cause..

Replaced the mattress that came in our trailer with this one and it’s been a massive upgrade—way more comfortable and supportive, no more waking up with a sore back like the flimsy stock mattress used to cause. The cooling gel memory foam actually helps too, not waking up overheated in the middle of the night like before. Setup was easy, expands and airs out quickly once unboxed with barely any smell. Feels like a real quality mattress despite coming compressed in a box, holds its shape well and doesn’t sag in the middle. Great affordable way to make trailer sleeping way more comfortable, would definitely recommend if you’re stuck with a cheap factory mattress.

I chose this mattress because I am strictly a side sleeper and have a sensitive knee. So far, it is very comfortable, but I would recommend trying a memory foam mattress in person to see if it is right for you. Memory foam mattresses feel significantly different from regular spring/hybrid mattresses. The mattress will take at least 72 hours to fully decompress. Even after 3 days, mine is still softening and expanding. The mattress will feel rather stiff on the first night, though it will soften up as it expands. Mine did not have a noticeable smell, but this will likely vary between mattresses. Overall, I think this is a great mattress and the value is very competitive to IKEA and other mattress retailers. It may not be for everyone, so I recommend that you test some memory foam mattresses before purchasing.
