The mattress ended up being about what we had expected. More firm than a traditional spring mattress, but softer than others we have either slept on or tested out in a store. We, like most, were tempted in spending much more money from either a store or a bigger name brand online, but overall are very satisfied with our purchase. We also purchased the normal Zinus frame, which went together easily and has been doing a good job for us so far. Packaging. It was easier than expected and the box wasn't as heavy as I thought it would be. It was easy enough to open, get the mattress out (that was nicely packed) and into our bedroom for opening. At some point during the process, we must have torn a small hole in the plastic bag and we could hear air starting to get in. Thankfully, we were able to get the mattress on the frame and the plastic off before too much expansion happened. Set up/Expansion. We slept on the mattress the first night we set it up after about 6-7 hours of expansion. We felt like it was around 11", so we wanted to try it out. After sleeping on it over this past week, it has grown to 12" all the way around. We slid some cardboard (from the shipping box) under the mattress and on the frame to prevent the foam from leaking through the slots. It's worked great so far! Smell. I hesitate to actually say this, but my wife swore for the first couple of days it smelled like Peanut M&M's. She has a weird sense of smell, but it did have a smell, although not bad or overpowering at all. After a week we don't notice anything at all. Firmness. We decided with this mattress in particular because it was supposed to be softer than others. We're glad we got this one, because it is still more firm than we are used to. After a few adjustments to how we sleep, we both find the bed very comfortable and it is great. Movement/Support. Although we haven't tried the wine glass test shown on older commercials, we have tested seeing if we can tell if the other is getting in or out of bed. For the most part, we can't tell. Like almost all foam mattresses, if you are too close to the sides, you will find there isn't a lot of support. I sleep pretty close to the sides and haven't had any issues. Overall impression. I am VERY satisfied with our purchase. Not only did we save HUNDREDS (if not thousands) of dollars, it was delivered quickly and easily. We haven't had to deal with customer support, but hopefully between Amazon and Zinus we could resolve any issues if they were to come up.

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.

If you're looking at this, just buy it. Do it. A king size memory foam mattress for $360.00?? It's an absolute steal at that price and the quality is excellent. I, like most people, was extremely sceptical about buying a mattress online, sight unseen, but I'm so happy I did. My girlfriend and I have been sharing a full size bed for over two years and this was a purchase that was WAY overdue. The only thing that stopped us was the hefty price tag from the regular stores. I'm a slim guy @ 6'2" and she's a short little lady at 5'3" but the full bed was just too small for the both of us to sleep comfortably. The first night we slept on this bed I woke up twice because I couldn't feel her next to me and instinctively was worried that she couldn't sleep and was on the couch. Finally I can sprawl out all I want and there's still plenty of room! I gave the bed almost 72 hours to "inflate", or whatever you want to call it. After the 72 hours or was at its 12" height and all the corners were even and the bed was just great. It is a little more firm than our old bed but I suspect we just need to break it in over time by sleeping on it more. But it's still VERY comfortable and I'd buy it again in a heartbeat if something ever happened to this one. Besides, there's something to be said for a memory foam mattress after sleeping on springs your entire life. I can't say enough good things about this mattress. If you're on the fence or worried about the price tag, I'd say, just buy it. You won't regret it! Edit: I honestly can't believe all of the negative reviews on this mattress. For those worried about the smell, It did have a small to it when it came out of the bag, but after letting it sit for 72 hours to decompress the smell was gone. The bed is still on the firmer side but still so comfortable. The firmness is SUPPORTIVE. My ONLY complaint is that the bed is very warm, I counteract this by using a thinner blanket and sleeping with the windows open (per usual). Still 5 stars, and I'd still buy it again.

I've been sleeping well lately on my Zinus 12" mattress. Both my wife and I like it a great deal. First off, we like a nice firm support, and this is definitely a firm mattress. No matter what they say about the plush feel of the memory foam, this is a mattress that -- at its core -- is darn firm. That's good for us. May not be good for someone expecting to "sink into" the soft top layers of memory foam. Won't happen. My comments are the result of my purchase, on Amazon, of a defective one that had to be disposed of, and finally a replacement that works beautifully. I would suggest that the comments from the manufacturer are very iffy as to "truth content." Yes, it's a good mattress, and we're comparing it to a Spring Air brand (spring type and box springs) that we had for 20 years previous, and that Spring Air cost a number of magnitudes more than the Zinus. My issues are the BS they load the sales information with . . . such as, expands in 48 hours (takes a couple of weeks in our experience to fully expand), or the "smell goes away in 72 hours" or something like that. We're still experiencing that chemical foam smell, a couple of weeks into it. I sure don't smell any essence of green tea or whatever that was supposed to be all about! This is just one stinky piece of foam -- but we kind of expected that, so it's not a disappointment. But I do believe that the photo their marketing people use (of a perfectly squared off corner, and a perfectly expanded foam mattress) are a bit over the top, and that has led to some of the griping you find in the lower star reviews. I've had two now, and neither one expanded properly in the corners. Nor was either one 12" high . . . They are about 10.5" high when they appear to be fully expanded. The defective one we had was 9" in some areas, and 11" in others, so that's not acceptable. But the replacement we have is perfectly inflated, and the same height (10.5") all around. The corners don't look like the corners in the photo that is used here, though. And I don't think that matters personally. The ultimate goal of a new mattress is to give you an improved sleep. For my wife and I, this one delivers on that promise and represents a good value. I would suggest, however, that they start marketing it realistically and they will avoid people complaining about each and every little thing. There's one negative review here with photos and believe me, I'm sure thats still a darn comfortable bed to sleep in, and that the corners being slightly goofy looking has nothing to do with the sleep performance of the bed. I've downgraded the review from 5 stars to 4 stars because of this tendency the company has to make all kinds of statements that just aren't true. Are they selling a good mattress with a great value? YES. Are they selling a non-stinky mattress that's cool sleeping and that has a wonderful green tea gel and that perfectly expands when you take it out of the box? ABSOLUTELY NOT. It's up to you what you decide, but you certainly are going to get your money's worth here, as long as you enjoy a firm mattress. It has a pleasant soft and cushy feel when you lay down, coupled with the feeling of firmness that you need if you have back issues. My only disappointment is their marketing description and the tendency to go with significantly overblown statements.

i’m one of those people when i make big purchases, i always read a ton of reviews. when i looked at the reviews on this mattress, i saw a lot of people say it was extremely soft and they love it so much, while others have said it was super hard and uncomfortable. i think ultimately it depends on how much you weigh. i’m 115 pounds, so when i lay on the mattress, i don’t sink into it so for me it’s a firm mattress. i just kind of lay on top of it. my husband on the other hand, sinks into it and for him it’s very soft and comfortable. i don’t wake up with any pain, but it’s definitely very firm for me. the cooling part? yeah i’m not so sure about that. i’m a super hot sleeper so that’s why we opted for it, but i don’t know that it’s really made a difference. i don’t wake up sweating, but i don’t feel it “cooling” either. possibly the best part though is the fact that if my husband moves around, i don’t feel it at all! when our dog jumps on our bed, it usually wakes me up, but with this mattress i don’t feel it whatsoever! overall it’s a great mattress for the price point. if you’re pretty lightweight and want a super soft mattress, this isn’t the one for you. we’ll see how it holds up over time. i know some people complained about the smell after unboxing, but we had no issues with that UPDATE AFTER 10 MONTHS: we still love this mattress!! it’s fantastic! it hasn’t developed any craters or anything and has held up really well over time. it’s still incredibly comfortable and we love it!

Let me begin by stating that we bought the Zinus 12” memory Foam Green Tea mattress for our daughter in 2017 and it is the most amazing mattress! 6 years later I am Still unbelievably enamored with the quality and comfort of this mattress. When it was time to replace my mattress, it was a no brainer. Then I saw the same mattress with the cooling gel and thought “we’ll I don’t want to be hot” and hit order. Biggest mistake of my life and I have made my share of bad decisions. First the pros: It came on time. It puffed up to full height very quickly and stayed there! Now the cons: Within a week, divots appeared on each side that did not go away. So now I sleep in my hole or claw my way out to try to reach the middle of the bed. This bed is so hard that nightly I wake up because my arms have fallen asleep. Yes, it is rock hard AND has permanent divots! I tried to work with customer service and measured the divots but because they were only 1”, they pretty much told me to pound sand. 1” may not sound like a lot but when you are trying to roll across your bed, it feels like a lot! If I had not purchased the best mattress in the world from Zinus, I would chalk it up as a cheap crappy mattress from a cheap crappy manufacturer because the Zinus mattress’s are incredibly economical compared to the box store mattress’s. Sadly, having an amazing mattress from this company just makes the disaster of this mattress hurt (figuratively and actually) even more. Still interested, I don’t blame you, they are pretty cheap, just make certain your chiropractor is on speed dial.

As a college student with his very first own apartment I wanted to purchase my own mattress with something that I liked. In the past I was not able to get a memory foam mattress all other previous mattresses I had did the job but it wasn't truly a 100 percent great night sleep. Now I did a lot of research on what mattress would work best for me. I sleep hot and also am a side and back sleeper and when I saw the price for the zinus cooling gel memory foam mattress in a king size I couldn't believe it so I took a chance and decided to order. It just arrived a couple days ago and I can honestly say you won't regret it. The memory foam is so comfortable and plush especially with the gel top that makes it nice and cool which is perfect for me. I even had enough money left over to buy the zinus bed frame as well and will most definitely be purchasing a zinus headboard to go along with it. This mattress provided me with the best sleep I've had in a while after following the instructions and letting the mattress decompress and air out I decided to test it out and within 10 minutes I fell asleep to my surprise (also was late to class but it was worth it). Now all these reviews commenting on the smell and how it didn't decompress to the proper height most likely were not following the instructions. First off let the mattress decompress a full 48 hours to let it rise to the proper height and make sure it has plenty of space to unwind. Second let it air out due to the green tea it will have a faint scent but after letting it air out it was not an issue. Third I bought the zinus elevated bed frame because if you own a memory foam mattress you are supposed to elevate the mattress and make sure the bed frame has openings to allow air to circuit and not let moisture build up such as letting it sit on the floor or wood. So for around $340 you can get yourself a quality mattress delivered to your home without breaking the bank. As a side note I was not paid for this review or discounted in any way I just provided my honest opinion for the mattress so others can benefit from honest non-picky reviews.

This review is going to be pretty long lol because I feel like buying a mattress is a big purchase. You know you're paying money for something that you can't physically feel or test out. So i want to try and help others that are interested in buying this bed be well informed. I purchased on March 9th and it arrived March 11th. When it arrived UPS left it on my back porch. It was a big box, and it was heavy. I probably couldn't have brought it in by myself. But my husband was able to carry it in. We opened the box and I read the instructions and you could just tell from the instructions that it was awesome quality. It came with a little pamphlet and they had thank you cards that you could pass out on special occasions. (I don't know why, but i thought it was neat they did that) We pulled it out of the box, unrolled the mattress then we took the plastic off and I noticed like a hump in the middle from it being rolled up. But when the mattress started forming it went away a little bit. I can still feel the hump a little bit but I've only been sleeping on the mattress for a little over a week so I'm sure it will disappear. When we took plastic off and laid it out, it started rising already. We opened it about 1 pm and by the time bedtime came around it was already fully developed. But we waited to lay on it like they recommend, just to make sure it formed to it's full potential. I think the bed is a little firm but I think we just have to "break it in". I'm still giving it 5 stars because the instructions were so easy and simple, the bed is really nice quality, I feel this bed will last me years, and the shipping and packaging was good. So i don't want my personal opinion on the firmness of the bed to take away from the seller or the product. I read the reviews before buying and I seen people talked about a "smell" but mine didn't have a smell also it said it was infused with green tea but it doesn't have a green tea smell? My advise is to BUY THIS BED. But if you prefer a softer bed, I would order maybe the 10 inch? But if you like a firmer bed the 12 inch is the one you want.
