Great mattress at a low price
Great mattress so far came out of the box easy enough and decompressed faster than I thought it would. No off gassing, quiet and comfortable. Feels heavy, solid, and firm but not too firm. Great mattress for the price

Amazing
I bought this one year ago, in February. I opened it up to use it a month or two later when I moved into my new apartment. Let me just say: amazing. This was my first time buying a mattress for myself and I was so worried I’d pick the wrong one. I did lots of research and I found this one and I’m not going back! I will say, order it closer to when you need it, I kept it in the box for a month or two and then I opened it, there were instructions to open it with a few days (oops). But it did just fine and expanded to its full size with no issues. It was extremely easy to set up. If I remember right, you can sleep on it a few hours after you open it and it will still be expanding. It didn’t take a long long time to inflate. Sheets fit just fine on it, I’ve had no issues with that. It’s very very comfortable. Amazing for the price, I will be buying another for my guest room. I took these photos when I first set it up, almost a year ago. There’s no wear or tear now. I’m still very happy with my purchase. When my husband (then boyfriend) moved in with me, he’s had no complaints. We do not roll in the middle and stay put where we are so I really like that. It’s easy to get out in and out of. I really like the memory foam, it’s very comfortable but doesn’t feel like I’m sinking.

Updated I hate this mattress so much
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

Great Mattress
Great purchase for my daughter’s trundle bed. Super plush and comfortable, doesn’t even feel like it’s only 6”. No odor detected when opened. Took a good 24-36 hours to reach its full size, but could be used right away. Super happy with purchase!

Hard as a rock
This bed is comfortable but beware- its hard as a rock when on a proper boxspring. I really suffered with headache/neck issues for 2 weeks after sleeping on it due to a terrible flat pillow combined with this mattress. I then bought a specialty support pillow, mattress pads (2) and I was fine. So just please be aware, this is a VERY firm mattress. It might not work with your old pillows, so make sure you have a pillow/padding that is adequate so you do not suffer like I did. Otherwise, the mattress is very well made and a quality bed. It was much firmer than I anticipated.

Can’t beat the price
Excellent quality for the price. Feels extremely firm at first but really forms to your body. Easily as nice as our much more expensive casper. No smell, at all. Came to life after a couple of hours after being unpackaged. Very heavy, but fits a perfect queen bed. Very much worth the price and then some.

Excellent Comfort and Great Value
I am very happy with this mattress! It expanded quickly after opening and had very little odor. The memory foam is soft but still supportive, providing great comfort for my back and helping me sleep better through the night. It feels high quality for the price and offers amazing value. I would definitely recommend it to anyone looking for a comfortable and affordable mattress.

I’m NEVER going back to a traditional Mattress and this is why. I’m a mother of 5 going on 6 kids. We have a strict budget. I’ve struggled to find a good mattress that’s affordable for literally years!! I’ve tried all sorts of toppers that cost me an arm and a leg. I’ve spent good money on expensive traditional mattress’s. Until last year, I broke my back in a horse riding accident, in 4 different places, I’ve been having a hard time sleeping ever since. My back is never happy, doesn’t matter what I sleep on I always wake up in pain. I spent the night at my sister’s one night, and I couldn’t get over how comfortable her mattress was. She said it was just a cheap mattress from Amazon. I was like what! So I started looking into the “bed in a box” and I bought this one. And when I tell you that this mattress is the BEST mattress, I mean it! It’s soft but firm, it shapes to your body, you feel supported yet comfortable, I slept like a BABY last night! And I didn’t even have to wait for it to inflate, it just puffed up as soon as I opened the package. Quality is everything to me, and this is GOOD quality. I got the 12 inch king, only because I’ve never tried these beds before, and since they are basically foam and air I wanted the maximum thickness to prevent it from flattening. But this mattress is STRONG, it feels like a magic trick, and I loved the experience of unboxing. We threw it on a platform bed frame I bought, and BAM! My life is changed forever. I bought 3 twin sizes for my kids too of a different brand. Those ones are great too, but took longer to inflate. This one was even better. We ALL love our beds in a box. I can’t wrap my head around all the wasted money on traditional mattress’s and fancy toppers over the years. Not only that! It was so convenient to haul in my car, just a box. Not this awkward big mattress that needed a truck, no you can fit this box in the trunk of your car. Which is also very convenient, because I live a ways out of town and I get my Amazon packages delivered to a friends house. So when I brought this home it was soooo convenient. I’m so thankful and blessed that I get to have good sleeps now. Which is literally everything when you’re a mom like me, with a back injury. I can’t shut up about it, I feel like I have hope for good rest, and that means everything to me! It’s horrible living with chronic pain and constant fatigue from terrible sleeps. I could cry I’m so happy. Please if your like me! Consider it. It’s worth every penny. And I don’t get anything out of writing this review other than just hoping that someone else can find relief too! Sleep is so important. Thanks for listening to my Ted talk! lol

This mattress is advertised as medium-firm. I purchased the 12" version as I have previously purchased the 6" version and loved the firmness. everyone who has slept on the 6" mattress says it's the best sleep theyve ever had. The 12" version has come up short. It's so soft. when you sit on it it sinks quite significantly. the impression from my body stays in the bed for a while after I get up. I am so disappointed in this bed especially considering my previous experience with Zinus was so fantastic. I did not find the smell bad, but I also just had new carpet installed so my house smells like new carpet. I would describe the firmness of this bed as "extra soft" not medium firm.

The Zinus Green Tea Infused Memory Foam Mattress is comfortable right out of the box. It feels supportive and helps with pressure relief for side and back sleepers. There is very little odor after opening, and the mattress expands quickly to its full size. The edges are a bit softer than the middle, which may matter if you sit on the side of the bed often. For the price, it’s a really solid choice for guest rooms or everyday use. Pros: Soft and comfortable feel Expands quickly after unpacking Low odor Cons: Edges are softer than the center May sleep slightly warm for some people Overall, this mattress is reliable and very comfortable for the price.
