I’ve been sleeping on this ZINUS Green Tea Memory Foam Mattress for a few weeks now, and I’m very happy with my purchase. It expanded quickly after unboxing and had very little odor. The mattress feels medium-firm, which gives me the perfect balance of comfort and support. I wake up with less pressure on my back and hips, and I sleep much more comfortably throughout the night. The memory foam adapts nicely to my body without feeling too soft or sinking too much. I also appreciate that it’s fiberglass-free, which gave me extra peace of mind. For the quality and price, this mattress exceeded my expectations. I would definitely recommend it to anyone looking for a comfortable and supportive mattress without spending a Fortune

EDIT: 3 month update.....I'm still leaving it at 5 stars. We have now had this mattress for just over 3 months and still love it. I am falling asleep faster, staying asleep and waking up feeling more rested. I have slept on both sides and even in the middle of the mattress and have equal comfort anywhere. I normally have 3 dogs hogging the bed and what's really nice is I barely notice if they get up and move to a new spot, even if it's right next to me. I no longer feel like my husband is doing backflips if he turns over in the middle of the night either. Even the one night the mattress pad didn't make it into the dryer in time for bed I did notice the difference the mattress pad makes in not making this mattress feel as firm, but it was still quite comfortable, just not as comfortable. I have no complaints. There were no smells with ours to start with so that never was a problem and it's still at a full 12" evenly across. I'm in the camp of those who were really skeptical of buying a mattress online. Especially a foam one since I've had a regular pillow top one for the past 10 years. Yes it was time for a new mattress! I had been shopping around for a new mattress for a few months trying out different ones, getting pricing and trying to make a decision which is kind of a big deal when you're more than likely looking at spending a lot of money. A friend suggested we consider the foam mattresses and that Amazon had some good prices on them. I headed to a local store to give their version of these mattresses a try and I was surprised how comfortable they were. After testing them out I decided to see what Amazon reviews had to say about the ones they offered. I read through the good and the not so good and the flat out bad reviews and decided to take a chance and see what arrived. I am super happy I did! Granted it's only been 2 weeks but so far we love this mattress! I had read the multiple reviews saying theirs didn't inflate correctly, had a foul odor, was lumpy, etc....thankfully none of that was true of what we received. To break it down..... cons... It is a firm mattress no doubt. I am someone who likes to pretty much sleep in a cloud and am a side sleeper so it's taken some getting used to. Since the cost of this mattress was so good I went ahead and ordered a high quality mattress cover/pad and for me it's really helped make adjusting going from a plush pillow top to a firm bed a lot easier. Going from a spring mattress to a foam ones takes some adjustment on the support on the sides. Obviously the spring ones tend to have more of a frame around the edges so sitting on the side of the bed is different. I wouldn't say it's bad but it's not as supportive. We will probably need to get a new bed frame here sometime soon. While the box springs we had from our old king are still in great shape the lighter weight mattress tends to slide and needs to be shoved back into place every night before going to bed. Not really any fault of the mattress it's just a con that I'll need to replace the bed itself in order to stop this from happening. Another con that's not the fault of the mattress it's just my bad luck....I missed where this was on sale just after Thanksgiving because I was still pondering what kind of mattress to get. So I paid the higher, yet still on sale, price. 4 days later it went back on sale again and has remained $40 cheaper for over a week now. Bummer for me, but still a good deal, just not as good of a deal as if I'd waited 4 more days to decide. On to the good stuff Pros..... Per my experience I say buy this mattress. Don't wait, grab it at the price it is now. I did not notice any sort of foul odor but I did open the windows and had the ceiling fan going while it inflated. It inflated to the full 12" and did so within an hour. We were sleeping on the mattress withing 4 hours of setting it up. It fit where our old king size was perfectly with no overhang or shortages size wise. It's around 2" taller than our old mattress so that took a little getting used to but it measured 12" with a regular school ruler. It was well packaged and fully deflated ready to go when it arrived. I'm a big girl and my husband is a fairly big guy and we both sleep comfortably on this mattress with our 3 large breed bed hogging dogs. When my husband moves at night he does so like a fish out of water and I have noticed he doesn't wake me up turning over because it's not bouncing me around like our old mattress did. I don't even really notice a dog moving around to a different spot. I'm a side sleeper who would love to sleep in a cloud so this did take some getting used to but it's never been uncomfortable. The first night getting to sleep and finding a comfortable position took a little bit but I could instantly feel I was better supported and my hip and shoulder didn't have the pressure it normally would. When I turned onto my back I felt almost like I was sleeping in a hammock. Not totally of course but the extra support was there where it hadn't been before. With what I saved on the mattress I went ahead and bought a nice mattress pad/cover to put on top to make it a little more soft. I had always been told you can make a firm mattress more soft but you can't make a soft mattress more firm so if it's too firm invest in a good pad and it can make a lot of difference if you prefer a softer bed. What I noticed right away is when I woke up I wasn't as sore. I feel a lot more rested in the morning and I'm not waking up to turn over or move around near as much as I was. Granted our old mattress was 10 years old and that had a lot to do with it, but still this mattress is obviously better and keeps me in a deep sleep for longer periods throughout the night. My husband also says he's sleeping better and isn't flopping around like he had been doing with the old mattress. He's the one of us always complaining about being hot while sleeping and he said he hasn't noticed this mattress makes that any worse, and if anything since he's not moving around so much it's better. We like it so much we plan to order the 8" version for our kid's bunk bed here soon. As we get more use of out this I will try to update this review for how it's holding up. I don't expect to get 10 years out of it, granted i probably shouldn't have tried to get 10 years out of the older one but it held up for at least 8-9 of those years. For this price I'd be happy if it lasts a couple of years. If it lasts longer even better. I highly suggest if this is too firm for you to buy a nice mattress pad and to buy it while it's at the price it is now.

HERE IS ONE OF THE MOST IN DETAIL BRUTALLY HONEST REVIEWS YOU WILL READ. I'm a 16 y/o girl who bought this mattress for my room makeover. The price is totally unbeatable and I thought well, I'll just go for it. Here's my full breakdown and opinion on anything you could worry about for a mattress: THE COMFORT LEVEL: 10/10 I may be 16 years old, but I have bad scoliosis that affects my whole body. So I still get knee pain, all that fun stuff. Before I had opened the box and set up this mattress, I had also gotten into a bad car accident that hurt my lower back even more to the point I couldn't walk. At this point in my life, comfort is my holy grail. As a growing teenager, I needed to count on something that I could also sleep on for 12 hours and wake up feeling like I could take on the world! And this my friends, THIS is it! The comfort is amazing. My back doesn't hurt at all when sleeping on it to this day, even compared to my previous expensive serta mattress. I know a lot of people worry about it sinking over time. I weigh 105lbs but there are absolutely no signs of sinking no matter how long I lay on this bed. Also, it isn't super squishy. The perfect amount of plush with a hint of firm so you aren't sinking to the pits of memory foam. THE SIZE: 10/10 When I cracked this baby open, it immediately popped up. I didn't even wait the full 24 hours before laying on it because it immediately grew to it size! I even measured the corners! HECK YEA! CLEANING IT: 9/10 Don't know what the fake zipper is about on this mattress, but this baby is so easy to clean. MY SISTER POURED CRANBERRY JUICE ALL OVER MY MATTRESS! And as I was cursing her out and shaking my fists to the heavens asking "Why me!", sad that my brand new mattress could potentially be soiled forever, it was all okay after I grabbed some odoban!! I cleaned that sucker to the gods and now there is not a single stain!! Make sure you dab people and HARD! You can even rub it, it'll come out. And then I did what a smart human would do, put a mattress cover on. THINGS THAT BOTHERED ME: 1. I don't know if it is just me but....PREPARE FOR THE SMELL! It doesn't smell like green tea nooooo definitely not sis. This smells exotic. Not my favorite smell it was definitely a strange smell that I can't even identify. BUT THAT SMELT WEIRD! And I'll be honest...it took 3 weeks for me to not smell it. It was such a strong smell that I just made my bed and didn't sleep on it for a while. It made my sheets smell too at one point. Then I got used to the smell and just decided to kick it in my bed because I was tired of sleeping on the couch as soon as the smell died down. But by the next month, I no longer smelt it. I'll list below how I managed to get rid of the smell. BUT! If you are patient like me and are willing to pull through because it is a TOTAL pain in the butt to send a mattress back, then don't fret! It does go away and you will love the mattress after! Its been 3 months that I've had it and I've had multiple people do a smell test, the smell has vanished. I still think the mattress is worth it! HOW TO REMOVE THE SMELL: -Don't use too much febreeze. It'll be a temporary assistant, but honey it isn't worth it to drench the bed in more chemicals making the bed come up with more of a foreign smell. -I put scent soaking rocks in my room. You can buy these at home depot, they take away any weird scents. You can also purchase a air cleansing machine, NOT a dehumidifier. I don't know exactly what these things are called but my boss has one and they work great. You can get these for cheap at walmart. -Air fresheners for the car. A canned air freshener will definitely get rid of the smell but they are very strong. I just got some plain smelling glade air fresheners and put them under my mattress. This made my mattress smell like fresh linen by the second day. -Wait that sucker out! It's not too bad! 2. The heat, at first My mom just looooooooves to keep our house at 69 degrees making me a living ice cube. Therefore, I keep my vents closed. But, this bed will get you pretty hot sometimes. It could just be because of my comforter, but I never sweat and sometimes I will wake up sweating on this bed. This isn't an extremely justifiable complaint because it could be any other factor, but rest assured my vents are open fully because I do not want to smell like sweat! OVERALL.....This is a definite cop, not drop! Go ahead and buy this bed. If you are extremely picky, this bed is great to have in a guest room or maybe if you own airbnb's. They're cheap and comfortable and great as long as it air's out. I love my bed so much to a point that I don't wake up for days now!

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.

We’ve purchased the Zinus Green Tea Memory Foam Mattress twice over the past year—one for my father-in-law and one for ourselves—and overall, we’ve had a very positive experience. The mattress arrived well-packaged and expanded quickly once opened. It has a comfortable, medium feel that provides good support while still contouring to the body. Both my father-in-law and we found it helped improve sleep quality, especially in terms of pressure relief for the back and shoulders. One thing I appreciate is that it doesn’t feel too firm or too soft—it’s a nice balance that works well for different sleeping positions. The foam also helps reduce motion transfer, so it’s great for undisturbed sleep. It is a reliable and affordable mattress option that has worked well for both older and younger family members in our home.

Update: Mold, serious caving in, and remarkably bad customer service has left me no choice but to downgrade this to a 1 star review. I have purchased several of these and almost every one of them has had a problem sooner or later. It looks like mold is an inevitability with this mattress. And that’s some nasty stuff to breath in 8 hours a day. I'm going to do everyone who reads this a massive favor. I'm going to tell you how I got the best bed ever, and it starts with this mattress. Let me start off saying that I have spent an unusual amount of time mattress shopping. I gave up on stores a while ago, and have been testing out the latex/foam options for a few years. The price, durability, and ease of shopping is hard to beat. I've tried all the major options; Purple, Tuft and Needle, Dreamforce, Tempurpedic, etc... The first Zinus mattress I got was all screwed up (images attached). But Amazon replaced it quickly. The most common complaint on this mattress is it's too firm, and I can see what they're saying. I'm a big (fat, over 300) guy, so I like firm. But most the people who have been in the bed are not so big. So, I decided to take advantage of the fact this was so cheap and went ahead and added two other items. First, DreamFoam Bedding DF20GT2066 2" Gel Swirl Memory Foam Topper, King, Aqua Blue This gel topper is great at keeping things cool, and has a good amount of give to it. Second, Cheer Collection Ultra Plush Eco-friendly Hypoallergenic Bamboo Fitted Mattress Topper - King this pillow top topper adds yes another level of cushion, and yet seems to let the cooling factor of the get topper come through a bit. Between these added items, I think I have created quite possible the best mattress I've ever experience, far better than Purple, Tuft and Needle, Tempurpedic, etc..., and all for well under $400! It's comfy, firm, and doesn't get too warm. I have a couple suggestions that I think really help. First, make sure this sets on a completely flat surface. If you get a platform frame with a mesh bottom, add a sheet of plywood under the mattress. I do feel this makes a bit of difference. Second, use a mattress cover on the Zinus. This thing should last forever if you don't damage it, so protect it. With the other two covers you'll never actually be touching the mattress. Just replace the toppers every couple years. A bonus suggestion, especially since this whole set up is so cheap, is to treat yourself to some bamboo sheets. HotelSheetsDirect 100% Bamboo Bed Sheet Set (King, Dark Gray) These feel amazing, and they're only $50. For pillows I'd recommend getting some traditional pillows, as well as some latex filled. The combo is a nice addition. I really stand by this suggestion, so I hope someone finds it helpful. Let me know. One year update: Matress and pads still fantastic. I rotate it once a month, just as a routine. Still perfect.

THIS 👏🏻 BED 👏🏻 IS 👏🏻 THE 👏🏻 JAM. First off, I'm a flight attendant. I sleep in a lot of hotel beds. I know what a good and bad bad feels like. THIS BED IS AMAZING. Feeling impartial about the non conforming bed of the future? Think you'll miss the springs? No way. I promise. I felt the same. I sat there for 36 hours straight watching this bed rise in my kitchen festering the idea that I made a mistake. What is this? Why does it have to rise? Who even am I right now? The instructions were like one sentence and I probably messed it up. Omg what if I messed up?! 2017 is weird, I hate this. I hate New things. JK NOPE. I HAVE NO REGRETS! This bed cured my boyfriend's back pain. This bed cured my sleepless nights. MY PHAT @zz can sleep on my side without my spine feeling broken in half. I can sleep on my back or stomach no problem. I can't remember the last time I slept through the night... Now I can't wake up. We spent three days sleeping til 2pm. Today I missed my alarm for work by 2 hours. I legitimately slept through 2 hours of backup alarms that go off every 10 minutes. THIS BED IS THE DEVIL. But like a good devil that greets you with puppies and all things great in this world. This bed is the Oprah of beds. This bed is like getting a whole row to yourself on an airplane. This bed is like seeing your ex and they look like a potato and your eyeliner is so fleek it pierces their heart. This bed is freshly signed divorced papers. THIS BED IS ALL YOU NEED IN THIS LIFE. Its dirt cheap, soft yet firm, and will make you laugh pretty hard the first time you're trying to get rowdy on it. I've had this bed a few weeks now and I am pretty convinced that this is the best decision I've ever made in my life besides losing my virginity and buying a motorcycle. TOP THREE for sure. So stop debating and order this bed. Just do it. (Shia lebeouff voice) (I probably spelt that wrong) Oh and it doesn't smell bad. I read that it did. It smelled like it was compressed in a bag and shipped across the country which was expected, but it went away. Also the box makes a rad cat house. Xoxo

I purchased this mattress for a smaller space and have been very impressed with the overall quality. It expanded properly after unboxing and reached its full size without any issues. The memory foam is comfortable and provides good support while still feeling soft enough for a restful night’s sleep. I also appreciate that it sleeps cooler than I expected, which helps prevent overheating during the night. The lightweight design makes it easy to move and reposition, making it a great option if portability is important. After extended use, it has held its shape well and appears to be very durable. For the price, this mattress offers an excellent combination of quality, cooling, fit, portability, expandability, and durability.
