    • MMMMmmm Bed... Comfort, ease, and great priced
Color: White Size: Queen Style: 10" Pattern Name: Cooling (New Box)
This mattress is amazing and the cooling gel, medium firmness is so comfortable. I’ve used this brand before and have never been disappointed. Every time I’ve recommended it to friends or family, they’ve loved them too It’s super relaxing and supportive, and I’m getting good restful sleep again after sleeping on my couch from Nov ng and accidently destroying my 7 year old previous Zinus. The price for the quality is outstanding and makes it even better. If you’re looking for a mattress that delivers comfort, reliability, and value, I highly recommend this one. However, if you do prefer a more soft one, this one does say medium firm, but I think it is a little closer too firm and there isn't a whole lot of sinking in it, but there never was in my previous one either even after 7 years, and at that age that truly shows it's durability level. I also have dogs that sleep with me and act rambunctious on it. I would say for the price, the ease of setup and the tiny box they send it in, the comfort level, and the durability level I don't think you can do better and I have even slept on those $10,000 mattresses. ... show more

    • Great Quality
Color: White Size: Twin Style: 8" Pattern Name: Cooling (New Box)
This Zinus 8” Twin Cooling Memory Foam Mattress was a great purchase for my little daughter. It’s soft but still supportive, sleeps cool, and has no fiberglass, which gives me peace of mind. She’s been sleeping comfortably every night, and delivery was fast and easy. Great quality for the price!

    • Firmer than expected, great value with a warranty!
Color: White Size: Twin Style: 8" Pattern Name: Cooling (New Box)
This is our first bed-in-a-box purchase, so we weren't sure what to expect. The bed came in squished in a bag. Once opened, the mattress expanded in about 24 hrs with no noticeable odor (which is impressive as my wife is pregnant and has a hyper sense of smell). The bed is much more firm than we were expecting. It's not uncomfortable, however very firm, despite it being listed as "medium". It's being used as a toddler bed, and he doesn't seem to mind. I would not recommend it for side sleepers, however it's fine for back/stomach sleepers. ... show more

    • Great mattress, perfect firmness — delivery service needs improvement
Color: White Size: King Style: 12" Pattern Name: Modern Hybrid
I ordered the Zinus 12-inch King Cooling Comfort Hybrid, and the mattress itself is amazing. It feels high-quality, supportive, and perfectly balanced for anyone who doesn’t like a bed that’s too soft or too firm. It arrived quickly, expanded well, and the comfort exceeded my expectations. My only complaint—and the reason for the 4-star rating—is the delivery experience. I clearly requested that the mattress be placed at the back of my house and leaned against the wall because I’m home with a 4-month-old baby and can’t move something this heavy on my own. I also didn’t want it sitting out front where someone could take it. Despite the instructions, the drivers ignored them and left the large box by the front door on a rainy day. There were two men, and from my camera I could see they had read the instructions and still chose not to follow them. The mattress itself is fantastic, but I really wish the delivery service had been more considerate. ... show more

    • Much better results after 5 months than I was expecting. Good buy!
Color: White Size: Twin Style: 12" Pattern Name: Modern Hybrid
TLDR: I'm really surprised how much we like this mattress. Two thumbs up! I highly recommend it as long as you aren't concerned with non-padded sides. We were moving our child from a toddler bed to their first real bed. The toddler bed was essentially a bed frame with a particleboard base and the Moonlight Slumber Little Dreamer foam mattress. First, we started with this bed frame: https://www.amazon.com/dp/B078HZYSG8?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_5. Then I went to the big box hardware store and got a 1/8" piece of plywood to serve as a mattress base. After extensive (ie 10 hours) online searching for a mattress, I decided to go with a 'mattress in a box' instead of a traditional mattress for many reasons. I zeroed in on this Zinus 12" with pocket coils and cooling foam for a few reasons: - Zinus is a known newer brand with a reputation they need to maintain - Sold and shipped by Amazon with the 100-night Amazon return policy backed by the 10-year Zinus warranty - Foam over individually pocketed coils, which we thought would provide the comfort of springs with the foam my child was used to (we bought a much more expensive 'top of the line' solid foam Tuft and Needle cooling mattress for our other child, and honestly after 4 years? meh. Heavy, which makes it hard to change the sheets and worse, it sleeps super hot) - Fiberglass free and claims that they don't use harmful chemicals, OEKO-TEX standards, etc. (I mean, why not if you have a choice?) - Medium firm (similar to the toddler mattress my child liked so much) - Cooling gel (my child is a hot sleeper) - Low price (if my child hates it? Oh well cheap experiment). We bought this in February 2025 and delivery and set up were easy enough. I unfurled the bed in an empty room and within 30 minutes, it was useable, but we left it alone for 5 days. Ever so slight chemical odor that went away after a couple days. My first impressions were that when I moved it, it was light and felt cheap. There are no sides to a 'mattress in a box' and you can feel the springs when you touch the sides. 'Oh well' I thought and proceeded to put it on my child's bed. Seemed really comfortable once you hopped on and were in 'sleeping position'. Easily supports my ~170lbs so it is definitely supportive of my child, who was thrilled with the new bed. Being able to really feel the springs on the side bothered me, but if my kid's happy, that's all that matters. Fast forward 5 months (July 2025) and I couldn't be more pleased with the purchase. My child used to wake up ~1am every single night on the old toddler bed and wander into my room. That has only happened 2x in 5 months. My child thinks it's a super comfortable bed. I do as well. I often lay in that bed until my child dozes off. I have messed up shoulders and always experience pain when laying on my sides in my own bed (super fancy Sleep Number with an adjustable base and the remote controls). I'm also a very hot sleeper and in the summer, I will sweat in the Sleep Number. Admittedly, I myself often doze off in this Zinus bed on my side for a couple hours while putting my child to sleep and wake up with no shoulder pain - and I don't wake up sweaty at all. There are no indentations on the bed after 5 months. All that said, I'm super impressed. It's not a premium feeling mattress, but it gets the most important part done - providing a really comfortable surface to get a restful nights sleep. Once my Sleep Number breaks, I'm going to explore Zinus's 'lux' options at that point for my own bed (perhaps a deep Zinus pocket coil spring and cooling foam on top - and put that on the Sleep Number adjustable platform). I'll come back and update if the springs or memory foam start breaking down, it starts sagging/retaining body impressions, has springs coming out the size, etc. ... show more

    • Great Mattress!

Wow, did not expect any thing from it when I opened the package. It expanded and 24 hours later it was perfect. I like a firm mattress and it is firm. It had no smell, its comfortable, best night sleep I have had in decades. Thank you.

    • Too firm
Color: White Size: Twin Style: 8" Pattern Name: Cooling (New Box)
I've had/slept on a total of four zinus mattresses, and the first two were great, like sleeping on a cloud. Each successive mattress has gotten firmer to the point of discomfort. For me, laying on this one feels the same as laying on a carpeted floor or a yoga mat. It's supportive, but absolutely no give at all. Too firm for a 110 lb person with joint pain. Dimensions are accurate, and it sits well on a metal frame with 12 slats (no bunkie boards or box spring), but I feel bad for any guest who's going to have to sleep on it. It fluffed up within a day, and spending five minutes pulling at the ends with my hands was enough to perk up the corners. ... show more
