Zinus 10 Inch Twin Cooling Essential Memory Foam Mattress [NewVersion], Fiberglass Free, Medium Feel, Breathable Cooling Layers, Certified Safe Materials

Firmer than expected, great value with a warranty!
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.

Great mattress, perfect firmness — delivery service needs improvement
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.

Nice
I bought two of them. Inflated quickly. Decent for the money. Good quality. Is a hard mattress.

Much better results after 5 months than I was expecting. Good buy!
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.

Vino muy aguado es de 8 pulgadas de grosor,no me gustó,tuve uno hace tiempo de 6 pulgadas de grosor y me encantó está muy bueno el colchón pero esta vez no me agrado, gracias

I really like this mattress. I’m used to rock-hard mattresses, so I had neck and back pain for a while, but since I started sleeping on this one, I haven’t had any problems. Although it’s thinner than I’m used to, it works very well and is very comfortable. My bed frame is made of steel, but you can’t feel it at all with this mattress.
