ZINUS 5 Inch Twin Cooling Essential Memory Foam Mattress [NewVersion], Fiberglass Free, Medium Feel, Breathable Cooling Layers, Certified Safe MaterialsOEKO-TEX STANDARD 100

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.

I bought this bed because it was a more affordable choice than most Of the other new 12 inch memory foam queen beds I’d found online. I read a lot of reviews and looked at a lot of pictures as well.The bed was shipped to me very quickly about a day. The packaging was a bit torn up but the bed wasn’t damaged. I got it upstairs, unboxed it, it inflated rather quickly, but I still waited a full 24 hours before using it to make sure it had fully inflated.I measured it and it was in fact 12 inches in thickness as advertised once it fully inflated. I had a 3 inch memory foam mattress topper I purchased a few years ago that I put on it for added cushion because I’m a heavier woman.I haven’t slept this well in 4 years and I haven’t been waking up with aches and pains like I was before. The bed is very firm and provides a lot of support in my opinion. I’m currently pregnant and this mattress is definitely light years better than my old one.There was no weird smell. It’s quiet when I get on and off the bed. Also oddly enough I haven’t felt that strange sensation of falling off the bed while dozing off since I got it. Maybe because it holds my shape really well. Not sure.I highly recommend this mattress to anyone who wants a quality mattress for a bargain.

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 tooIt’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.
