Zinus 5 Inch Twin Cooling Essential Memory Foam Mattress [NewVersion], Fiberglass Free, Medium Feel, Breathable Cooling Layers, Certified Safe Materials

I was a little unsure about a 5" mattress, but this one really surprised me. Even though it’s thinner, it feels just as supportive and comfortable as thicker mattresses I’ve owned. It has a slightly firm feel, which I personally prefer, and it holds its shape really well. With some 5" mattresses, you can feel the platform or slats when you sit or lie down but that’s not the case here at all. This one feels solid and well-made, without any sinking or bottoming out. I’ve been sleeping comfortably and wake up feeling well supported. The price is phenomenal for the quality, and it honestly made me rethink traditional mattresses altogether. I’d never go back after this. It’s been a perfect fit for my low-rise platform bed, and I’m very happy with this purchase.

I have the 12" and the 6" for myself and my toddler. They are both on the firm side, but not "like a rock" as other people have mentioned. If you're used to a super soft bed it will likely feel pretty firm initially, but it gets more comfy over time, in my experience. I prefer to let mine sit in a room to get their shape back for a day or two before use. I thought I liked a very soft bed but it turns out I like the medium-firm memory foam better. There was a slight off-gassing smell the first 24 hours, easy to open a window and turn a fan on. These are incredible quality mattresses for the price, door delivery, and ease of set up.

It is what it states it is !! Excellent quality. Firm but not hard. Very comfortable. Doesn't have horrible smell like some products have. Actually no smell at all. Definitely recommend!!

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.

A little firmer than I wanted but it works just fine. My hips dont hurt every morning when I get up

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.

Delivery was on time. Bought the mattress for my son, it took 4-5 for the mattress to get to the shape. Mattress was firm and son is having comfortable sleep. Same mattress i saw in store 4 times more expensive, for the price and quality it is a great find.

I'm happy with it. So comfortable and easy to carry. I suggest this if you are low budget. Good value for price.

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

Superó mis expectativas

I have been sleeping on this mattress for over a year and a half now. It really is a great product and I am very glad that my friend told me about this. It's comfortable to sleep on and the firmness is just right. It's also not as bulky as some other mattresses which is a huge plus when doing laundry, as I make use of fitted sheets. No complaints at all.
