ZINUS Narrow Twin Mattress (30” Wide x 75” Long), 5 Inch Memory Foam Mattress for Bunk Beds, Trundles, Youth Bedroom, & Compact Spaces, Medium Feel, CertiPUR-US Certified

I bought A pair of La-Z-Boy couches at an extreme discount because the original customer Backed out at the last minute and they were customized. After a few days I understood why the customer backed out because these are the most uncomfortable couches I’ve ever had. They have the upgraded memory foam seat cushions but There’s large gaps in between each of the cushions. They drove me crazy. For years I’ve been trying different things like yoga mats, mattress toppers, Memory, latex, All things that helped improve the comfort. I finally bit the bullet and decided I was going to remove the seat cushions and buy something to replace it. When I took measurements, I realized I needed a slim or cot sized mattress to fit in the couch frame. Somehow I ended up finding and choosing this one. I was a little worried it wouldn’t fit lengthwise But hearing some of the reviews say that it ran small was actually a good thing for me. It came packaged With extreme care. The directions were a nice touch and made me smile. I took off the plastic and within 10 minutes I couldn’t wait anymore and put it right on my couch. To get the height right I did add bottom layer of yoga mat. Then a layer of foam (in the form of a 4 inch topper I bought on sale) and then this mattress. I then placed a twin sized cooling mattress topper and topped it all off with a fitted cooling sheet. Then I sat down to test it out. Within seconds I knew i finally did it. I was already more comfortable than I had ever been on the original sofa. It was firm like a seat cushion should be & I don’t feel like I was sliding off the end when my feet are on the floor. After I was satisfied it passed the sitting test I tried laying down on it. I ended up falling asleep and had the best sleep on a couch since I purchase those godforsaken couches. I normally wait to write reviews after I’ve used the product for more than a week. However with this mattress, I’m writing this review the day after I set it up. I am so pleased with this setup now. I would call this mattress firm. I was worried about the 5 inches not being enough but I didn’t see a thicker option so I figured I’d tinker with other layers I’d accumulated in the past. Turns out the 5” is more than sufficient and makes it lightweight so that one person can easily move it around. I didn’t smell anything off putting. This seems like a well made product, it inflated quickly, has a protective cover that I haven’t removed yet as per instructions. I am assuming they mean Do not remove the cover while your mattress is in the inflation process. Once it’s fully inflated you can unzip cover and put it in washing machine. I read the cover is resistant to moisture and there’s no crinkling sounds that bothered me. I’m an extremely hot natured person. I use a fan at all times and thermostat set to 69 degrees year-round. . I was worried this mattress would make me hot but that wasn’t an issue. That could be due to the mattress or due to the Cooling mattress cover and fitted sheet I used on top which is also meant to be cooling. TLDR : If you need to rehab a seat cushions on a full sized sofa, and the measurements work for your frame, this is an EXCELLENT option. Not only will sitting on your couch be comfortable, But sleeping on your couch will be wonderful as well. If anything changes I’ll be sure to update.

Could not find a 70Wx75L mattress to fit our Winnebago Era-X RV, and actually thought for many reasons it might work better to have two separate mattresses. Most twins are 39Wx75-80L and most "RV Queens" are 60x75 so when I found these 30Wx75L, I was excited. I didn't expect much from a 5" thick mattress but the 1st night we slept on them, sitting on top of what Winnebago calls their "mattress" (which is just the seat and the back of the rear 3-seater couch flattened out), we were amazed. The next few nights confirmed that they were quite supportive- firm enough to not have the 5" be too thin, but comfy enough to not make it feel like it was an extra firm mattress. And they hid the lumpy-ness of the "sofa" underneath beautifully-I didn't notice any lumps or bumps. Opening the box, there were two clear plastic wraps wrapped tightly around the mattress. They came off somewhat like one of those Pillsbury croissant tubes that release their contents once the pressure is relieved. After that, they unrolled and quickly self-inflated to their 5" thickness within a few minutes. I did not smell the usual smell of most memory foam mattresses, and in fact my super-sensitive wife's nose detected nothing. They were also light enough for one person to carry from the house to the RV easily. We put them in the RV the night we got them and slept on them on our trip the next night. Amazing little powerhouses these mattresses are. And for eighty bucks, I would say this is a fantastic deal.

Good

If I could give less than one star I would. We got this mattress July 25th, 2025 and it is now November 4th, 2025. My 13 year old had a bloody nose this morning and I had to strip the bed to clean everything as it had soaked through. I had heard before about some memory foam mattresses having fiberglass in them, and so I was aware enough to check the tag on the cover before removing it to wash. It did not say to not remove the cover. And maybe if I looked up the names of these things on the tag I would find out that they are fancy names for fiberglass, but I had no idea… We took off the cover so I could wash it and because my kid, being a hilarious 13 year old, brought the entire mattress down the steps saying “you said bring down EVERYTHING that had blood on it…” we not only removed the cover right over all of the bedding that was previously brought down, but also over the carpeted stairs. I helped bring the mattress back up and we plopped it down on the bed slats that have OPEN GAPS to the drawers beneath. I first saw how tore up the top of the mattress was and was surprised… then saw in the light of the room, the shiny fibers that were everywhere covering the mattress. I knew in that moment that this was going to be a big deal. Everything that mattress touched or was near is now covered in fiberglass, including ALL OF THE CLOTHES that are in the drawers under the bed, the furniture that we passed going back into the room, the carpet, what we were wearing, our skin, and our poor dog. The mattress is less than 4 months old. This is absolutely ridiculous. I googled to figure out what to do and it looks like there has been a lawsuit/ lawsuits against this brand (Zinus) because of this, although I have not confirmed. Be warned. It is not worth it. Would NOT RECOMMEND.

We put this mattress on a kid's bed and it fit the frame well. It expanded nicely after unboxing and feels comfortable. Good value for a memory foam mattress.

In the description, it said this mattress was great for a trundle bed. But it is way more narrow than I thought.. it works for what I need, but I wish that I had done a little more research on trundle bed mattresses

i built a bed frame for this mattress inside a camper van and it is incredibly comfortable. instead of slats beneath the mattress, i used straps (old seatbelts), and it worked great. however, i was visiting a friend and thought i could use this mattress on their floor, but it was not nearly as comfortable. therefore, i would not recommend this mattress for use on a hard/flat surface. it's just not thick enough. it needs some spring or flexibility beneath it, especially if you're a side-sleeper like me. however, for the bed i built, i could not be happier. it's perfect. would purchase again. ymmv

I’m really impressed with this mattress. Low cost - high comfort. I got it to replace a very old and shabby mattress in a used sofa bed. The mattress was an odd sized that was hard to match. This one fit perfectly in the frame. It took about 48 hours to fully expand. Odorless and comfy. I’m very happy with my purchase.

Es un producto de excelente calidad, es muy cómodo y suave. Fue fácil abrirlo, el colchón recuperó su forma original en menos de 5 min. Es algo angosto por si buscas tener el espacio de una cama individual promedio, aún así funciona bastante bien para adultos. 10/10

Parece de muy buena calidad. Está mucho más cómodo de lo que imaginamos. Además se puede lavar fácilmente.

Works great. I slept on here for three weeks, no complaints. At 185 lbs I didn't have any problems with bottoming out. It took a few days to fully expand when unpacked, but it did eventually achieve a full 5" thickness. The mattress is comfortable.
