I've been sleeping on floor mattresses for over 15 years. This is the best. I've tried the cheapest "MLILY" to the more expensive "Milliard" brand trifolds here on Amazon. They're all incomparable with the Quicksleep. This is pretty much an actual bed that can fold. It has springs! I don't know how they managed to do that because it ships compressed into a roll the same way other trifolds come in. I'm actually happier and more positive as a person because I get such restful sleep with the Quicksleep. The problem with the other trifolds are that when laying down, the foam will depress and eventually start to put pressure on your body. They also get hot just by their nature as dual use insulation. This has none of the problems. Easily one of the best purchases in my life. For minimalists, look no further, this is it.

This is probably the best thing I’ve bought for myself. I want to thank the manufacturer, quick sleep from Korea, for making this product because it genuinely improved my quality of life. This mattress is portable, folds in 3 very easily, just the right thickness at 5 inches, as comfortable as any mattress I’ve tried and bought from ikea ever, and just overall a great purchase. I’m a full time van lifer, and finding a comfortable mattress that can be folded up for storage is important for me because I don’t want a mattress to take up 50 percent of my small space even during day time when I’m not using it. Most mattresses you can find in stores won’t work for me because they can’t fold. So I’ve resorted to sleeping on top of 3 mattress toppers, each 2 inches thick. While my “mattress” can fold, my sleep quality has been very bad compared to when I was sleeping on a regular mattress in a house, because mattress toppers are just foam, and foam sinks. I would always wake up with my back as well as my neck hurting. Just as I was about to purchase a Japanese futon, which would’ve cost me several hundred dollars and routine maintenance due to it being cotton, I discovered quick sleep on Amazon. I immediately knew this is what I want once I saw that it has springs inside, instead of being just another big piece of memory foam. Springs provide the kind of support that is a night and day difference from what you can get with memory foam, and it’s a different kind of support from a futon, which is rock hard. If I want rock hard I might as well sleep on the floor. This mattress is perfect; it’s house grade. Oh, and did I mention that it can fold into a sofa? How nice is that? The only thing i didn’t quite like about the mattress is how darn expensive it is. But I’m not complaining; it really brings a dramatic improvement to my quality of life so I would buy again even if the price was higher. TLDR, if you are looking for a portable mattress that isn’t just a piece of memory foam, and feels as comfortable as a house mattress, you’ve found it. Just buy it.

I first heard about this brand through a recommendation from a friend in Korea. It's a very famous mattress brand there, and after using it, I can see why it's so well-known. I enjoy inviting friends over to my place, so I was looking for a mattress that’s easy to store. This folding mattress is perfect because I can fold it up and store it when not in use, saving a lot of space and being very convenient. After using it myself, I found that it has no odor, and the quality, including its thickness and softness, is excellent. It provides just the right amount of support, so even after sleeping for a long time, my back doesn’t hurt and I get a comfortable night's sleep. The thickness is also perfect, providing warmth and coziness without feeling the cold from the floor. Additionally, I can use it as a topper on my old mattress, which makes it even more versatile and useful in many ways. The packaging was perfect. It arrived very quickly, and it was securely wrapped in plastic, ensuring it arrived safely without any damage. My friends who came over to my house were all impressed and ended up purchasing one for themselves. I highly recommend(x100000000) this product to everyone. It’s absolutely fantastic!

I've always thrown a twin sized on the back of the car rear seat laid down, but modern twins are always made form the cushion material companies call "therapeutic" or "memory foam" but it's not, it's crap and doesn't hold its form. This one actually has coils and folds up in the trunk. Also twins don't really fit in the car but this one is just right fits perfectly. It's also hard to store regular twins so the folding is great at home in a closet. You don't want to fold a regular twin in half because then the middle becomes bent and breaks your back. Only CON is that it's pretty hard, at least for anyone over 35 -40. In my 20s I'd sleep in pretty hard mattresses at national parks, now I really can't. I bought soft topper, which surprisingly was hard to find a good one, the e"egg crate" ones have changed over time to useless foam material. I found that bamboo brand one here on amazon the best topper for it.
