Excellent mattress! I bought both the twin and queen to replace older mattresses for relatives. The twin was for a 25 year old and the queen is used by a 60 year old. The older relative said her back pain disappeared! The younger one was doubtful at first and ended up saying it was surprisingly comfortable! I really like the fact that it is foldable with a case and I could carry it by myself, it makes moving it a cinch! I think it is a great buy especially for an apartment, it could be folded up and fit in the back seat of a car by one person

I got this floor matress for 3 reasons. 1) it's foldable and I can store it out of the way 2) It is easier for me when I have routine procedures to rest on the floor with a wedge pillow 3) I wanted to be able to sleep with my senior dog again because our king bed is too high and I'm fearful he will fall off potentially hurting himself greatly since his vision isn't great. Right off the bad, it's pricy. The price of a regular good comfortable twin mattress. However, if I buy a more affordable one that lasts a few months then I end up having to purchase a better one later and that may end up costing me more. So i decided to got with the best first for quality and longevity. I am happy I purchased this. Been actually sleeping on it for a week with my senior dog. I did however add a soft padded mattress pad on top it to make it even more comfortable. I don't feel like I'm sleeping on the floor. It's firm and as soft as I make it to be with blankets etc. I have back and neck issues. I haven't had any added pain from sleeping on it. I've become quite lazy and rest on it instead of sitting on my couch. My Yorkie is a small guy. 4 lbs tops and he has some trouble getting up the 5 inch plus 1 Inch mattress topper so I prop his beds along the side of it and he's able to hobble on top of it. Overall, very happy this purchase. When I'm done using it I plan to give it to my parents for their twin bed in their guest room as a topper. If any sales, jump on it!

After some research, I decided to purchase this folding mattress for a family member’s upcoming visit. On paper, it fits the bill: high quality and space saving. We were not disappointed when we received it. It had no smell and felt very comfortable, though we only lay on it for a few minutes. The mattress came with a carrying case. But it was defective. After messaging the seller, a replacement was sent to me very quickly. The real test will be done by the guest. I will update my review after their visit.

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'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.
