  • Good mattress!!
Size: Tw"
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. ... show more

  • Totally worth it!
Size: Tw"
I needed a mattress for when my family visits, so I was looking for one that could be easily folded for storage when not in use. Since our house isn't very big, I was looking for one that could fold up but still be reasonably firm. It was difficult to find a suitable product, but then a friend of mine in Korea recommended this product, and I decided to check it out on Amazon just in case. Despite having left Korea a long time ago, I found out that this brand was actually very famous there. I received the mattress, unfolded it, and started using it the next day, and the quality exceeded my expectations. Firstly, the mattress is heavier and thicker compared to other products. When lying down, it's not too soft and provides just the right amount of firmness, which supports my back very comfortably. Until now, I've been using a relatively cheap mattress in the guest room, but this mattress is so comfortable that I want to use it every day. Additionally, it can be folded and used as a sofa, making it very practical. During the week, I fold the mattress and place it like a sofa in the kids' room to read books, and in the evening, I unfold it so the kids can sleep there. Folding and unfolding is easy, and the storage bag is great for keeping it clean in a narrow space. I think I'll need to buy another one for the guest room; this has been the most worthwhile purchase I've made recently. I highly recommend this product to my friends. ... show more

  • 🌙A Nighttime Savior: The Ultimate Foldable Mattress for Family Comfort
Size: Tw"
As a parent, I understand the unpredictability of nighttime routines. There are nights when my kids wander into our room, seeking comfort and company. This led me on a quest to find a solution that would ensure their comfort and mine. As someone with a bad back, I needed a mattress that offered good and even support. My search led me to this brand, highly recommended by a friend and renowned in Korea. The first thing that struck me about this mattress was its foldable design. It’s compact when folded, saving valuable space in our room. But the real magic happens in the middle of the night when it unfolds easily and quickly, providing a comfortable sleeping space in no time. This feature has been a lifesaver, especially during those unexpected midnight visits from my kids. What sets this mattress apart is its dual hardness feature. It offers two different levels of firmness - soft and hard. Both options provide excellent support, thanks to the independent springs. This feature caters to different comfort preferences and is particularly beneficial for my back. The soft side offers a plush, cloud-like feel, while the hard side provides firm support that helps maintain proper spinal alignment. This versatility is something I haven’t found in other mattresses. Another aspect I appreciate is the quality of the materials used. The mattress feels durable and well-made, which gives me confidence that it will last for years. Plus, the cover is easy to remove and wash, which is a huge plus for maintaining hygiene. In conclusion, if you’re considering getting a foldable mattress, I highly recommend this one. It’s more than just a mattress; it’s a solution for nighttime comfort for the whole family. It’s a product that truly combines convenience, comfort, and quality in one foldable package. Whether you need an extra bed for guests, a comfortable spot for your kids, or a supportive mattress for your back, this mattress checks all the boxes. + One tip I’d like to share is about the positioning of the mattress. When you use this mattress, I recommend positioning the connecting joint upwards and towards your upper body side. I’ve found that this gives better support and enhances the overall comfort. ... show more
