Finally a good night sleep. Very comfortable mattress. Medium firmness. It was easy to take out of the vacuum sealed bag. You should leave it 72 hours before using for the it to expansion back to its normal size. It is very comfortable and have good support for back. Good functional and comfortable mattress for the price paid. Definitely a good value for the money. I guest the only question would be how long would it last before needed to purchase a new one .. only time will tell. I will put in another review after few months of use.

I recently purchased a firm queen-size mattress, and it has exceeded my expectations in every way. From the moment I laid down on it, I could feel the perfect balance of support and comfort. The firmness level is exactly what I was looking for—sturdy enough to provide excellent spinal alignment while still having a slight cushioning effect that prevents any pressure points. Whether sleeping on my back or side, I wake up feeling refreshed and without the stiffness I used to experience with my old mattress.

The media could not be loaded. I was a little skeptical at first because im used to firmer beds, but this KOULABRZ mattress has totally won me over. Its soft enough that i feel like I’m floating. But somehow still supportive. I’ve been waking up feeling refreshed, and the mattress just feels like it molds perfectly to my body. Its not too firm, not too soft-just right. Plus it fits perfectly in my room and looks great! UPDATE:After using the mattress for a month, I’m even more impressed. The initial floating softness I loved has held up perfectly—no sagging or changes in support. It continues to mold to my body and feels like it balances comfort and firmness just right. My mornings are noticeably better; I wake up refreshed and without any aches, which I didn’t realize was even possible before. The mattress also regulates temperature well—I never feel too hot or cold, which is a bonus. It still looks as good as new and fits seamlessly into my space. Overall, it’s been a fantastic investment, and I’m glad I made the switch!

Really good mattress! No smell or odor! It’s super comfy and big. I would says its a good medium between soft and hard. I got the correct size and it arrived a day early. Overall, if you are anything like me and overthink everything I would recommend getting this mattress. I’m 5’1 and around 190 pounds and my boyfriend is 5’11 and around 210 pounds and we fit comfortably and easily. 100% recommend!

Bought this bed for my adult son’s former childhood bedroom. It was a great price and the thickness of this mattress is nice. The mattress inflated beautifully and seems comfortable. My biggest concern with buying a condensed mattress on line was side stability. The sales material claimed to and provided pictures of stabilized edges. The edges are reinforced on the upper part of the mattress, up to about where you would sit to get in or out. However, after that, the side and bottom edges are soft and you slide off it you try to sit anywhere on the end of the bed. I am waiting for a guest to test out sleep-ability. Gas the sides been reinforced all the way around, I would have given it five stars.

It's comfortable, but not has firm as I hoped. Not comfortable for 2 people. I'm thinking about taking it back. It's not sturdy to sit on the side.

Picked up the 12-inch queen size at a great price, and it’s definitely worth it! Heads up, though – the box is super heavy, so you’ll need some muscle to get it in place. Once opened, I could tell the materials and build are high quality. I noticed it has denser pull points in the middle, probably for added support around the waist area, which is awesome. I marked it for myself so I know exactly where to align when I sleep. I’m around 200 lbs and usually toss and turn a lot, but since using this mattress, that’s pretty much stopped. I sleep on my side and haven’t felt any soreness or discomfort, which is new for me! My back feels supported and aligned, and the mattress feels even all the way through. Love that it has handles on the side to help move it too – makes handling a lot easier. I came from a medium-firm plush mattress that was always too hot and lacked support. This one really does the job right. Highly recommend for the price!

Do not trust their claim of returns or warranty! I contacted them the week we received the mattress with an issue. The edges are much lower than the center, and it feels like you'll roll off the side or when laying normally, your arms slide off the edges of the mattress. I sent pictures to prove this (see attached). They agreed that they wanted me to be satisfied with the purchase and quality, and would investigate how to handle the situation. Customer service seemed great, BUT they never replied after that! I contacted them 2 more times, and they totally ghosted me. Sadly, the mattress itself is pretty comfortable, but I would avoid this company altogether because of their false claims of returns if not satisfied.
