If you weigh 90kg+ don't buy it. It's like sleeping on the ground. I used it once and luckily I had brought another one with me. I gave it away because no one was buying it

I went to see it up close before buying it. From the beginning, I want to say that I need it for a backpack and hiking, which means weight and volume are equal to everything. As soon as I saw it, I said forget it, not even close. It seemed like a good product, but its volume was discouraging!

Quite good!
For a person weighing 100+ kilograms with a body shape beyond average, it held up quite well.
Perhaps every morning you should let it refill with air, just like the pillow from the same company.
With a good sleeping bag, you won't notice anything.
Update: After a week of use, the bottom part of the legs started to fade in color in some areas, maybe from rubbing against the pillow(?). Despite that, it did its job.

It is comfortable and lightweight, relatively small in volume considering its thickness. Whether it is durable remains to be seen.

Easy to use, comfortable sleep (adjusting the mattress firmness as you prefer), high-quality product.

Comfortable and inflates immediately. Quality materials, soft surface on top and rough underneath to prevent slipping. It is quite bulky when packed due to the filling, but that's why you can sleep comfortably without air.
Both the mattress and the corresponding pillow I have lose air from the glue on the valve, which was fixed with a little glue. It requires a lot of attention when opening and closing.
