Perfect. I got it for the beach with pebbles. I put it on top of the mat and it feels like I'm on my bed. Extremely comfortable. Who needs loungers and nonsense. Buy it with your eyes closed, you'll remember me. And one more plus is that it's foldable, you can take it with you holding it by 2 straps - handle.

Very comfortable, the weak point is the seams, but with proper use, there won't be a problem.

Edit: After some time, the foam in the middle starts to sag a bit and it's not the same. The good thing is that it has a zipper and one can replace them. I think with a simple mattress topper or rug on top, it will be fine

Excellent product. My daughter uses it for exercise, to lie on it on the floor, she uses it inside her tent for camping, etc. It has been very useful to us in many cases. I would definitely recommend it.
9/2/2019: Unfortunately, after relatively prolonged use, I renovated my house and slept on the floor using this mattress for about a month and a half, and from the first week it became as flat as a sheet. Obviously, the foam it contains is of poor quality. It is only suitable for very occasional use. Therefore, I feel obliged to inform and change my review to negative. I do not recommend it.

Good choice because it is 4 centimeters thick and made of soft material, it tears easily, so if you open your legs and stretch it outward, the seams will open, so now I only use it for abs
