The product performs well, and the valve seems well-designed. I weigh 87 kg, and it supports me without bending. It will touch the ground if my knee bends, like if I were to run. However, it's comfortable and supportive in standard lying positions. I plan to test it in actual summer conditions.

The price is excellent for the quality! I paid 33 euros! Inflation isn't handled perfectly and it doesn't keep the weight very well, but the sponge inside helps! It's worth what it costs!

The carpet is light and pretty. The silicone inscription was pleasing.

Flawless and pleasant
