The air mattress is filled quickly by itself with air and is thus quick to use. This is the only 3 cm thick, but only a light child can lie on it. If an adult or an older child lie down on it, it lying on the ground, because the mattress gives way. I have this mattress 2 more times, but in 6 cm thickness and that's really great of comfort. The mattress can be super Curled and transported again.
