The mat is extremely thin and light and therefore does not provide suspension comfort. The insulating effect, however, is very much felt. Since the surface is easily washed off, the thing also as place mat (picnic to dry things, etc.). The aluminum layer is surprisingly robust and scrolls so far not from. Carrier material is not soft foam, but a kind of thin Styrofoam. This makes the mat unfortunately quite stubborn when spread or rolling. Overall, for the price but a nice thing as Ergänzung- or Notmatte or just for people who are tough.
