The first inflation (when she was curled longer) you have to wait about 2 minutes and a-two times drauflegen until it is fully inflated. Then the whole process starts, however, in about 20 seconds.
It is very comfortable on the mattress and it also insulates well from cold floors (even in the rain and very cold floor was not cold in a thin sleeping bag!).
The only drawback: the specified size of 200x66x7 is not really down. Through the welded edge, the mattress is inflated actually only 190x60x5. Since I am 191cm tall, I am therefore of the toes. If anyone over 190cm tall I therefore recommend to order a longer variant.
Otherwise, top product, the material is very high, enclosed are two tensioning straps and a storage bag, goes Curled (from the second time;)) very easy.
