Now have the folding chair from Camp 4 and ADAC bought. The construction principle is the same. In Camp 4, the frame appears to be slightly better stabieler and processed. The seating comfort on the other hand I like better in the ADAC-chair. The reinforcing belts run at Camp 4 crosswise under the seat which creates an uncomfortable pressure distribution. From the pack size of the chair is also suitable for transport on a motorcycle. The complete reference läst be removed without tools and is therefore stowed separately.
