Notice : I used to sell this manual and patterns but now I am offering them for free,
so some remarks in the manual about 'further information' and 'refund policy' are not applicable anymore.

Indoor stool 'Kraftwerk' (2008) weighs just under 4 lb, and to keep it’s structure is filled with
CFC-free polyurethane expansion foam bottles, allowing it to hold up to 209 lb.

The chair uses only 4 mm cardboard thickness, foam and 2 wall brackets.
Its name arises from the use of cardboard and kraftpaper-tape.

Weight : 1,8 kg / 3.97 lb
Maximum load 95 kg / 209.4 lb
Dimensions : W×H×D : 510 × 844 × 566 mm / 20.08 x 33.23 x 22.28 in
