A chair made only of wood

This chair consists exclusively of wood, without glue.
The joints are made with a new wood-joining technique, the ‘rotation dowel welding’ technique. The heat generated by placing the dowels releases adhesives present in the wood itself – lignin and hemicellulose – forming a substantial welded bond in seconds.
In association with Sebastian Kraft from the Biel School for Wood Technology (BFH –AHB) this new kind of chair was produced.
The chair was designed with the technique in mind. The overlaps required for the welded bonds and the wing-like construction are characteristic features of the ‘JWC’ lounge chair.

Material: 100% beechwood = 100% Postfossil
