JWC 1+2
Concept
This chair consists
exclusively of wood, without glue. The joints are made with a new wood-joining
technique known as the “rotation dowel welding” technique. The heat generated
by inserting the dowels releases adhesives present in the wood itself – lignin
and hemicellulose – forming a solid welded bond in seconds. The new kind of
chair was produced in association with Sebastian Kraft from the Wood Division
of the Bern University of Applied Sciences in Biel/Bienne (BFH – AHB), and
specifically designed with this particular technique in mind. The characteristic
features of the JWC lounge chair are the overlaps required for the welded bonds
and the wing-like construction.

An evolution of the chair made solely from wood, the Just Wood Chair 2 is a refinement of the world’s first exclusively wood chair using an applied wood-joining technique, obviating the need for glue to assemble it. The heat generated by inserting the dowels releases adhesives present in the wood itself – lignin and hemicellulose – forming a solid welded bond in seconds. The constructive design of JWC2 plays with separations and connections, formal amalgamation as well as a chequered design. Up to four of the chairs can be stacked together.
Context
A chair made only of wood.
Material
JCW 1: 100% beech wood = 100% post-fossil.
JCW 2: Ash, maple (dowels). Colour: reaction of the wood with iron oxide and tannin.
