Shell in plastic composition with up to 25% wood fibers. Pipe bottom is made of Powder coated steel or chromed Steel. The wood fiber and plastic mixture is injected into the mold and forms the shell of the chair. The inside of the shell is then padded with foam and fabric. The fabric is glued to the surfaces of the shell and adhered by means of a tube on the edges for a smooth and dense surface of the fabric. Clean the shell with a damp cloth. If necessary, use a little detergent on the cloth. For the upholstered seat, you can find cleaning instructions for your chosen textile at Kvad.dk. For versions of leather upholstery, clean the leather with a dry cloth regularly. Treat the leather at least four times a year by using only special leather treatment products for aniline leather.
