As much as 50-80% of timber is wasted during normal manufacture. Together with designer James Shaw, Marjan van Aubel discovered that a curious chemical reaction occurs when mixing timber waste with bio-resin: It expands into a strong, foam-like material almost twice its size.

Using a variety of different sized shavings collected from workshop floors and mixing with coloured dye, they were able to create a colourful, lightweight and moldable material that is reinforced by the fibres in the hardwood shavings. In Well Proven Chair, the mixture expands around the leg structure, leaving behind evidence of its exuberant material behaviour once it sets.
