The idea of using waste materials within the body of a chair is appealing, although the need to select the materials carefully would limit the amount that could be used. Shavings from different timbers give different effects – for instance, cherry shavings impart a definite reddish hue. 

The biggest uncertainty is with the bio-resin. Although claims for these materials say that they are more environmentally friendly than conventional resins, very little clear data is available. Van Aubel and Shaw have used the resin in a very different way from the manufacturer’s recommendation and so it is hard to judge how durable the chair will be. It is very much a ‘work in progress’ and the pair are eager to continue their research.
