During development of the design, Guerrero Font managed to slim down the thickness of the timber from 20mm to 12mm. ‘I realised that the complexity of the chair lay in making the jigs,’ he explained. ‘I learnt a lot about ways to work with wood at Benchmark that I hadn’t even thought about. Just having an idea and drawing it is very different. There are so many different solutions you can use to make one thing. You have to learn which is the most accurate.’

By choosing American ash, one of the strongest timbers, Guerrero Font has managed to slim down his initial design and so use less wood. Since most of the effort involved was in making jigs that could create the simple-looking but difficult joints, this would be a relatively straightforward chair to make. The jigs would be reusable, and the making of repeated chairs would involve relatively small amounts of energy.
