The Aluminium & Leather chair concept has been designed sustainably. The aluminium frame is elegant, and modest. While the leather seat and back rest make this a luxurious comfortable chair. Researching human anthropometric data, played a huge role in the planning of this chair. Furthermore, working in unison with the 'Journeyman' chair test rig, each measurement could be tested throughout the design process to achieve absolute comfort. Crafting the frame dimensions to fit 95% of the human population.
