Ronan and Erwan BouroullecÔs interest in organic shapes already manifested itself in 2004 with the design of Algues for Vitra. Based on these experiences, the two brothers collaborated with Vitra over a period of four years to develop Vegetal. The process involved countless prototypes and an intense exploration of injection moulding technology. The goal was create a chair that aspires to look like natural vegetation while simultaneously incorporating the necessary strength, stability and comfort. The flat, branch-like ribs are asymmetrically intertwined on three levels to form the seat shell, which is shaped as an irregular circle and supported by four legs that appear to sprout from the ground. Vegetal is available in six colours that are unusual for plastic chairs, emphasising the underlying concept of replicating structures found in nature. It is suitable for indoor or outdoor applications and can be stacked up to three chairs high, which permits flexible use in a variety of settings and in large numbers. The chair is manufactured using a highly energy-efficient process and is made from 100% recyclable polyamide.
