RE designates the HAL model with a seat shell made of recycled plastic. Utilising this recycled material from household waste instead of conventional plastic generates less climate-damaging emissions, with a reduction in energy consumption. Due to the composition of the recycled material, the different colours are interspersed with tiny specks of pigment, giving the seat shells a certain natural appearance and a warm inviting appeal – especially when combined with the characteristic wooden legs in the version HAL RE Wood.
