ACX is the tenth swivel office chair that Vitra has developed in collaboration with Italian designer Antonio Citterio. With its automatic synchronized mechanism that adjusts to different weights, ACX offers maximum comfort for all users and is made largely from recycled materials and is recyclable.

Its backrest has a knitted fabric cover. The semi-transparent mesh fabric is made from recycled polyester and is available in various colors which, combined with a light or dark frame, allow for different looks.
