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 main feature is the backrest, which has a quilted knit cover. This comfortable and soft recycled polyester fabric gives the chair its particularly inviting look. Available in various colors, it can be paired with a light or dark frame, allowing for a wide variety of configurations.
