ACX Light

ACX Light
by Vitra

Designed by
Antonio Citterio
for Vitra 2023

ACX is the tenth office swivel chair that Vitra has developed in collaboration with Italian designer Antonio Citterio. With its automatic synchronised mechanism, the compact ACX offers maximum comfort for every user without any need for adjustments other than seat height – while exhibiting a distinctly non-technical appearance.

ACX Light is the entry-level model in the task chair family and available only in black. It differs from ACX Mesh and Soft through its backrest, which has a standard netweave cover. Combined with a seat in the technical spacer fabric Silk Mesh, the chair is designed to offer pleasant comfort and facilitate air circulation.


Available in Black Nero, and Deep Black Frame.


Seat mechanism: synchronised mechanism with automatic weight adjustment and two backrest resistance settings (hard or soft). Equipped as standard with seat height and seat depth adjustment. Optionally available with or without synchronised forward tilt (can be disengaged). Mechanism can be locked in upright sitting position. Seat mechanism matches frame colour (deep black).

Seat upholstery: polyurethane foam. Seat cover in Silk Mesh spacer fabric, colour nero.

Backrest: back frame with semi-closed shell and transparent netweave cover. Frame made of polypropylene in deep black. Optional height-adjustable lumbar cushion.
