ACX Soft
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 Soft stands out from the other two models in the ACX family – Light and Mesh – in that its backrest has a padded knit cover. This soft comfortable textile made of recycled polyester lends the task chair a particularly inviting appearance.


Also available in a selection of Vitra fabrics and leathers. Please enquire for further information.
