ACX Mesh

Antonio Citterio, 2023

ACX Mesh differs from the two other models in the task chair family – ACX Light und Soft – in that its backrest has a knitted fabric cover. This semi-transparent mesh textile is made of recycled polyester and comes in a choice of seven colours – which combined with either a dark or light frame enables numerous variants. The seat cover can be selected in a complementary knitted fabric or in the textile Plano.

ACX is the tenth office swivel chair that Vitra has developed in collaboration with Antonio Citterio. With its automatic synchronised mechanism, the compact ACX offers maximum comfort for every user – while exhibiting a distinctly non-technical appearance. The construction, materials, production, logistics and maintenance of ACX are designed to achieve a long life cycle with the smallest possible carbon footprint. The ACX mechanism automatically adjusts to a wide range of user weights: even lightweight and heavier individuals can sit down and enjoy instant comfort and optimum support throughout the full scope of movement, without having to adjust anything except the seat height. That makes ACX particularly suitable for environments in which dynamic collaboration processes have replaced sitting for long periods in the same chair. The design of ACX features a limited number of components, which simplifies service and maintenance. The parts are made of recycled materials whenever possible – up to 60% depending on the model – and can be easily separated and recycled again at the end of the product's life. Depending on the chosen model, ACX is therefore up to 100% recyclable. ACX has a casual and relaxed appearance: with its clean lines and choice of knitted fabrics in a wide selection of colours, it functions as a design element in the office – instead of a necessary addition tolerated for the purpose of ergonomics. ACX is the ideal chair in any setting that calls for healthy ergonomic seating with an understated inviting aesthetic along with a focus on longevity and compliance with stringent ecological standards. ACX is available in three versions: ACX Soft, ACX Mesh and ACX Light.
