ACX Soft

Antonio Citterio, 2023

ACX is a compact task chair whose automatic synchronised mechanism offers optimum ergonomic comfort for different-sized users – without them having to adjust anything except the seat height. Despite these complex technical functions, ACX has a simple understated appearance with clean lines. The construction, materials, production, logistics and maintenance of ACX are designed to achieve an exceptionally long life cycle with the smallest possible carbon footprint.

ACX Soft stands out from the other models in the ACX family 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. Available in a choice of seven colours, the knitted fabric can be combined with a light or dark chair frame, allowing for a wide variety of configurations. 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 self-regulating 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 and lumbar support instantly adapt to a wide range of user weights: even lightweight and heavier individuals can sit down and enjoy immediate 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 covers of all models can be easily removed and replaced. All parts are made of recycled materials whenever possible – as much as 60% for certain models – and can be easily separated and recycled again at the end of the product's life. This also applies to the new V-Foam used in the seat cushion, which is the world's first recyclable polyurethane foam. As a result, ACX is up to 100% recyclable, depending on the chosen configuration. ACX has a casual and relaxed appearance: with its clean lines and choice of knitted fabrics in a variety of colours, it functions as a design element in the office – instead of a necessary addition tolerated for the sake of ergonomics. ACX is the ideal chair in any setting that calls for healthy ergonomic seating combined with an understated inviting aesthetic, a focus on longevity and compliance with rigorous environmental standards. The product family includes a number of different versions: ACX Light, ACX Mesh, ACX Soft, ACX Pad, ACX Pad High, ACX Softknit and ACX Softknit High.
