With the free-2-move concept, developed by Trimension®, Wilkhahn sets the global standard for a healthy, three-dimensional mobile chair. With its integrated and balanced design, variety of models, and individual equipment options, the AT program is the intelligent all-rounder among the FreeMotion programs: the self-centering seat suspension ensures safe body balance in all postures and movements. And because the tilting backrest is coupled with an automatic weight adjustment mechanism, the AT chair makes mobility healthy: sit down, adjust the seat height, and go! Everything else is done by the body and the chair...

In addition to standard-height and raised-seat office chair models, AT also offers a box chair model with a height-adjustable ring. These models are used not only at counters but also in modern project rooms so that participants can sit at the same height.

At the heart of the AT chair is the synchronized 3D kinematics support called Trimension®. The suspension, automatically centered in the seat base, is combined with an automatic weight adjustment mechanism (so users don't need to adjust the AT to their own weight) and optionally features a preset function to suit personal preferences. This activates the natural range of motion of the human pelvis, including flexion, extension, tilt, or rotation. Synchronized forward and backward movements allow for a tilt angle of up to 12° for the seat and up to 26° for the back. AT also features an optional 3D forward tilt of up to -5° that can be activated, allowing the backrest to synchronously raise by 25 mm so that lumbar support always remains in the correct position. The seat and backrest can be tilted laterally from horizontal by up to 12°. This automatic feature also comes with an optional preset in ten increments to suit personal preferences. AT is suitable for people weighing between 45 and 140 kg.
