Wilkhahn AT 187/71 Mesh Task Chair

The AT mesh chair from European market leader Willkahn, loaded with ergonomic features, a stunning white and grey model and the unique Trimension patented technology for three dimensional, synchro-adjusted dynamic seating.

We all spend long periods of time in hunched positions at our desks, but what the human body actually requires is frequent and a varied range of movements, so the AT chair uses Trimension patented technology for three dimensional, synchro-adjusted dynamic seating.

What is Trimension:

Trimension doesn’t just encourage forwards, backwards and sideways movements, but the pelvis to rotate too - which is so important for the spine’s stability.

Two separately moveable swing plates, just like two thighs, lie at the core of the 3D synchronous adjustment technology. Minimal shifts in weight are already translated into movement. The position of the pivotal points and way they work are exactly like knee and hip joints. As a result, the body maintains its centre of gravity – no matter what posture it adopts or the way it moves.

Features:

• Trimension, synchronous, three-dimensional kinematics that encourage three-dimensional dynamic sitting.
• The synchro tension control for people weighing between 45-120kg.
• Height adjustable backrest
