Balanced Back

Two complementary materials are fused together to create a back that supports you as you switch tasks and shift focus. The lower back is more structured, providing lumbar support and control, while the upper back flexes with your movements.

Active Pivot

The active pivot control delivers a smooth, effortless recline without any manual adjustments. The automatic, synchronous motion between the back and the seat dynamically responds to you, sliding the seat forward and up as you recline.

Adjust and Go

The perfect fit only requires seat height adjustment with one simple lever.


Upper and lower back can be specified seperately, in different colors.
