The movement principle

Why Sit-i

Shift your weight and the seat responds. Here you can see how the Top Unit and the Penthapod® make that movement possible.

Our vision of sitting

Stability at the core. Freedom of movement.

A small change in posture produces a response you can feel in the seat. You can vary your position while the base supports the chair.

01

Movement at the source

The seat moves close to the pelvis and lower back, creating subtle tilting and rotation.

02

Stability with room to move

The five-point foundation follows controlled movement and natural variation.

03

From experience to understanding

With Sit-i Pro and the Academy, what you feel can become visible, discussable, and actionable.

Movement close to the body

The chair follows. You keep moving.

The Top Unit directly beneath the saddle allows the seat to tilt and turn. The Penthapod® supports the chair through five points of contact. The seat responds to small weight shifts of the pelvis and lower back.
