The Seat Wedge (inside) can be fastened to the seat in 3 different positions:

1. An active posture is achieved by placing the seat wedge on the seat with the high side at the back and fastening in this position.

2. Attach the seat wedge with the flat side to the rear for a more passive posture / rest position.

3. In order to shorten the seat depth or for a larger sitting angle, you can also attach the seat wedge to the rear of the seat in an upright position with the broad side at the bottom.

The two outer pads for additional protection are attached on the sides.
