The mechanism determines how your chair moves and what adjustment capabilities it will have. For maximum adjustability, we recommend the Multi-function tilt.

Knee Tilt 2:1

The Knee Tilt mechanism tilts from just under your knees and offers a more executive feel to the tilt. Back and seat tilt in a 2:1 ratio which means that for every 2 degrees your chair tilts backwards, your seat front rises 1 degree. This mechanism does not include a forward tilt lockout.


The Multi-Tilt mechanism tilts from the center of the seat for a more traditional feel. Back angle can be adjusted independent of seat angle. Seat and back tilt in unison. This mechanism includes a forward tilt lockout.
