Chair Mechanisms - Pneumatic Seat Height Adjustment

Pneumatic Height Adjustment Chair

Take your chair to greater - or smaller - heights. This pneumatic adjustment feature allows you to change the height of the seat based on your height, so your feet stay grounded, without any gaps between you and the floor. Pneumatic height adjustment mechanisms work by using pressurized air to lift and lower the seat. We selected a couple of our favorite chairs with this feature below.

This mechanism guide is designed to provide information about chair functions and features so you can make an informed decision based on your needs, preferences and styles. For more information on other chair mechanisms, check out our chair buying guide.
