Dynamic support
Three layers of flexible seating conform to your every shift and move. Four unique performance zones allow good blood flow to the legs, while setting up the lower lumbar for a proper, healthy torso posture all day long.

Healthy seated posture
Our dynamic seating system helps your spine maintain a healthy S-shape. This ergonomic seated position lets you enjoy both comfort and improved performance.

Easy adjustment
Correct posture reduces stress on joints and spine and provides better circulation for your feet and extremities. The A-dec 500 stool’s easy-to-follow numbered paddles encourage customized adjustments—especially important if there are multiple users.
