The A-dec 500 dentists stool offer a dynamic seating system that conforms and moves with the body. With years of research behind it, the innovative A-dec 500 stool is strategically engineered to help you feel your best, so you can perform your best.

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 the spine and provides better circulation for your feet and extremities. The A-dec 500 stool’s easy-to-follow numbered paddles encourage customised adjustments—especially important if there are multiple users.

A-dec are a world leader of dental treatments units and dental equipment.

Tilt Seat

Distributes weight from seat to feet allowing proper circulation.

Contoured Backrest

Cradles the spine, while encouraging blood flow. Contoured backrest is standard on the A-dec 500 doctor’s stool and optional on the A-dec 500 assistant’s stool.

Whisper Quiet Casters

New design provides smooth, ultra-quiet movement on both carpet and hard flooring.

Adjustment Controls

Labeled paddles are easy to access for quick adjustments and easy cleaning.

Backrest Height Control
