All Steel Frame: Ten-gauge steel maintains original tensile strength and rigidity over years of heavy-duty use; enforces perfect posture. 6-Year warranty.

Adjustable Armrests: No tools required to adjust or replace. Adjustable width and height for customized comfort, security and support.

Replaceable Covers: Fabrics can wear, but our frames are virtually indestructible. Bring back that "brand new" look in minutes, even after years on the job. In a matter of minutes, a replacement cover makes your chair new again. Or, easily remove your cover to clean or repair.

Heavy-Duty Dual Wheel Casters: We specify the toughest materials for these load-bearing stress points, and conduct exhaustive component testing prior to chair assembly.

Custom Embroidery and Smart Fabrics: Logos or artwork can be embroidered into chair back or head rest.

Infinitely Adjustable Air Lumbar: Pump it up to cushion back and maintain proper spine alignment while writing, computing, phoning and monitoring.

Waterfall Front and Knee Tilt Control: Natural curvature of frame, combined with Dymetrol Suspension, prevents compression of leg nerves and promotes optimal circulation in every sitting position. Forward pivot point for knee action eliminates any vertical knee strain while tilting, allowing freedom of movement.

Seven Leg Base: Tested to 10,000 pounds; added stability locks in center of gravity, eliminates tipping, and is easier to move than 5-legged chairs.
