Adjustable Two-Step Base
Dual-height stool base provides two different levels of stool usage. The upper level can be used as a footrest when seated, while the lower level is great for stepping up into the chair or even standing on. The steps are height adjustable, and the base includes our standard 7-legs and casters

You may not notice it in the first 10 minutes, but you may after the first shift. You will certainly notice it after weeks, months, and years of prolonged seating in a Concept Seating chair. You’ll just feel better. You just might not know why. The chair you have just been sitting in with its Ergo Air Suspension System (EAS2) has kept the blood and oxygen flowing through your body, especially through the lower extremities improving blood flow and increasing oxygen levels to tissues.
Two-point stem, shock absorber, and special bore construction provide an extremely smooth and quiet swivel and roll not found in standard casters. Once the chair is sat in, the brake is released and allows the chair to roll freely. This is important for large people that need to put weight on the chair's arms to be able to sit. Spring shock absorber prolongs the life of the caster as well as the chair. Closed Construction reduces the amount of dirt and hair that can get into the caster, prolonging its life.
Seat Height & Depth Adjustments
Our goal is to provide proper ergonomic support for 4% female size (approximately 5’ 2”) to the 96% male size (approximately 6’ 6”). Height and depth adjustments are at your fingertips.
Easily adjust the width of the armrests to accommodate a larger person or a person with a duty belt just by sliding out the arms. Adjustment is made by loosening the thumb screw and adjusting to the desired width. Adjustable to 2.5” on both sides.
5-Position Tilt Lock
Recline to one of five desired positions and keep it there with the push of a button.
2:1 Recline Ratio
The 2:1 Syncro tilt keeps your knees and legs in an ergonomically correct position while allowing you to comfortably recline. For every 2 degrees of back recline, the seat reclines 1 degree, maintaining ergonomic comfort.
