Office chairs provide many different features for the user to consider when finding the perfect chair to fit the ergonomic needs. The descriptions of the features shown are meant to be general explanations. The following explanation of the different features available will help you choose the office chair that's right for you.

The pneumatic seat height adjustment feature regulates the height of the chair relative to the floor with a quick and easy adjustment. The back height adjustment feature is a simple lift motion to the back height that positions lumbar support within the fixed range to alleviate back stress. The seat depth adjustment feature positions the chair back relative to the chair seat, reducing pressure on the buttocks and thighs for both shorter users and taller users. The seat glide mechanism feature allows the seat cushion to travel forward and back, then locks into the desired position. The 360 degree swivel feature allows the office chair to rotate a full 360 degrees in all directions for ease of motion. Standard on every executive and task chair. The tilt feature is a pivot point that is located directly above the center of the chair base for a seat and seat back allowing movement in the forward and back directions creating a rocking motion. The mid-range knee tilt feature is a pivot point that is located slightly ahead of the center of the chair base, allowing the user to recline at a slightly more relaxed angle than the conventional center seat tilt. The knee tilt feature has a pivot point located near the front edge of the office chair. Allowing the user to keep their feet flat on the floor sitting in the upright position and when the chair reclines. The synchronized knee tilt feature allows the back to recline at a 2-to-1 ratio to the seats angle. The pivot point is located near the front edge of the office chair. The dual action tilt feature allows the back to recline at a 2-to-1 ratio to the seats angle. This allows the user the ability to recline the seat while keeping the seat relatively level to the floor. The tilt tension feature controls the rate and ease with which the chair reclines to the users different weight and strengths. The tilt lock feature locks out the tilt function when chair is in the upright seated position. The posture lock feature allows the seat's back angle to adjust independently of the seat, and can be locked in an infinite number of positions within a fixed range. The multi-task control feature adjusts the seat and back angles with a single lever (infinite locking within a fixed range), reducing fatigue in back and thighs. The asynchronous control feature uses three levers to modify; the angle of the back relative to the seat, the chair's tilt (free float or infinite locking within a fixed range), and the chairs forward tilt (for keyboard intensive applications). The dual-clutch posture control feature adjusts the seat and back angles independently with two levers for infinite locking within a fixed range. The variable synchro-tilt feature allows the back to recline at a 2-to-1 ratio to the seat. The chair is able to tilt freely, or lock in five positions "forward angle" control provides an extra 6 degrees in the range of motion. The inverse synchro-tilt feature has an automatic tension control operation for better circulation. "Zero tilt" seat front helps to keep the feet on the floor when reclining. The tilt lever controls the range of motion. The independent seat and back feature allows the seat and back to flex independently for an automatic comfort. The integral lumbar support feature allows the chair to easily adjust to enhance comfort (2.5" adjustment range). The hip pivot motion feature allows the seat to remain stationary while the back of the seat adapts to the users body movement.

The actual functions of the features may vary slightly among the many different office chair manufacturers.
