Recline and tilt options vary widely by model. Many chairs offer multi-angle, lockable recline with ranges from about 90° up to as much as 155°. Typical example ranges reported include 90°–155°, 110°–125°, 100°–115°, 105°/120°/125°, and some models up to 135°.

Many models offer adjustable lumbar support and adjustable headrests. Armrests vary from simple padded or flip-up designs to multi-axis adjustments (commonly labeled 2D, 3D, or 4D) that allow height, width, depth, and pivot changes for a more customized fit.
