Five-position adjustable armrests and a wide 21 x 21 in seat with thick cushioning provide supportive seating for big and tall users. The backrest adjusts through three positions from a 90° upright angle to a 120° recline, so you can move from focused tasks to reading or TV. A retractable 12.5-in footrest extends to support your legs when you lean back. The height-adjustable swivel seat and 5-claw metal base with smooth casters are built to support up to 500 lbs.
