The GTFORCE Pro ST Gaming Chair has been ergonomically designed for comfort with foam padding and a supportive, detachable back and neck pillow. Adjust the height by operating the high-quality gas pump lift mechanism. Hit the side button to recline (up to 170 degrees) and, once you have found your ideal position, simply adjust the armrests to suit. Suitable for under desk use, each armrest can go up, down, left or right. Mounted on a strong metal base with caster wheels, this sporty gaming chair will simply roll into position.
