Four ergonomic supports work together in this adjustable gaming chair to help you stay comfortable while you game or work, including a 20.5 x 30.5 in high backrest, headrest, waist pillow, and thick sponge seat cushion. The seat height adjusts from 17-20 in and the backrest reclines from 90° to 155° so you can sit upright or lean back to rest. A retractable footrest with pull belt lets you stretch your legs, while 360-degree swivel and five rolling casters help you move easily. PVC and PU leather surfaces are waterproof and simple to wipe clean, and the heavy-duty structure supports up to 330 lbs.
