The Saturn Office Chair features an upholstered backrest over a unique hexagonal backrest made from thermoplastic elastomers that are designed to flex and move with the user to provide firm, continuous support. The fully upholstered neutral gray seat and back offers a slightly more conservative aesthetic that blends well into almost any contemporary decor. Additional features include synchro-tilt control that reclines the back at a higher ration than the seat for proper back alignment, height and width-adjustable arms for shoulder and upper body support, a waterfall seat edge that promotes better leg circulation, a 360-degree swivel and pneumatic height adjustable seat, tilt-tension controls the rate and ease of reclining, a tilt lock mechanism and a seat glide that accommodates users of all leg lengths and slides forward when the back flexes to maintain a natural posture. This modern office chair's frame and five star base are made from durable plastic and supports up to 300 lbs. Meets or exceeds ANSI/BIFMA and ITSA performance standards.
