Safco’s Soft-Tough Series Chairs are durable and comfortable because they are supported by steel seat and back inserts that are covered with black molded polyurethane foam. The welded steel base keeps your chair from tipping over. Attractive black propylene covers the base. The desk-height chair adjusts in seat height and has an oversized seat and back that fit nearly any body type. Simply push a lever to adjust the seat tilt up to 10 degrees and the backrest tilt up to 22 degrees. A knob allows you to adjust the backrest height.
