Non-Stop Heavy Duty is a powerful combination of durability and comfort for task- intensive environments. Non-Stop differs from the typical chair construction in that all mounting points – seat to mech, arms to seat and J-bar to back – are re-enforced with heavy gauge steel mounting brackets. These solid steel fasteners are second to none for reliability and ergonomic comfort in high-intensity environments where chairs perform all day, every day and support a wide range of users. Non-Stop is available in two sizes with ve arm and multiple control options. These heavy duty chairs are rated to accommodate users up to 350 or 500 pounds and easily handle the demands of 24-hour environments.
