BigBoss – Heavy-Duty Ergonomic Seating up to 550 lbs

The BigBoss is Sitmatic's flagship heavy-duty chair, designed for users who require a wider seat base, reinforced frame, and higher weight capacity. Rated at 550 lbs for 24/7 use, the BigBoss maintains the same ergonomic adjustability as standard Sitmatic models — no compromises are made in fit or function.

Built for Demanding Environments

An extra-wide seat with a seat slider allows users to customize depth precisely. The synchronized rocking control enables healthy movement without sacrificing lumbar support. An adjustable headrest and high back ensure full-length spinal alignment for extended shifts.

Features and Adjustments

The BigBoss is available in desk chair and drafting stool configurations, making it ideal for workstations at standard and standing-height desks. Sitmatic's no weight limit philosophy ensures every individual gets a properly fitted ergonomic solution.
