BioFit BT-Series Ergonomic Static Control Chair

The Bridgeport BT-Series Ergonomic Static Control Chair is designed with ergonomics in mind for long days and features durability for long-term performance. Every part of a BioFit static control chair is grounded to the base, and every chair includes a drag chain and conductive glides or casters, since dirt acts as an insulator that can disrupt continuity.

A spring-loaded contact ball bearing assembly within the pneumatic seat-height adjustment mechanism is unique to BioFit. This ball bearing rides on the pneumatic mechanism's inner cylinder, ensuring continuity from the top of the backrest and seat, through the pneumatic cylinder, to the base.

The backrest measures 14-1/2 inches wide by 9-1/2 inches high with lumbar support and a plastic protective panel. The seat has a concave design, 18-1/2 inches wide by 16-1/2 inches deep by 3 inches thick, with an internal seat board bumper guard. Controls come standard with Task Control Soft Touch pneumatic seat-height adjustment, a fixed rearward seat tilt of 3-1/2 degrees, and backrest tilt and height adjustment. Casters and glides include dual-wheel, non-marring polyurethane casters that resist rolling when unoccupied, or optional 2-inch-high polyamide glides. Metal parts are chrome-plated, and the chair supports up to 350 pounds.

To find your ideal seat height, subtract 12 inches from your work surface height. Use that number as the mid-point of the seat height adjustment range you choose. This formula fits most workers, and BioFit's range of adjustment options accommodates the rest.

Selection Guide:

♦ S-Base, 23" diameter tubular steel base with a 21" diameter affixed footring: available in Low (18" to 22"), Medium (21" to 28"), or High (25" to 32") seat height
♦ A-Base, 25.6" diameter cast aluminum base: available in Low (17" to 22"), Medium (19" to 26"), or High (22" to 32") seat height
♦ W-Base, 28.7" diameter wide aluminum base: available in Low (17" to 22"), Medium (19" to 26"), or High (22" to 32") seat height

Selecting the Right Model:

♦ Work surface height: subtract 12 inches from your work surface height to find your ideal mid-point seat height, then choose the Low, Medium, or High range that includes it.
♦ Base style, the S-Base with footring suits users who like a place to rest their feet, while the A-Base and W-Base offer wider stability without a footring.
♦ Grounding path: both conductive glides and casters provide a reliable grounding path, so the choice comes down to mobility preference.

Where Commonly Used:

♦ Electronics Assembly and Testing: The grounded, conductive construction protects sensitive components during handling and testing.
♦ Semiconductor Manufacturing, the drag chain, and conductive base support ESD program requirements.
♦ Cleanrooms and Controlled Environments: The chrome-plated construction supports hygiene requirements.
♦ Multi-Shift ESD Facilities: The range of seat-height adjustments accommodates workers across shifts.
