Build Your Custom Chair

Seating designed and constructed to ground the user and the chair, safely controlling electrostatic discharge and tested to meet ANSI/ESD STM 12.1

Upholstered seat with high-resilience foam cushioning and internal seat board bumperguard; 16" diameter, 3.5" thick.

All chair components treated to assure grounding through the chair to ESD flooring or mat. This includes the use of conductive casters or glides, metal bases, ground control lead to assure thorough static drain if casters become insulated by dirt or dust, ESD upholstery materials, and metal-to-metal contact throughout the chair for all metal parts.

Medium, five-legged, solid cast aluminum base with caster-to-caster diameter of 25.6" and maximum width of 24.4". T-cross-section legs ensure cleanability, and endure test loads of 1.5-2x BIFMA strength requirements. Features standard 50mm tapered hub (1° 26' 16" (Morse) taper) with gauge line elevation of 113mm from the caster insert plane. The base is cast out of UNI EN 46100 aluminum with a robotically polished top surface to ensure quality and consistency.

For medium height work surfaces such as workbenches 31" to 38" high. Provides a range of 19" - 26".

Two inches in height, with dual soft-wheels. Casters resist movement when the seat is unoccupied. Plastic collar around caster stem to match base. Black tread indicates an ESD caster.

Task control with Soft Touch pneumatic seat height adjustment.

22" dia. aluminum foot ring includes easy-to-operate hub – push down top of center bushing, adjust to desired height, and release to lock the foot ring into place. 22" flattened tubing ring is attached to the cast aluminum spokes with stainless steel screws, which utilize a T-cross section to provide a clean, cohesive look for models with aluminum (A / P25), reinforced composite (R / GR) or wide aluminum (W / P28) bases. Recommended for models with seat heights greater than 22 inches.
