Product description
The Boss Diamond Task Chair (B9091-CS) is a mid-back ergonomic task chair built for productivity and all-day comfort. Its contoured back promotes proper posture that helps prevent back strain, while extra large seat and back cushions deliver comfort across a full workday. The chair is upholstered in black antimicrobial vinyl, a surface that resists microbial growth and wipes clean — making it a practical choice for healthcare environments and other settings where hygiene matters.
Functional adjustments include adjustable arms, pneumatic gas lift seat-height adjustment, and adjustable back height and depth, so the chair can be dialed in to the individual user. The chair rides on a 25-inch nylon base with dual-wheel 2-inch nylon casters and supports a weight capacity of 275 lb.
The B9091-CS carries MAS Green certification and meets CA TB117-2013, and it is available in four colors to match an existing color scheme.
