Desk Height Type J, Model No. 2802-74
Biofit warranty Warranty
Certificate
  • Certified by an independent laboratory to meet requirements of Fed. Std. 209E for Class 100 environment
  • Clean static-dissipative vinyl upholstery features a surface resistivity of 5.3 x 106 ohms/square
  • Ergonomic design includes "Soft Touch" pneumatic height adjustment
  • Chrome plated base and footrings ensure nonshedding surface
  • All models include conductive casters for static-safe rolling on hard surfaces

These chairs combine superb cleanliness with static-control features. All metal frame and components are carefully designed for complete static drainage and nonshedding, cleanroom-compatible performance. They feature conductive casters to ensure charge dissipation. All exposed metal surfaces are chrome plated. The static-dissipative vinyl used in their construction is layered with colored vinyl outside and carbon underneath to ensure excellent static-dissipative characteristics (see specifications below for performance test data).

This design minimizes the possibility of particle generation during everyday use. Other construction features ensure a long, trouble-free service life. Seats and backrests include internal bumper guards to enhance appearance and protect the vinyl from abrasions that occur when the chair is bumped into desks and benches. Standard backrests help eliminate fatigue and back stress; the larger ergonomic backrests feature additional internal support that enhances comfort and protects against fabric splitting. The "Soft Touch" pneumatic lift takes the contortions out of height adjustment—a simple press of a lever raises or lowers the seat to a comfortable height.
