Technical Environments

Workers in technology facilities conduct their tasks under stringent cleanroom and ESD requirements. Whether in a testing lab at a pharmaceutical start-up or an assembly line for semiconductors, Cramer chairs and stools are uniquely suited for controlled technical environments.

Technical environments require:

Contaminant Control

Our patented seamless Rhino™Plus upholstery system is anti-microbial and anti-bacterial. We also offer textiles and vinyl with soil and stain-resistant finishes.

Cleaning Ease

Focused Postures for Long Periods

From active forward leaning to recline, Cramer seating adjusts to support the full range of seated postures. Flexible, pivoting backs provide dynamic lumbar support and healthy open angles, encouraging circulation.

Active Posture


Cramer cleanroom chairs are designed for minimal particulate contribution as certified by tests conducted in accordance with ASTM F25-68 and SAE ARP 734A. Sealed pneumatic cylinders, upholstered vinyl cover and seamless covers prevent outgassing above .5 microns. Cleanroom seating is manufactured to meet ISO 14664, Class1 (ISO 3), Class 10 (ISO 4) and Class100 (ISO 5).



Cramer ESD chairs are designed to meet the ESD Association standard test method ESD Seating (STM 12.1-1997). Each chair is assembled with ESD approved parts including chrome cylinder, polished aluminum base, conductive plastic arms and foot rings and steel parts coated with conductive tints. Dual-density conductive casters eliminate the need for cumbersome drag chains. Each chair is tested individually for compliance before leaving the factory.
