Cramer Helix Lab Chair, Cleanroom ISO Class 4

Cramer Helix Cleanroom Lab Chair, ISO Class 4

Helix is built around Cramer's Frameless Back, which flexes with the user instead of relying on knobs and levers, so the only adjustment is one-touch seat height. The seamless i+ polyurethane seat and back resist harsh cleaners and lab chemicals and meet BIFMA HCF 8.1 cleanability guidelines, and the chair is rated for ISO Class 4 (Fed Std 209e Class 10) cleanrooms. A good fit for shared lab and healthcare stations where several people use the same chair.

This chair is built-to-order to your exact specifications and usually ships within 5 business days. Delivery can typically be expected in 1-3 weeks from order date. Products may be returned only with manufacturer (Cramer) approval and will be subject to their restocking charge. Cramer reserves the right to deny credit for any damages.

Compare: for ISO Class 3, the Citrus or Loop; for heavy-duty, all-day sitting in ISO 5 areas, the Fusion. All options: cleanroom chairs.
