Designed for PC1 and PC2 (PC = Physical Containment of micro-organisms) compliance, the Clam Round drafting chair features a tough skinned polyurethane seat-pan and backrest. The polyurethane is moulded over an internal steel frame, with an integral carry handle built into the back-rest. The quad fastened back-rest stem gives extra strength. Manufactured without adornment, and configured with sturdy components, the Clam Round drafting is a rugged, stain resistant chair, impermeable to water. With its high rise gas lift and footring, the Clam Round Drafting is suitable for bench (typically 900 mm high) use.

The adjustment mechanism has individual levers for seat height and back-rest tilt, and a knob adjustment for back-rest height. Fitted with a gas-lift dust cover – note that the cover mould shape may differ slightly from images shown. The heavy duty ‘tulip’ style footring is separately height adjustable on the chair height gas stem and a 600mm black nylon star base.

Available in either black or blue, the Clam Round lab chair may be washed with warm soapy water or a mild ethanol based cleanser.
