The Clam Square Drafting Chair is a liquid resistant polyurethane lab chair with generous seat dimensions.

The Clam has a smooth polyurethane seat and back rest surface, impermeable to water, cleanable, with resistance to mild cleaning agents and disinfectants.

It is washable with warm soapy water or ethanol based cleansers.  PC1 compliant and PC2 complaint.

Why buy this:

In comparison with most industrial chairs, the Clam Square Drafting Chair has a larger seat and a substantial back-rest for user comfort.

Previously known as the Big Fella Drafting Chair, the seat comprises a tough polyurethane skin moulded over a robust steel and wooden frame. It features individual controls for adjustable seat height, as well as back-rest tilt and height adjustment. The Clam Square is easy to wipe clean, and has a gas lift cover to minimise dust under the seat. The drafting ring provides height-adjustable foot support.

The Clam Square Drafting Chair can be supplied with soft castors to reduce rolling on hard surfaces, hard castors for carpet floors, or glides for stability on level surfaces. A Premium drafting star base package can also be added, which includes a heavy duty alloy star base, a chrome gas lift and a heavy duty tulip foot-ring.

Who buys this:

The larger dimensions of the Clam Square Drafting Chair make it ideal for many industrial, lab, or workshop environments.
