THE PRODUCTION

Producing the clean lines of the Polyhedrica chair involved a complex and precise production process, with 16 different angled joints in the construction of the plywood enclosure alone.  

The body of the Polyhedrica chair is built using plywood made from high quality Australian hardwood. The ply is unusual in that every layer is equal in thickness, and every veneer throughout the whole thickness is made from selected Spotted Gum (Eucalyptus henryi). This means the plywood is extremely durable and resistant to damage.

The chair is glued together by hand using concealed timber connecting pieces and the highest strength adhesives. A host of clamps and jigs was required for the assembly.  The base and back are connected using contrasting recycled Red Mahogany (Eucalyptus resinifera) machined precisely to give a slight flex in the back of the chair as you settle into it.

The base is made from polished stainless steel, with the angles carefully cut and welded to complement the lines of the body of the chair.  The base is fixed to the chair with custom designed connecting plates which allow the base to be secured with a metal thread and easily unbolted for transport.  

The plywood is finished with Osmo Polyx Oil, a natural plant oil and wax based finish which brings out the grain and depth of colour in the timber.
