The interplay of the circular table top with the conical base gives Clay a sculptural appearance. The base, made of rigid polyurethane, is available in a matt graphite grey, glossy white and also with a dark grey lava stone finish that is applied manually using a knife. The table top comes in toughened glass, ceramic or in glass or MDF boards coated with lava stone. The lava stone version of Clay is also suitable for outdoor use.
