A chair (10) for use in positioning wire mesh (100) within a concrete slab including a base (12), a pillar (14) and a top portion. Positioned on the top portion are at least one pair of horizontally oriented clips (18, 20) which are caused to engage the wires of the wire mesh (100) by turning the chair (10) while holding its top portion against the wire mesh (100). |
