Abstract
A chair for supporting wire mesh while pouring concrete slabs. The chair has a generally tapered, hollow body with a receiving area for fixedly retaining the wire mesh. The receiving area includes walls extending upwardly between notches, with the walls defining passageways for guiding the mesh into the notches. Detents project inwardly from the tops of the walls to fixedly retain the mesh within the passageways. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. One or more foot members are preferably attached to the lower base portion to provide for secure support of the chair on a variety of surfaces.
