Abstract: A chair supports rebar or wire mesh during a concrete pour. The chair is box shaped having grooves in the side walls of different width for supporting rebar of different diameter. Notches in the edge of the grooves on opposite sides of the chair support wire mesh of different diameter. The notches are shaped so the wire mesh is snapped into the notch. Wall like braces extend across the inside of the chair and support the grooves from the opposite wall. The larger grooves are on the short sides of the chair to raise the rebar a longer distance off the underlying surface. In a preferred embodiment, the chair provides two elevations for placement of rebar, namely 2″ and 3″ above an underlying surface. Parts of the box are cut away to promote concrete movement through the chair. Slots are provided to allow air trapped in the concrete to escape from the chair.
