Abstract
A concrete chair elevates rebar above an underlying surface. The chair includes a rectilinear rim having a length, width and height of different distance. The rim may be oriented so each side abuts the underlying surface so rebar can be supported at three different heights above the underlying surface. In a foundation pour, the chair supports rebar at three different elevations. In a tilt wall pour, the chair supports rebar at three different elevations and produces a mark on the cured wall of considerably reduced extent.
