Abstract
Abstract A chair structure comprising a one-piece, loop-shaped tubular frame having a pair of leg structures depending from and supporting the frame. A mesh body support member including a back and seat portion having a plurality of relatively closely interwoven metallic strands, with the strand ends at side and end marginal portions securely connected to the frame. The support member is formed of resiliently flexible mesh material whereby the same elastically yields to the weight of a user, such that the chair back and seat has a small curvature and an attractive appearance and yields tending to conform comfortably to the seated shape of the user.
