PROBLEM TO BE SOLVED: To prevent a net member from being bent in a seat structure for a chair wherein the net member is extended on the upper surface of a seat frame. SOLUTION: The seat frame 1 includes a hard part 4 in the outer peripheral part, and an elastically deformable extending piece 5 inclining inward and downward is arranged on the upper surface of the hard part. The circumferential part of the net member 2 is extended over a part from the upper surface of the extending piece 5 to that of the hard part 4 in the seat frame 1. When a user is not seated, the circumferential part of the net member 2 is separated from the upper surface of the extending piece 5. When the user is seated, the circumferential part abuts on the upper surface of the extending piece 5. COPYRIGHT: (C)2004,JPO
