Abstract: A net fixing structure of a chair, which comprises a frame, a net, and clamping fixtures, is provided. The frame has an embedded channel. A positioning strip is disposed on the periphery of the net. An antiskid layer is disposed on the outside of the positioning strip. The clamping fixtures correspondingly clamp the antiskid layer. Thereby, when the net can be correspondingly inserted into the frame, the positioning strip around the periphery of the net can be correspondingly intercalated into the embedded channel, so that the clamping fixtures can be engaged in the embedded channel. Moreover, the antiskid layer has antiskid effect, such that the net won't slip and fall off under stress. The net can be stably fixed on the frame above.
