A chair comprising:

• a seat;
• a backrest including a back frame and a mesh having margins, the back frame comprising a front face frame, the front face frame including an upper frame rod positioned in a forward arc for securing the mesh, the upper frame rod configured as a single strip with ends and an upper reinforcement rod positioned behind the forward arc, the upper reinforcement rod configured as a single arcuate strip having a central section and ends;
• and
• a right frame rod extending along a right side of the backrest and a left frame rod extending along a left side of the backrest;
• the front face frame including a lower frame rod configured as a single strip with ends, and a lower reinforcement rod configured as a single arcuate strip having a central section and ends,
• wherein the margins of the mesh are fixed to the front face frame so as to position the mesh to upholster the front face frame,
• wherein the ends of the upper reinforcement rod and the ends of the upper frame rod each comprise part of an upper end of the right frame rod and the left frame rod, and the upper reinforcement rod is free of direct contact with any structure other than the right frame rod and the left frame rod so that the central section of the upper reinforcement rod is spaced apart and rearward from the upper frame rod, and
• wherein the ends of the lower reinforcement rod and the ends of the lower frame rod each comprise part of a lower end of the right frame rod and the left frame rod, and the lower reinforcement rod is free of direct contact with any structure other than the right frame rod and the left frame rod so that the central section of the lower reinforcement rod is spaced apart and rearward from the lower frame rod.
