In the deployed configuration of the chair 100, the connecting member 112 extends at an upward angle from the rear leg frame 108 relative to horizontal. The second holder(s) 113 is attached rearwardly to the second chair connecting member 112. The overall length/width of the holder 113 is dimensioned greater than the length/width of the holders 111, allowing for a single elongated holder 113 to be used. The use of a single holder 113 results in a connecting member 112 that is dimensioned less in width than the connecting member 110. When viewed from the rear of the chair 100, the holder 113 is centrally aligned between and below the holders 111, ensuring a secure connection is made when coupling to another chair 100. In some embodiments, the holder 113 can be secured to the connecting member 112 using fasteners (not shown) engaged with a threaded opening formed in the connecting member 112 to allow for replacement of the holder 113 if damage occurs. In some embodiments, the connecting member 112 can include a slotted opening and the rear of each holder 113 can include a flange such that insertion of the flange and rotation of the holder 113 locks the holder 113 relative to the connecting member 112 without the use of fasteners. In some embodiments, the rear of the holder 113 can include tabs that snap into complementary openings in the connecting member 112 to secure the holder 113 to the connecting member 112. The holder 113 is fixed in position (e.g., cannot rotate relative to the connecting member 112) and is oriented to face away from the connecting member 108c.
(21) The second holder(s) 113 is configured to connect to a corresponding base connecting member 108c of a rear leg frame 108 of another folding chair 100b as illustrated in
