A chair particularly useful for an auditorium utilizes spherical bearings (22) to mount the seat bottom (18) of the chair to uprights standards. The spherical bearing (22) includes a first race portion (20) integral with the bottom of the chair and a removable cap portion (24) that is secured to the chair bottom to hold the spherical bearing. An axle (28) extends through each standard to engage the bearings to support adjacent chairs. The axles are threaded to receive a nut to secure the axles to the standards.
