摘要： A nesting chair includes a base having a transverse member. A backrest and seat are interconnected with the base. A seat rotation mechanism is configured to allow the seat to rotate from an initial seating position to an upwardly rotated nesting position. The seat rotation includes a first bearing area defined by an underside of the seat, and a second bearing area defined by a separate bearing member. The first and second bearing areas are located on opposite sides of the transverse member. A retainer arrangement is used to secure the bearing member to the seat with the transverse member therebetween. The seat is rotatable about the transverse member from the initial seating position to the upwardly rotated nesting position to enable the nesting chair to be nested with a plurality of like chairs. The transverse member is provided with a stop engageable with the seat for maintaining the seat in the seating position.
