The chair includes a movement mechanismthat causes an upper base unit () to swing in a direction of 360 degrees with respect to a lower base unit (), and a seatattached to the upper base unit (). The chair further includes a damper mechanism (DM) that may operate by following a movement in a direction of 360 degrees, as a mechanism separate from the movement mechanism (), at a position connecting the upper base unit () and the lower base unit ().
