Abstract
The chair, particularly an office chair, has a backrest articulated to a seat support by way of a rest support. A seat surface is movable synchronously with the backrest. A front region of the seat surface is connected to the seat support via a sliding guide and a rear region is connected to the seat support via a seat link. A distance from an upper pivot point, which connects the seat link to the seat surface, to the backrest is shorter than the distance from a lower pivot point, which connects the seat link to the seat support, to the backrest. The movements of the backrest and of the seat surface are synchronized by a sliding guide provided between the seat link and the rest support.
