A chair including a seat support, a seat movably supported on the seat support for movement between a raised position permitting sliding depth adjustment of the seat and a lowered position preventing adjustment, and a detent device for securely holding the seat in the raised position while the seat is being slidable adjusted. A rack is formed integrally on or attached to the bottom of the seat shell. The detent device includes a seat support bracket attached to a top of a chair control, and a pair of moldings attached to opposite sides of the bracket. The moldings each include upwardly facing teeth for selectively engaging the racks to hold the seat in a selected, depth adjusted position. A resilient finger on each molding is adapted to engage a ridge on the seat shell for selectively holding the seat in either a raised position or in a lowered position. The seat shell engages mating structure on the seat support bracket to permit guided sliding of the seat when in the raised position for depth adjustment, and to prevent cocking and twisting of the seat shell during the depth adjustment.
