What is seat depth adjustment on an executive chair?

Seat depth adjustment (also called seat slide) allows you to move the seat pan forward or backward relative to the backrest, changing the effective depth of the seat. This ensures your back contacts the lumbar support while 2"–3" of clearance remains between the seat front and the back of your knees. Without this feature, shorter users may find the seat too deep, causing them to lean forward and lose back support.
