Some chairs are made for optimum back support, and other high-end office chairs are ergonomically designed to support prolonged seating. 

Usually, a desk chair should be at a height just below the length of a user’s knee cap when standing.  This height allows your feet to rest flat on the floor and your knees to ergonomically bend at a 90 degrees angle. 

Desk chairs are recommended to be in the height of around 16 to 20 inches tall and somewhat 18 inches deep. If backs are available on the seat, they are typically about 14 inches high. If an armrest is available, it should carry the arms without raising the shoulders.
