The present application relates to a garment steamer device comprising a base, a steam generator, a garment steamer head connected to the steam generator by a steam hose and a support structure extending upwardly from the base. The device includes an ironing board attached to a support member extending below the ironing board. The support member is connected to the support structure such that the ironing board is pivotable relative to the support structure and can be fixed in a position in which the ironing board is inclined at an angle between horizontal and vertical. The device also includes a garment hanger cooperating with the ironing board. The garment hanger is retractable and has a retracted position in which the garment hanger does not extend beyond a distal end of the ironing board, and an extended position in which the garment hanger extends beyond the distal end of the ironing board. The garment steamer of the invention allows improving steaming user experience thanks to a smart combination of an inclinable board with an extensible/retractable garment hanger.
