The present application relates to a garment treatment device comprising a base, a support structure extending upwardly from the base, and an ironing board connected to the support structure. The ironing board is pivotable relative to the support structure and positionable into a first operative position in which the ironing board is horizontal, and a second operative position in which the ironing board is vertical. The ironing board comprises a first section and a second section hingedly coupled together and pivotable relative to each other between an operative position in which they extend co-planar to each other and a storage position in which they are pivoted away from a co-planar orientation. The first and second ironing board sections (4a,4b) and the hinge mechanism (18) are configured such that the first and second ironing board sections (4a,4b) pivot away from each other from said operative position towards said storage position. The garment treatment device thereby advantageously enables garment it treatment in a variety of orientations, such as flat ironing or vertical steaming, with the ironing board providing garment support in all operative positions. Also, the garment treatment device advantageously allows for a compact configuration in the storage position for efficiency of storage space.
