Abstract: The ironing board comprises a perforated worktop (1) enclosed by a casing (2) with which it defines a chamber (3) associated to ventilation means for the steam ejected by an iron to pass therethrough. The ironing board further comprises adjustable support legs (8, 9), whose upper end portions are connected directly to the worktop (1). At least one (9) of these legs is adapted to pass in an air-tight manner through a longitudinal aperture (20) provided in the casing (2).
