An ironing board with variable configuration between a shipping configuration with small overall dimensions and an operative configuration in which it is designed to be stably placed on a stationary support structure, for example a platform or a floor, the board comprising: - a body comprising a first element for resting on the stationary support structure defining a first plane ( π1); - at least one second element for resting on the stationary support structure defining a second plane ( π2); - an ironing plane defining a third plane ( π3); wherein said at least one second resting element and said body are mutually movable between a first operative position which they take when the ironing board is in the operative configuration in which said at least one second resting element cooperates with the first resting element to define a unitary base for the stable support of the ironing board to the stationary support structure having said first and second planes ( π1, π2) substantially parallel or coincident and a first inoperative position which they take when the ironing board is in the shipping configuration in which said first and second planes ( π1, π2) are substantially perpendicular; wherein said ironing plane and said body are mutually movable between a second operative position which they take when the ironing board is in the operative configuration in which said first and/or second plane ( π1, π2) and said third plane ( π3) are substantially parallel and mutually spaced and a second inoperative position which they take when the ironing board is in the shipping configuration in which said second and third plane ( π2, π3) are substantially parallel or coincident with respect to each other and they are substantially perpendicular to said first plane ( π 1); wherein the ironing board is of professional or semi-professional kind; and wherein said body is substantially box-shaped. - a body comprising a first element for resting on the stationary support structure defining a first plane ( π1); - at least one second element for resting on the stationary support structure defining a second plane ( π2); - an ironing plane defining a third plane ( π3); wherein said at least one second resting element and said body are mutually movable between a first operative position which they take when the ironing board is in the operative configuration in which said at least one second resting element cooperates with the first resting element to define a unitary base for the stable support of the ironing board to the stationary support structure having said first and second planes ( π1, π2) substantially parallel or coincident and a first inoperative position which they take when the ironing board is in the shipping configuration in which said first and second planes ( π1, π2) are substantially perpendicular; wherein said ironing plane and said body are mutually movable between a second operative position which they take when the ironing board is in the operative configuration in which said first and/or second plane ( π1, π2) and said third plane ( π3) are substantially parallel and mutually spaced and a second inoperative position which they take when the ironing board is in the shipping configuration in which said second and third plane ( π2, π3) are substantially parallel or coincident with respect to each other and they are substantially perpendicular to said first plane ( π 1); wherein the ironing board is of professional or semi-professional kind; and wherein said body is substantially box-shaped.
