This is a combination step ladder, clothes rack, and ironing board. A step ladder is hinged in the middle to form an inverted V, with stays to keep the two halves at a fixed angle. A clothes rack refers to a frame upon which clothes are hung after washing to easily let each garment dry. Most ironing is done on an ironing board, a small, portable, foldable table with a heat resistant top. Some commercial-grade ironing boards incorporate a heating element and a pedal-operated vacuum to pull air through the board and dry the garment.

For safety, a rigid ladder should be leaned at an angle of about fifteen degrees to the vertical. In other words, the distance from the foot of the ladder to the wall should be about one quarter of the height of the top of the ladder. At steeper angles, the ladder is at risk of toppling backwards when the climber leans away from it
