Abstract: There is described a step comprising a single foot secured to the floor for supporting a hinge system and a board onto which a user can step. The foot has an inclination ? with respect to the floor, wherein the inclination ? is fixed and lies between 45° and 80°. The hinge system installed on the foot provides a hinge with respect to the foot. The board extending in a plane is fixedly secured to the hinge system and hinges between a stowed position and a working position. The board is substantially horizontal when in the working position, and inclined at the inclination ? when in the stowed position. The board is adjacent to surfaces of the foot and of the cap onto the hinge system, and does not define any acute angle with these adjacent surfaces. The board has a recess that, upon hinging, always conforms to the cap.

Abstract: A booster seat assembly for securing a child in a barber chair includes a barber chair that has a seat and a backrest.
