Abstract: An apparatus comprises a stowable step including a mounting plate, a platform for supporting a load when the platform is in a deployed position in which the platform is perpendicular to the mounting plate, and a folding assembly that enables the platform to transition between the deployed position and a stowed position in which the platform is parallel to the mounting plate. The stowable step also includes a pedal assembly that enables a transition between the deployed position and the stowed position to be completed by a person's foot. When the pedal assembly is pressed, while the stowable step is in the deployed position, the folding assembly transitions out of the deployed position and when the pedal assembly is pressed, while the stowable step is in the stowed position, the folding assembly transitions out of the stowed position.
