ABSTRACT:
This device will allow the user access to a platform and also use the device as an additional step. It will be easy to move and easy to stow. Unlike a footstool it can be easily stowed under cabinets or chairs. A hole in the center section, which is the step, allows the user to easily move it from location to location. Hinges on the sides of the steps allow the step to be raised and lowered at will and a stop mechanism is provided to allow the step to be raised and stay in position.
