A slide system has a base inflatable structure capable of sustaining an air pressure, and a slide surface supported by the base inflatable structure. A lower slide flap forms a bottom end of the slide surface, and a lower slide support of the base inflatable structure supports the lower slide flap. A bumper body receives air pressure from the base inflatable structure to inflate to form a protrusion that extends upwardly from the lower slide support when inflated. A restraint structure restrains the bumper body to a flattened configuration, but when the restraint structure is released, the bumper body inflates to form the protrusion that forms a bumper at the bottom of the slide.
