Modular slide apparatus and system

A modular slide assembly for use on a staircase, the modular slide assembly comprising:

• first and second slide modules, each comprising:
• an entry section comprising:
• an entry surface defining a seat;
• and
• a gripping surface substantially opposite the entry surface, the gripping surface being configured to interface with a tread of a stair of the staircase;
• a ramp section comprising:
• an elongated surface extending from the entry surface of the entry section at a downward angle towards a terminal end of the ramp section wherein the elongated surface comprises a first planar surface;
• and
• an underside configured to rest upon one or more stair nosings of the staircase;
• and
• left and right sidewalls spanning opposing lateral sides of both the ramp section and the entry section, the left and right sidewalls each comprising an upper edge having a smooth upper surface defining a handrail, wherein the left sidewall comprises a second planar surface extending from the a lower edge proximal the elongated surface to the upper edge, and wherein the upper edge extends further than the lower edge when measured along a length of the ramp section,
• wherein the underside of the second slide module is sized and shaped to integrate with the entry surface and the elongated surface of the first slide module to form a modular slide having an extended ramp section.
