A Floorless Coaster, commonly known as a Floorless Roller Coaster, is a type of steel roller coaster manufactured by Bolliger & Mabillard where riders sit with no floor underneath them, allowing their feet to swing freely just above the track. Development of the Floorless Coaster model began between 1995 and 1996 with Medusa at Six Flags Great Adventure opening on April 2, 1999, making it the world's first Floorless Roller Coaster. Floorless Roller Coasters also tend to have 3 to 7 inversions incorporated in the layout of the coaster.

A steel roller coaster is a roller coaster that is defined by having a track made of steel. Steel coasters have earned immense popularity in the past 50 years throughout the world. Incorporating tubular steel track and polyurethane-coated wheels, the steel roller coasters can provide a taller, smoother, and faster ride with more inversions than a traditional wooden roller coaster.
