context_page_description: A Floorless 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 Coaster. Floorless Coasters also tend to have 3 to 7 inversions incorporated in the layout of the coaster.
  Recently, Bolliger & Mabillard have used floorless trains on their Dive Coasters, such as Griffon and SheiKra. Though they contain floorless trains, the coasters are still not considered Floorless Coasters as B&M classifies them as another model. Maurer Söhne has designed their own version of the Floorless Coaster, a variant of their X-Car called X-Car Floorless, but currently do not have any installations.
context_section_description: Bolliger & Mabillard has built thirteen Floorless Coasters from the ground up, with three additional that were converted from stand-up roller coasters. The roller coasters are listed in order of opening dates.
  Note: Although some Dive Coasters (such as SheiKra, Griffon, Valravn and Yukon Striker) feature floorless trains, they are not considered Floorless Coasters.
