Bolliger and Mabillard
Most commonly known as B and M this coaster company is based in Monthey, Switzerland. Founded in 1988 by two ex-Intamin employees Walter Bolliger and Claude Mabillard. B and M coasters are known for their smoothness and comfortable restraints. They made their first coaster in 1990 called the Iron Wolf, this coaster instantly gave B and M a large amount of publicity. In 1992 they debuted their Inverted coaster which was the first coaster capable of hanging under the tracks and completing inversions. Through the years they have made many more types of coasters all of which have been very good.
