A folding seat is a seat that folds away so as to occupy less space. When installed on a transit bus, it makes room for a wheelchair or two. When installed on a passenger car, it provides extra seating.
In churches, it may have a projection called a misericord, which offers some support to a person standing in front when the seat is folded.
Some folding seats in rapid transit may fold down rather than fold up.
