Folding seat
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.
Folding seats may also be found in stadiums, arenas, theaters and auditoriums where they facilitate entry and exit.
