Misericord
（重定向自Misericorde）
A misericord (sometimes named mercy seat, like the Biblical object) is a small wooden shelf on the underside of a folding seat in a church, installed to provide a degree of comfort for a person who has to stand during long periods of prayer. The small shelves were available for use at times when the folding chair was required to be stored folded up, and the person expected to be in an upright position.
