The term 'BENCH Board' is a combination of two words, 'BENCH' and 'SLAT'. BENCH is a long seat, typically made of wood, that is used for seating multiple people. SLAT is a thin, narrow strip of material, usually wood or metal, used to form a lattice or grille. Together, the two words form a type of board used to make benches, which consists of a series of slats arranged in a row. This type of board is often used in outdoor furniture, such as park benches, and can also be used to make indoor furniture, such as dining room tables.
