The Empire Piano Teacher Piano Bench features two separate adjustable seats, allowing the instructor and student to sit at different heights. This is a great bench for piano teachers, or for playing duet performances. The two seats adjust in height from from 18" to 22", and each seat measures 21.5" x 15" (making the total bench size 43" x 15"). The duet bench comes in an ebony (black) finish, and has finished wooden adjustment knobs.
