How to assemble and maintain a piano bench

1) Washers: These flat metal rings protect the legs which are made of wood.

2) Split washers: These washers are split, with one end slightly bent outward to bite in, secure, and prevent loosening. Split washers act like springs under compression, to provide extra holding force, and to decrease frictional resistance during assembly and disassembly.

3) Nuts: Screw-in tight to support the legs.

4) Screw all four legs of the bench to 90% tightness,  place the bench on the floor, seat down. Press down on the bench to level the legs and tighten. Benches with storage are normally tightened from the inside, so follow the above steps until tightening. Lay the bench on its side (long edge) and tighten while securing the legs with the other hand.

5) Do not adjust the height while you are sitting on an adjustable bench. Stand up or adjust from the side so no weight is pressing down.

6) Tighten the nuts occasionally to secure the bench. Swinging on the bench will damage the wooden legs. Moving the bench may loosen the nut, and if you continue using the bench with loose legs it is only a matter of time before the wood deteriorates and the bench is unusable.
