Piano stool

A piano stool, also referred to as a piano bench or piano chair (depending on its style) is a seat especially designed for use at the piano, though it has been largely unchanged since its creation and has been demonstrated (in an isolated scientific experiment conducted by physical therapist scientists) to increase the acquisition of musculoskeletal disorders in pianists.

Its height is sometimes adjustable to accommodate players of various sizes. It is often padded, either with an integrated foam-filled cover or a purpose-made detachable cushion. In its bench form, it sometimes has a hidden compartment for storing music sheets and other supplies.
