No matter whether you play guitar, keyboard or another
  instrument, this redesigned stool lends the right support for
  your back every time you play. The ergonomically shaped seat will
  perceptibly relieve pressure on your back and prevent premature
  tiredness. Moreover, the seat, which is covered with fabric, can
  be freely adjusted to any angle. The height can be adjusted from
  600 to 900 mm to suit every individual. The practical and
  beneficial foot rest can also be height adjusted. The robust
  construction of the legs and the integrated foot end caps ensure
  the stool is sturdy and safe. The stool can be folded flat for
  transport.
