BIKER DRUM SEAT STYLE WITH ADJUSTABLE BACKREST: The removable backrest is comfortable with an adjustable height feature on the padded back support to provide critical lower back support. This will allow the tailbone (coccyx) to rest naturally versus being compressed against the seat without a backrest. This will also provide a more natural movement of the spine and shoulders while seated, keeping you relaxed and comfortable when performing with lessened stress on your posture.
