National Public Seating’s 8200 Series Melody Music Chair is a great choice for band performances or any activity that requires your back to be in an upright position. This durable polypropylene chair has a 97-degree seat-to-back angle that allows for maximum breathing capacity. The extended back is contoured for extra comfort. Four stack bumpers protect the 16-gauge frame from scratches when stacked. Opt for a tablet arm that flips up and behind the chair when not in use.
