ERGObone harness set includes black harness and the clear chest piece. Please note, this is an additional set for the basic chair set so this does not include the attaching clamp, and the adustable spring mechanism. With this pack you can upgrade the chair set to full set.

The ERGObone also promotes better management of breath.

Play sitting, play standing - either way it is always comfortable because your arms, hands and back are relaxed as the weight of the horn is transmitted to the chair or through the harness to your shoulders like a back pack!
