Our Signature® Choral Risers were designed to incorporate every meaningful advantage: classic black styling; safe, simple setup; lightweight handling; superb stability; strong, quiet performance; easy mobility; long-lasting service; an integrated backrail with safety crossbar; and a full fifteen-year warranty. But what you might appreciate most of all is the easy-to-reverse design. You can change your riser arrangement quickly and securely. Optional siderails attach without tools. 3- and 4-step models roll easily through standard doorways. From initial set up through final performance, no other riser performs like Signature.
