Here's what Alex Looney has to say about his school's FR-36 Choral Risers.
The FR-36 Choral Riser is perfect for school choirs because it can be set up easily with just one person. All the parts are mounted to the frame so no tools or transport carts are required. All you need to do is roll it into place, unfold it, and engage the locking casters and you’re good to go.
