I have some marimba students that are very tall, and they need to have the marimba higher so they can play without discomfort. Does anyone know how to raise the height of the marimba? I have seen someone using wood blocks under the wheels. Does anyone know the details on that? Thanks!

wood blocks work very well. You just need to make sure that they are flat and its a good idea to glue a rubber stopper on it that the casters can sit on so the instrument doesnt roll of the blocks.
