Wolfe shoulder rests are unique in their flexible backplate design. They can be adjusted to any angle and any width. They're preferred by many teachers for growing students because of their customizable design.
The main part of the shoulder rest is made of comfortable rubber, on top of a flexible aluminum plating which makes it possible for the player to shape the rest to their own shoulder shape. It is very ergonomic. This rest comes with two plastic spacing tubes which allow the arms to be stable when put into the highest position.
