Bonmusica Shoulder Rest | This shoulder rest is height, width, and curve adjustable so that the player may obtain a precise fit to be as comfortable as possible. The curved padded base is easily manipulated to fit the exact contour of the player's shoulder, holding the instrument in place while promoting hands-free stability for easy shifting and vibrato. The foam padding is highly resistant to wear and is extremely comfortable. Unlike many other shoulder rests, the Bon Musica can be used by left-handed players. It also aids players who suffer from previous injuries or arthritis as it allows the shoulder to remain relaxed while keeping the instrument at the proper height and angle, rather than drooping forward.
