The Pedi Viola Elegante shoulder rest has a titanium alloy carbon fiber body. Very comfortable and lightweight at only 2.5 ounces; replacement sponge layer included.
Violin model pictured; viola model varies slightly-brackets have 5 screw positions
I was a long-time user of another, similarly shaped, much lower priced shoulder rest, but developed some upper back/neck pain and started looking into other options. It seems that for my particular set up this shoulder rest works better -- and I love that the feet don't seem to move (or to damage the instrument). Exceptionally lightweight, also. I would not have expected 1 oz to make such a difference, but the sound is much more focused and immediate. I agree with the previous reviewer that the instrument is more responsive than I have felt with other shoulder rests.
Love this shoulder rest - nice and light, very grippy feet. Seems to impede my viola's sound less than any other shoulder rest I've used. I feel that the instrument is a bit more responsive than with other ones.
