    Check that the ends of the (violin chin rest) clamp, where it screws into the armrest wood, are bent to a full 90 degrees, or maybe a degree or two more. Mine were bent to only 75 or 80 degrees, causing first contact with the body near the center of the armrest, potentially allowing it to pivot in place. To preserve the clamp's finish, rather than bend it further in a vise, I drilled a hole in some scrap steel and put that in the vise before, uhm, persuading.

    If the issue is really that the top's gutter is at such an acute angle compared to the rim (side), it should be relatively easy to grind or file a complementary angle into the rest's edge and then re-apply the (cork or leather) cushioning material. It need not be wider than the cushioning material, if even that much.

    Hope this helps.

    A small edge touching the instrument is all that's necessary. Like Philphool indicated, anything more is going to act upon the vibrating surface and will likely affect the quality of sound.

    Are your armrests falling off of the mandolins??

    Very interesting how well these armrests are working for so many other people.

    Maybe a picture of the problem would help.
    Duly noted. Pic in previous posted. Yes they do come off occasionally. I have to keep a tool in my case to reattach.

    Maybe you aren't tightening it enough? That looks like a Cumberland armrest, the same as mine (except mine is gold-colored). Mine also touches the top only with the edge of the cork, but it doesn't come off.

    I never used an armrest before but I just acquired a Campanella A-5 and I love the look and feel of this one. I don't know if I would like one any larger. Not sure if he would makes one separate from his mandolins, though.

    I position the armrest outer edge over the very edge of the mandolin, actually on the binding. I tighten down till resistance is met and then add just a bit more tension. The armrest will not move if I gently push on it, although I probably could move it if I really shoved on it. My armrest edge is closer to the edge of the mandolin than yours looks in your photo.

    Using this method, I've never had one come off accidentally, and have not seen any instrument damage other than occasional reaction to cork back in the days before I replaced all cork with thin leather. Could be slight marking even with leather on particularly soft finishes.

    My fairly thick (Mexican?) mandolin pressed on my forearm a bit, so I added a crescent of 1/4” thick closed cell foam, packing material, held on, double sticky- wise with blue painters tape, which has a weak and benign adhesive. Works fine for me, and easily removes. Wouldn’t have thought to do anything if I hadn’t noticed this thread!

    you want the top screws bent at 90 degrees. Few pieces of hardware are 90 degrees and sometimes the holes drilled are off a bit. I use a couple pliers and plastic tubing to hold and bend them.
