Folding Arm Chair How Can I Rig The Arm Rests On My Camping Chair So They Don't Slide Down?

How can I rig the arm rests on my camping chair so they don't slide down? - folding arm chair

I need a patch for the arm of the folding chair. It is a traditional seat that folds and slides into a pocket. The armrests always falls, usually when I hit the chair, his arms over the house bin, even if only a drink in the cupholder. Suggestions on how not fall within the same platform in order to? I want to buy a new president, but the only thing that seems that what I seek is $ 65 and will not commit to a chair on the lawn, if $ 65, no simple solution to the mine.
