I'm a college student in a powerchair (permobil M3.) I just started using a powerchair this year, and I found myself needing a bag that I could put on the arm of my chair that could hold things like a laptop and folders that would usually go in a backpack. I can't really bend backwards over my backrest to reach a backpack, so something like this was my only option. I looked everywhere, and I couldn't find any options that looked like they would last any amount of time or came in a fun color. I found this bag, loved it, and took the plunge even though the sidebar said it might not fit. It is literally the best armrest bag. I can fit my laptop, folders, books, my mouse: everything I need. It has a pocket on top that I use for quick access stuff like hand sanitizer and two at the bottom for things like pens and cables. I found the secondary set of straps on the bottom to attach to my chair perfectly. I buckle one on the arm of my joystick and the other to the metal part of my armrest behind the pad. Doesn't look ugly. Stays strong. Looks super clean! I just tuck the handle part into its little pocket. The only downsides is that the pen pockets at the bottom are a tiny bit of a reach and the bag sags a little where it hangs. Still, I'd absolutely buy it again and I've gotten so many compliments on it. Incredible bag.
