Hmm.
Do not understand how this design would hang from back of chair?
Seems only flat surface use.
And lightweight.
I use clipa & heroclip.
Each holds 50lbs. & attaches to most surfaces /doors /railings /trees, etc.
Neither has damaged bags.

The clipa looks awesome I am ordering one for every single person I know that has a purse! Great price too!
