Can't think of any at this moment.
No way to anchor safely without damaging the arm of the chair.
I would NOT recommend this for a Lift-Chair because if you use it as directed, you will either ruin your chair or it will not be stable for safe use as a lift assist.
The tray sits too high if used over the arm of the chair. Even the cup holder is not large enough for a handled cup.
Stander Support was no help at all.
I did find another way to anchor it, but not the way the device is designed.
