Hanging chair options - show what your using or may potentially use

I am thinking about using a bathroom safety chair. It seems like you could do conventional BTC at the edge or use a pulley behind the chair and sit normally and still be in BTC. Has anyone used bathroom safety chair to hang? Here are links to what I am talking about.

Does anyone know if this is a viable means of hanging while sitting?

Here is the one I use,

I was using a large gaming armchair before it was awesome, very good, comfortable etc. as it is now in the interior of the State where I come from I don’t use it, maybe I’ll get it back.

Now I am using an old wood chair, indeed makes some marks on my back and some pain after I left it, nevertheless making gains.
