I want to C.T.B using the stairs as an anchor point but i have some fears

[Haibane-renmei-reki]

maybe it's just my O.C.D, however my stairs're made of Iron and are dureable thankfully, but i still fear the stairwells are too narrow and i fear the treads will hinder the chair's job and my feet will touch them (i prefer full suspension hanging) here are pics of my house's stairs:

Your question isn't clear. It's not clear whether you're asking where to place the chair, how to position it on the stairs, or what exactly the problem is. Please explain what you mean more clearly.

i expected ppl would say so, i am really sorry for causing confusion, but yes, i meant to ask how to position it on the strairs, BTW on another note, i just tested some stuff with my mom's scarf since i don't have a rope yet, i can see it working thankfully, my O.C.D is less bad now, although of course i won't attempt anything without a proper rope yet, i just hope the rope will work just like the scarf, these narrow stairwells are making me stressed...

It doesn't matter if the chair falls perfectly, gets stuck, or just tips sideways. What really matters is that you lose ground contact and the rope stays tight under your full body weight.

If the knot is solid and the anchor point holds, then the moment your feet are no longer actively supporting you, the mechanism is already in motion.

You're not facing a technical limitation here — it's OCD. You're trying to engineer a perfect fall when all that's needed is that the support under you vanishes.

The chair doesn't need to fall "cleanly." It can hang, catch on a stair, or not even fall fully — none of that stops the rope from doing its job, as long as your body weight engages it.

Just make sure the rope is secure: height, strength, knot. That's what counts.
The rest — the path of the chair, the angle, where it lands — is just your mind looping on irrelevant details. Nothing more.
