It is the hole through which the blow mould pumps air into the steel mould so that the melted plastic can take shape of the chair in the mould during the manufacturing process

For me, that hold could be not just structured for weight distribution alone.
That hole is designed for structural stability and also wind breaker.
The chair is designed to withstand some certain degree of wind force coming from all visible angle of the chair.

Considering it's light weight structure and the strength of the material used.

It should be able to counter external forces coming towards it.. that hole plays the role on the surface level.

That hole is to keep the plastic stool balance and firm so it doesn't break due to the weight on it

Pls nairalanders, what is the important of this hole pls?

OP, this is from a concept in Physics called Distributed Forces, it ensures the forces you exert on the surface are evenly distributed https://physics.stackexchange.com/questions/524983/what-is-a-distributed-force. Some Physics exist in everything around us, yes, I mean everything you see around you. I wonder when some people say what you learn in theory do not exist in practice.

The hole is for Structural integrity of th stool when you sit... If u notice, it is always round. If it were square, pressure from your weight while sitting will begin from the "Square edges" and cause the chair to crack... But as it is round, the pressure is evenly distributed...


What if there was no hole, what is the implication?

Why wud there be a hole in the one with backrest when the backrest already serves the purpose of absorbing the pressure frm the gluteal region?
When u seat reclining, there is less pressure under u.

Tinubu should come and appointment ministers and make other important appointments here. Brains full this platform. Your point is received and well taken.

The person I quoted made mention of vacuum, that the hole at the center of the one without backrest is to create needed vacuum when stacking. I got his points too, very valid.

That hole came from the mould case for easy extraction after moulding it during its production.

Nothing like round hole balance whatever when one sits on it.

They are notnproduced with the intention of carrying heavy weights on them.

The stands or legs has been positioned and aligned in such a way to every distribute whatever load will be on it.

Go on YouTube and search plastic stools moulding process.

It's an ergonomic design on the chair. It gives it balance because of the force that gets to the centre when it is carrying a weight or else it will easily break.

It's purpose is to make unstacking easy. If there weren't any holes, unstacking the stools would be impossible or rather they'd be challenging to un-stack at least. The holes are meant for the prevention of vacuum build-up. The holes relieve the air pressure when they are stacked, making un-stacking

The explanation is not likely correct, as sensible as it sounds.

Al you explained is why the hole should be round not square - but why should there be a hole at all?
thank you!!!!!

All of you up there should shout up your mouth and see the three essential reason.
1.They prevent the stool from breaking when you sit The holes in plastic stools are round and not square for a reason. It’s to maintain the structural integrity of the stool and to prevent it from breaking when you sit. If it were a square or any other shape with angles, the force would be concentrated in those places and increase the risk of cracking. Circular holes, on the other hand, spread the force evenly.
2. For easy stacking If there weren’t any holes, stacking the chairs would be impossible. Or rather, they’d be challenging to un-stack. The holes are meant to prevent a vacuum from building up and to relieve the air pressure when they are stacked, so un-stacking becomes easier.
3. For your finger to go through
Yes. The hole serves an additional purpose of making carrying more comfortable.

But there’s also a catch there; make the hole too big, and the chair would lose its support. Make it too small, and your fingers cant squeeze through! Wow, imagine all the engineering that goes into those cheap plastic stools.

That’s an emergency exit and in case mess just show unexpectedly so e go just deflate downwards and nor smell much.
so the chairs in your home get such holes or you don’t mess ? Some of you sounds so dumb and f00lish .

Such circular hole doesn't exist on seats. It only exist on table. Yet, You don't sit on table. And what is there is never a seat. Obviously it is for umbrella.

WRONG! I'm into plastic manufacturing, that hole there is the point where molten resins enters the mould to form the chair. It is called RUNNER.

You have a point.
But going by this point, the hole should be wider than it is in order to evenly distribute the sitting pressure to the square edges and this will make prolonged sitting a little uncomfortable.
A little research shows that the hole is to provide vacuum when stacking the chairs.
This explanation is scientifically feasible.

Logically, you are on point but something is missing.

Actually, the hole:

1. Expels the vacuum between two surfaces thereby releasing the stools from suction pressure should they be stacked. (like in syringe or glass sucker working principles)

2. It's easier to pull out with a finger if in stacks.

3. The stools could be locked together for security purposes.
