I come from a time and a place where I judge people by the content of their character; I don't give a damn if you are tall or short; gay or straight; Jew or Gentile; White, Black, Brown or Green; Conservative or Liberal.
But mines never fallen over, hmm.
Do you roll around a lot? I barely move my chair really.

In the mall those doors that are supposed to automatically open for you were just closing as I approached, they stopped closing with about a 5-10cm gap and I assumed they'd open again but they did not.

This is the one I have, from Ikea:
It's stability is awesome, probably the most stable I've had. And I frequently lean waay back and put my legs up on my desk when I watch something on YouTube, etc. Never even had the feeling that it's starting to tip, which I often had with my previous chair.
Ummm Howard. What the hell man!
149 Euros=186 AUD
My chair was about $180, I could have bought the above if it was about $180!
Tipping happens when CG goes over the support base. Number of legs only effects the effective shape of the base. What's all this right angular alignment stuff?
Op: 6 legs is not gonna add significantly to stability. A pentagon vs a hexagon of equal centroid-to-corner length look pretty similar from an overall area covered perspective, and that's a pretty good analogy for 5 vs 6 leg stability.
because the five wheels represent the five points of a pentagram, allowing the chair to channel the powers of hell to either retain it's balance or cause you to fall over in retribution.

It could have 27 wheels, if you squirm in it a lot and bend and so on you can still fall.
It has 5 wheels because that is actually its leg and arm, an army with 5 fingers. It's attached to the head of the chair, which is the chair itself on which you stand, It's bend in a straight angle, but not because humans made it like that, but rather because it's an open mouth, ready to eat you.
You see, those chairs are in fact creatures. They are found, thrown meat and when they open their mouth they're thrown in plastic. Then a material cover is put so you don't see the ugly creature under it since you can still distinguish the features.

Let's assume that when you fall off your chair, it's because you leaned in the direction between two of the chair's legs. This is where the effective base size of the chair is at it's minimum. See picture below.
(behold my epic Paint skills)
Now take a chair with 6 legs instead of 5. Assuming that both chairs have legs with the same length (radius r), the effective radius between any two legs is longer on the chair with 6 legs (a < b).
So with the 6-legged chair, when you lean in the direction between two legs, your center of gravity has slighly more distance to travel before it causes the chair to tip.

Bergtau's Law: As an online discussion grows longer, the probability that somebody will mention Godwin's Law approaches 1.
Hitler wasn't all bad, I mean, he DID kill Hitler.
An accident is something that you did not mean to do at all. A mistake is something that you regret doing.
make perfectly circular base for chair.
make hollow area inside said base.
fill hollow with multiple "balls" of some sort to allow for movement.
the most difficult part would be designing the "balls" so that they allow for fluid movement in a desired direction instead of being completely uncontrollable.
i can't imagine that this is too difficult a task.
isn't there an engineer anybody knows we can set to this task?
I don't buy that it's just a cost issue. If it was, then premium chairs would have more than five wheels. They don't.
Having too many wheels makes the chair more clumsy and leaves less room for feet/other stuff. I think having five wheels is just the sweetspot for maximum stability but minimum clumsiness.
