    Why do rolling chairs have 5 wheels?

    God damn my leg and elbow hurt.

    But anyway, it's pretty obvious that I just fell over and my first thought was "6 wheels would have prevented this".

    Does anybody know if there is a specific reason to have a specific number of wheels on the chairs? Would it be too hard to roll or something?

    I would imagine that 5 is the least number that still provides acceptable resistance to falling over. Less material = less cost.

    all about stability. could prolly get away with only 4 wheels. but im sure companies spent big bucks to research these things. cost of materials + design = 5 wheel stability.

    I was going to say I'd pay for an extra wheel, but I probably wouldn't based on the fact that I find my own fuckups amusing.

    I just think five is the "magic number" for stability. Four/two/three wheels, weight is less evenly distributed, easier to fall. Six and up... I dunno. Maybe some fancy physics makes it easier to tip over because of more points that can align or whatever?

    Dunno, pretty damn good question, now that I think on it :P

    I'd love to get one with 2 wheels:P It would be great exercise balancing that thing while doing something on my computer.

    Well, an odd number provides more stability in one point in that there can't be any right-angular alignment of all the wheels, but more wheels itself also provides more stability in that the allowed space for two wheels to be aligned with each other is smaller. 7-wheeled chair!

    You start funding the production, and I'll sit on your lawn with my wallet in hand!

    Take it slow, make it happen, set a course.

    Make one model with 11 wheels, one with 7. Sell them in 7-11s. Marketing is done, I demand 20% of the profits for my genius marketing job.

    Just buy a recliner and place it in front of your computer desk then find a plank of wood to use as a keyboard/mouse tray.
    Or even better yet build a custom computer desk on wheels that rolls into the recliner.

    Works best if you have a recliner that doesn't rock and does not recline unless the footrest is extended (should also be a cloth recliner so you don't stick to it"

    I did it for years when I was a teenager and the recliner doubled as my bed a good portion of the time.

    Both of those options sound far worse than dealing with the occasional tumble from my chair. An immobile chair is a no for me because I usually sit very close to my desk. I also don't have a keyboard/mouse tray because I fucking hate them.

    A mobile desk is just asking for horrible things.

    Probably the most important thing for stability is the length of the legs, not the amount. But now that I think of it, pretty much every office chair I have seen has the same wheel base radius. Hmmmm...

    This hasnt happened to me ever actually. Sometimes I lean back real far in it too to reach something since I'm lazy, and there is a rug behind my chair so it's hard to roll it over. But my chair never tips

    Do you have a small office chair or one of those big leather ones (I use the latter, the cheapest one on the market though) and it's pretty steady

    Any wider and you will be kicking the legs with your feet when you sit in it. I already do but I'm taller than the average. The legs shouldn't go out further than the front of the seat of the chair.

    Well the legs aren't going to stick out much from the seat. I suppose they could, but it would be inconvenient.

    Big and black leather, like the kind you can turn around and say "I've been expecting you." in.

    Erm if it was 4 movement would be harder, e.g. to turn on the chair not spin,

    6 would act the same as 5, so its a waste on costs

    and lastly, how did you fell over on a 5 wheeled chair oO

    I havent fallen over in my 5 wheel chair, however it has consumed a few of my blankets =3
    I play many games. WoW, Rift, D3, PoE, SC2 I will not criticize your game choice if you don't mine.

    Funny, my first thought would have been "Ow, fuck! My leg/elbow!"
