can anyone explain the difference between a conventional four-legged chair, and a five-castor office chair, in terms of my ass?

i'm guessing that with a five-castor office chair, since my ass is basically sitting on a metal plate that is being held up by a vertical pole, that more force/pressure is being applied to my ass, i.e. it's all going to/from that one point/line

but because with a four-wheel chair i'm sitting on a frame that is being held with four legs, so that the force/pressure is being distributed better with a four-wheel chair, i.e. away from my ass

is that right?

or is there literally no difference?

bonus points: draw force lines

optional: draw my ass

same thing

[Anonymous No.7465478]

>>7465436
Uh actually since the metal pole is attached to a metal plate which is in turn attached to a larger base, the force shouldn't be concentrated in the centre any more than a four-legged chair.

There's probably some complicated shit going on which would be required for a sufficient proof, but you can just take my word for it if you like.

>>7465478
That said, sitting is an unnatural position for humans, you should really get a standing desk. This makes choosing a chair unnecessary, as you won't be needing a chair.

[Anonymous No.7465486]

>>7465478
the force on the floor sure, but what about my ass?

>you can just take my word for it if you like
that doesn't sound very scientific

that said, i just had an epiphany

perhaps on the office chair a metal plate is my ass cushion, but on a four-wheel chair my ass cushion consists of a good deal of air

>>7465487

[Anonymous No.7465490]

It's not very scientific, but I bet the makers of chairs probably test this shit.
If you want to science it up, cover two chairs in pressure sensors and sit in them, comparing the gathered data afterwards.

>sitting is an unnatural position for humans
uh, no

[Anonymous No.7465771]

>>7465489
What you say would be true if the seat of the chair were a fucking hammock.
It is hard, the soft cushion goes on top of that, there is no difference to your ass. The only difference is how the chair experiences forces, I've had two office chairs break already, because a single rod will bend and experience metal fatigue over time. That combined with a poor welding job.

By the way, get a recliner in style pic related, got one recently and it's way better and more comfortable than a traditional office chair.

it is

basically an office chair is a stool, and a (good) chair is an ass hammock

Humans have sat for all ages. Nothing unnatural about it.

Have you ever tried standing all day every day?

[Anonymous No.7465807]

>>7465804
Your chair in the pic isn't a hammock, it is supported on all sides. What's underneath that again doesn't matter.

[Anonymous No.7465808]

>>7465805
>Humans have sat for all ages

But that's wrong. In fact there are large parts of the world where people basically never sit. Just stand, squat, or lie down.

[Anonymous No.7465810]

>>7465808
Where?

[Anonymous No.7465811]

>>7465485
no no no standing is also unnatural you should get a running desk
just duct tape your computer to a deer and it'll do fine
it's really important that you make sure you aren't standing in one place all day because if you do, that's unnatural and bad for you, humans aren't made to spend all day standing around

[Anonymous No.7465812]

>>7465807
so it's a superhammock

[Anonymous No.7465815]

>>7465812
Then what is your question, You're sitting on a crappy superhammock you call a good chair. Now what.

Well, southeast Asia, for one. When I was in Vietnam the only chairs I saw were in tourist restaurants.

Better than what? I've already said the structure that is holding up your superhammock doesn't matter to your ass.

a superhammock vs an office chair (which is basically a stool i think)

Ok, so it's natural for viatnamese to squat. That doesn't tell you anything about if it's unnatural for me to sit you fucking quack.

[Anonymous No.7465828]

>>7465821
Depends on the particular model. Most have a hard plate that has a cushion on top. If you have a good cushion then it's gonna be as comfortable as you hammock chair, or more comfortable, depending on your preference.

>>7465828
so you're saying that if it has any hard plate it's the same regardless of whether there is a single leg in the middle holding it up, or if it's supported by four legs?

and you're also saying that an ass hammock > any plate?

Exactly.

>and you're also saying that an ass hammock > any plate?
Yeah, a hammock is gonna be softer to sit on than a hard plate of course. But I would personally rather sit on a good cushion. Some people like water beds, some like hammocks, etc.

So then what are you seriously saying? I can't even tell. It sounds like you are saying Vietnamese aren't people? But that can't be right.

[Anonymous No.7465855]

>>7465844
I'm not Vietnamese. Most people in the world sit. If some people in the world choose to not sit, that doesn't say anything about it being unnatural or not. I can tell you that it would be unnatural and painful for me to not sit.

[Anonymous No.7465871]

>>7465855
>If some people in the world choose to not sit, that doesn't say anything about it being unnatural or not.

I agree with that, but it contradicts what you were saying earlier, that everybody sits and therefore it is good to sit.

> I can tell you that it would be unnatural and painful for me to not sit.

How do you know?

There's a lot of evidence recently coming to light that sitting down for most of the day, like most of us (including me and obviously you) do, is actually quite bad for us. Google it.

[Anonymous No.7465881]

>>7465871
>you were saying earlier, that everybody sits and therefore it is good to sit.
I never said that, you inferred it.

>How do you know?
Because I've tried. I had to quit a job because I had to stand all day there.

>evidence recently coming to light that sitting down for most of the day
That's not actually what it's about. It's about lack of exercise.

[Anonymous No.7465884]

>>7465881
>I never said that, you inferred it.

Because it was the only possible reasonable inference.

>Because I've tried. I had to quit a job because I had to stand all day there.

So what? Standing uninterrupted all day means sitting can't be bad? Bad logic.

>It's about lack of exercise.

It's specifically NOT about lack of exercise, actually. Sitting for long periods is associated with bad outcomes even for people who get lots and lots of exercise as well.

[Anonymous No.7465887]

Sitting down for extended periods of time is worse for you then smoking regularly. Prove me wrong

What would be the alternative? Lying down?
>Hurr durr you have to lie down you can't sit because it's dangerous for you.

>bad outcomes even for people who get lots and lots of exercise as well.
Because they don't move when they sit, and that means a lot of non-exercise.

[Anonymous No.7465910]

>>7465888
>What would be the alternative? Lying down?

Mostly standing, with brief breaks (sitting or squatting).

>Because they don't move when they sit, and that means a lot of non-exercise.

I'll repeat, these are people who get lots of exercise.

[Anonymous No.7465914]

>>7465910

Dumb answer. Then you're saying sitting is good after all.

>I'll repeat, these are people who get lots of exercise.
I'll repeat, they don't get the prolonged low intensity exercise over time.
Or are you seriously claiming that there is something inherently harmful being in a seated position.

[Anonymous No.7465917]

>>7465914
Not inherently. But I think rhe question here is about moderation and how much time is spent sitting. Being in a state of complete rest for extended periods of time is bad for your circulatory system and muscles

[Anonymous No.7465922]

>>7465917
>Being in a state of complete rest for extended periods of time is bad
There, you got it.
Not fucking sitting in itself.
And there is no good alternative to chairs to rest after standing for a while. Therefore saying sitting is bad is like saying water is bad because everyone who drinks it will die.

shittily made gas canisters.

on any gas canister chair, the whole weight of your body is held up by a gas piston compressing air

if your chair was made in china with garbage parts and manufacturing, sometimes a piece gives out and 250 pounds of force rockets a piece of metal up your anus

No, the sitting position itself is not good for you.

Sure, in the same way that eating too much unbuttered, unsalted popcorn is bad for you. Point being is that if it's having a negative impact on your health, you're doing it too much.

OP, I have a PhD in chairs

The human brain is not evolved to sit on metal, therefore its much more natural to have a wooden one

Also, jews are wiring the office chairs so that an algorithm will analyze your farts and slowly moves you to a direction where chemtrail can enter through your windows

I think everyone should just shut the fuck up about this until NASA finishes it's study on extended periods of laying down and muscle atrophy. Some of them will be exercising and some will not be:

>>7465987
I did hear somewhere that squatting while shitting is better for you then sitting while shitting (because ancient humans didn't have toilets so, in terms of evolution, the squatting position causes less stress to the sphincter). That being said, I've never heard that sitting down has any downsides, just that shitting while sitting down is harder than shitting while squatting.
