I built one of these for backpacking trips for a little less than $5 for a wooden disk, a couple plumbing bits and a clip belt. Silly looking when you're walking around with it, but infinitely better than sitting on a wet log next to the campfire.
Also, having to balance on two axes with the milking stool is much harder than with the chairless chair, which only requires you to balance on axis.
I think with your feet wide you enter a pretty stable tripod stance. And you could easily adjust the length of the chair or give it feet. But since, I presume, neither of us has tried either device, it's all academic, isn't it?
For cultures that habitually use squat toilets, everyone can hold that position; but for other cultures many people can't.
But hey, you know with the right cargo style pants you could just conceal the halves and...
If a future iteration is cheap, light and can be worn below clothes, I could really see this catching on.
Straps holding it in place, only two pads beneath your butt and no back support.
Maybe in a two minute demonstration it's ok, but wear it all day and I bet it will feel like a jail.
As for the assembly worker video example, it doesn't seem like a well-thought use case.
Why not use a stool? Cheaper and might have some back support.
Also, off the top of my head:
What happens if you forget and lean backwards, even a bit ?
How much time does it take to put it on and take it off?
How easy is it to put it on in a slightly incorrect manner and twist and break your leg?
Look at what the guy is doing. A stool will probably only cover 30% (if that) of his work.
> What happens if you forget and lean backwards, even a bit ?
What happens if you are on a stool without a back and lean backwards?
> How much time does it take to put it on and take it off?
It sounds like you only put it on once per day and just leave it on disabled without significantly impacting your movement.
Hell, I want one to help me do the dishes. There's somewhere a stool wouldn't make much sense.
“Even if you are doing the recommended amount of moderate to vigorous exercise, you will still have a higher risk of mortality if you’re spending too many hours sitting,” says Dr. JoAnn Manson, one of the study’s authors, and chief of preventive medicine at Harvard-affiliated Brigham and Women’s Hospital.
Btw, The article said that 8+ hours and it applies to woman.
