Around here they switched from uncomfortable hard-plastic-shell-seats to comfy leather seating...

I guess it works both ways.
Probably fastfood restaurants that get more customers (i.e. McDonald's & burger king), would invest in something to limit guest visitation, whereas, a coffee shop competing against starbucks or whatever, would want something to attract as many guests as possible.
It's amazing how atmospherics can affect people (scents, colours, decor etc).
I wouldn't call this chair ergonomic.

Looks just like the ones they have at school... hard wood, with scant pieces of metal.
The worst ones were these metal ones which had small wooden writing tables on the right side -- my friend, who was left handed (in writing anyways), had to use two. The metal really dug into your back.
Annoyingly enough, they got all the teachers new iPads (yeah that's VERY expensive), but no, they can't afford new desks or chairs? Even some soft chair covers would be nice.
I should too. My home computer chair's in even worse shape than the one you got. But my work one's nice. Orange fake-leather and chrome all the way.
But if I made myself a wheely recliner, it'd have a footrest.

On the Internet I actually found a photo of the same model chair as my home computer chair. The only difference is mine's threadbare, and the back fell off and is held on by an old carriage bolt I scrounged out of my workshop that's an inch too long.

NOTE-That's NOT my chair, NOT my spill, and NOT my bed!
But you have the same rubbish bin?
