Not only that, but many of these setups trade an ergonomic chair for a hard floor. I'm surprised that more consideration does not go into floor mats as seen in other jobs requiring long periods of standing.
If anyone's looking for a recommendation, I've found industrial antifatigue mats (found in machine shops and the like, mcmaster-carr sells some as would most industrial suppliers) surprisingly comfortable for standing on all day.
Indeed. If they're made to be comfortable for a heavyset man holding powertools wearing steel-toed boots, it's definitely going to feel good in comfortable clothes and shoes! :-)
