biodegradable office furniture should be more of a thing. open source furniture design for an office and having staff contribute to building it could influence the culture in a positive way.
I think making your tech company staff make furniture is about as sensible as if the people who make furniture were also building their own software.
But as to open source furniture design ... I thought furniture was basically in the same position as fashion, where you can protect trademarks etc and particular patentable innovations, but that designs in general are not protected.
Hah, reminds me of 1990 Sun where I was handed several boxes of parts and told to make a sun4 VME workstation and bootstrap it from
tape. I think it was part hazing, part can this person ask for help when they get stuck and partly where is our documentation lacking. (Sun had excellent docs at the end)
I use a wooden chair for my home office and I find it more comfortable than office chairs, although it may not be a fair comparison since I spend most of the time squatting on it.
I do have an Aeron in my office. But since I largely stopped having video calls I confess I mostly work at my kitchen/dining room table in a wooden chair.
