Office chair technology also has really advanced since then (looking at the chair on the picture, which is commonly seen near computers in photos of this era)

Indeed, the Aeron chair, which became a design classic and the apparently the best-selling office chair ever in the US, only came out in 1994. So about the same time as the web. Not sure if it’s the only office chair design with a dedicated wikipedia page? https://en.wikipedia.org/wiki/Aeron_chair

Depends, is the deck of a battleship an "office"? https://en.wikipedia.org/wiki/Emeco_1006

Theres also https://en.wikipedia.org/wiki/Mirra_chair. (wikipedia has a page for "list of chairs", but not all of them have a dedicated article)

probably my least-regretted purchase (excepting my dog) is my used Aeron that I bought in ~2014 for $300. Still use it daily
