I had bad back issues for a while, and my employer got an ergonomic assessment for me - they used this company to build a personalized chair: https://somaergo.com/products/somacustom-chairs/somacomfort/somacomfort-sc-r4tbt https://somaergo.com/products/somacustom-chairs/somacomfort/... There are loads of options but that chair in particular has a design I’ve not seen elsewhere, which has a narrow back so your shoulders can be free to move/retract. I find normal chairs to be quite uncomfortable in comparison now that I’m used to this one.
