I walk into my home office, as my company like many went fully remote during COVID and stayed that way. However prior to that I had two options:
I could bike, it was about 5.5 miles with bike lanes the whole way (until downtown, where the roads were shared but marked for bike traffic). I think it took me about 20 or 30 minutes, but honestly I don't remember anymore. Going home took longer as it was uphill compared to the way in.
The other option was I could take public transit; there were both buses and a light rail and I greatly preferred the latter. When I did that, it was a 5 minute walk to the light rail, about a 20 minute ride, and then a 10 minute walk to the office.
At the time I lived in a decent sized US city, but since going remote I've moved somewhere smaller. However I really loved having good public transit, and if I ever had to go into an office again either being able to bike or public transit in is a big requirement for me; I can't stand car commuting: it's stressful and wasteful, and has a very negative impact on cities for those that live there.
I have a sit/stand desk and so I spend about half the day in my chair. I use a Steelcase Think; I like how it's relatively simple but still has a lot of articulation in its armrests, which makes it easy to get decent arm support where you need it. It's very sturdy and of nice quality. my only complaint is that I wish its back didn't have an inch of give before it hits the lock point at the furthest forward point, but this is really very minor.
if you live somewhere that you can go to an office surplus store, I'd super recommend doing that. I picked out this chair after trying a bunch out, and it was much cheaper than MSRP since it was used. they had like 20 different models and perhaps 5 of this one, and I picked out the nicest of the bunch.
