Ask HN: Do you have a home office (if you work from home)?

Am considering taking on a new job which would involve 2 days/week of remote work. My apartment is pretty small, I don't really have room for a home office. Most of my out of office coding is done on the couch, but I don't think that scales to 16+hours/week.

Do you have a home office? Why (not)? Any tips?

Thanks!
