For me, the greatest charm of remote work is not to get attached to a place, even in one room. At home, I work at the table, on the couch (on which I don't sleep), and on the floor. However, there is a strict rule - always monitor the health of the spine and posture! We underestimate this until we get stuck. Therefore, in addition to the basic rules and tools, I recommend adding reminders somewhere in front of your eyes about a regular warm-up.
Always do your job in comfort!
