Common scenario for those who telecommute while traveling: You have to do extended office work in a hotel room, or in a rented apartment. Often there is no office chair, only a simple table and a standard chair, plus sometimes a couch and pillows. Back problems come quickly, sometimes already after a few hours.
Is there any remedy, such as a certain sitting posture?
Of course, one could just rent a desk in a coworking space, but not everybody likes the hustle and bustle in some of these places.
