Portable folding tables are a staple in every home because of their versatility. If you need a desk, it doesn’t matter where you are - a folding table can be precisely what you need. Make sure that the folding table that you plan to use as a desk is a good height - around 30-35” from the floor, instead of one of the taller variants; this will help you have the proper ergonomics as you sit at it.
It might be helpful, too, to pack a few pads for the bases of the table legs along with your folding table, so you can level out the table even if the floor in your temporary office space is uneven.
