I'm at an company where managers all have couches in their offices. When you meet with them, they sit in high backed comfy chairs, you sit on the couch.
I know how to sit at a table, but on a couch, find myself sitting either on the edge, with my elbows on my knees as if I were sitting on a bench in a dugout, or if I sit back, I feel as if I'm too reclined. Sitting in the middle ans trying to sit up straight feels unnatural and awkward.
So, question is, what's the most professional posture when sitting on a couch?
