My Ts office has a long couch without arms but it's flat and there's another chair that is a swivel type across from the couch, so I have a choice there.

My T sits in another swivel type against the far wall.....The couch does NOT face the T's chair, so if you choose the couch, you're looking right out the window, which I don't like. I also don't like the swivel chair.

Seating isn't my top concern right now, but I really don't like this set up. I even have a fantasy abuot bringing a folding chair!
