My T has two chairs and a couch that kinda form a "U" shape both of the chairs swivel. She always sits in the same chair with her right leg under her and the other crossed over her knee with a pillow in her lap that she uses to keep her notebook on and I sit indian style as closed up as possible in the corner of the couch with my shoes off diagonal from her. I've thought about sitting directly across from her but have never done so. We are about 3 feet apart in our normal seating arrangement. I usually hold one of the pillows in my lap while we talk. The only time she's sat different is when I'm in distress she'll keep both feet on the ground and lean towards me.
