My just past one had a desk in the corner but she sat in a chair and there was a regular large couch across from the chair with a coffee table separating the two. I hated the couch and thought there should be chair for clients too. It seemed like a power thing. The coffee table was comforting to have as a separation.
The current one has a desk, rolling desk chair, regular chair and small sofa. I usually sit in the chair which is right next to the door and she sits in the rolling desk chair facing me. But she does roll as far away from me as the room allows for the sake of my comfort.
Neither had a lying down sort of couch.

I did try one earlier this year who had the whole black leather no arm lie down on couch with a chair behind it. It creeped me out.
