My current t doesn't have her own office, and we rotate through 3 different ones. 2 have more comfy chairs, the third isn't as comfy. Previous t had a couch that I sat on. T's before all had chairs of varying comfort. My favorite t actually had the most uncomfortable chair *ever*, so we often sat on the floor (though I think she had a few asd clients who preferred the really hard, stiff, upright chairs). She also had a cushy office/desk chair for clients, but it tilted back real fast when you would sit down, which always made me feel like I was going to fall through the wall behind me so I didn't use it often... I miss the comfy couch.
