Are there any office chairs that are as comfortable as a couch?

Are there any office chairs that are as comfortable as a couch? I mean like mega cushy. Intentionally too soft for an office chair. I *hate* office chairs because all of them are too hard, and they give me issues with hemorrhoids. I can work comfortably all day long from a couch, but I can't use my desk from a couch. So I want that couch comfort in an office chair package.
