Are you more productive coding outside your desk?

I’ve noticed something weird: I’m actually more productive coding on the couch or in bed with my laptop than at a desk. It feels less “formal” and I get into flow faster. For complex tasks I still sometimes switch back to a desk, but for many things this setup just works better for me. Do you have a “non-standard” coding spot that works better for you? Or is the classic desk setup still king?
