the couch or the desk

I haven't been working at a desk since March. I have mostly been working from couches and armchairs. But now, I have decided to try the desk again.
pros: the view (I know I know but short attention span is a given here, it enables me to do the little I do, therefore the view is important), the impressive corridor of books and files surrounding the desk, with a nice wooden environment, the cute Louis XVI desk itself on which I work, the use of the big computer with its large screen and keyboard.
cons: the risk of ruining my back
