I occasionally read or watch videos on my laptop by "lying in bed, on my side, same as if I was sleeping, and" propping the laptop on its side. The L shape ensures it remains stable even without a pillow.
I used to read comics on my laptop that way until there was an app they used to have on the iPhone that would enlarge the comic text blobs when you clicked on them. Can’t remember what it was called but it was fantastic.
