What is the easiest way to work in bed with a laptop?

So I have a normal bed that I can't adjust. Does a kind of table make sense anyway or how do you do that?

I put the pillow against the wall, lean back in there, and then put the laptop on its feet, with the blanket in between, when the laptop is hot, or the room is cold.

I have a laptop table and sit on two pillows. A small pillow and a larger one so that I'm a bit crooked
