I suspended a kindle over my bed on two 2-meter rails used for reinforcing wall edges. Best reading I did while recovering from leg injuries, but risky as you mentioned.
Then for ultimate convenience (laziness) I connected a bluetooth presentation clicker to my iPad to turn the pages for me so I didn't have to keep reaching up or take my arms out from under the blanket on cold nights. In two years it's never dropped.
Is there a way to use the clicker with the kindle?
I keep thinking of assembling about the same thing, but missed the warm-blanket factor. Now I definitely must do it.
