Looks cool, where did you buy it from?

I'd like something I can use while lying in bed.

I suspect I am getting a repetitive stress injury as a result of using my laptop in bed, usually by crossing my legs, then placing the front edge on my stomach and the back edge on one leg.

This is not exactly what you are looking for, but i have this one: https://www.google.com/search?q=rolf+benz+577

this may be an option for me. I have tried working on the bed, at the kitchen table etc. All of those cases give me a sore back or knots.
