Here's my solution.
I lock my iPad to portrait, take it out of the case and use a thing called an X-band from Onhand. It let's me lay on my side holding my iPad easily with a few fingers. My thumb is free to swipe pages, and my elbow is on the bed. When I'm really interested in the book I can read for an hour easily. I think I learned about this from Andy Ihnatko.
