Lounge chair book holder

My "search" attempts are failing me and I need help. Some time ago there was a thread on the dimensions of the beach chairs at Club O and some designs on making a book holder that straddled the chair made out of towels. Can someone point me in the right direction, with possibly a link to the thread, or any other words of advice? Thanks.

Check out this thread, as well as the other thread I just replied to.

One of the best book holders is called arms and hands.
Ya want someone to turn the pages also.

I can see how something like that would be very helpful... but I have to add this to my list of First World Problems.
