This book holder works just as I had hoped it would, and I love everything about it. It makes reading in bed so much easier and using it on my lap holds the book/device at a comfortable reading angle! It holds an Ipad (classic size) or Kindle (HD Fire) easily (the photo above) or am extra large hard cover book just as easily (photo below).
Here is that little pocket that I added. I'm so glad that I was able to add at least one!
