The book wedge is a great devise for propping up your kindle, ipad, other electronic
gizmos and your books. I personally like it for the books! As do a couple of my boys.
The book wedge is a lightweight inflatable tool that you can easily take with you when you travel or even just go from room to room with it. Much lighter on your lap than a lapdesk or something like that. Just enough angle to it to keep your book in place. With thicker books you will need to hang on to your book as it tends to tip a bit.
The only trouble I had with the book wedge is that the material on it is the type that attracts lint very easily. With a cat in the house I felt I was always picking fur off the book wedge and the dark blue color made it very noticeable.
