I had never seen these before my trip to Cleveland earlier this month. It's the neatest thing: a cross between a pillow and a bookrest. I was so intrigued that I had to buy one (I got the orange suede, though I was pretty close to picking up the one pictured here).
Now that I've tested it out, I can say that it's especially good for hardcover books and that the tassel makes a great cat toy.
I'm definitely gettting one for my mom for Christmas... it's "the perfect gift for a nomadic reader" (the tag says something along those lines).
Go to the Peeramid website to learn more about this unique bookrest.
