I just looked this up on yahoo, didn't know what an epillow looked like. The second listing was for an ob/gn in Fl, Steven E Pillow. Poor man, I'm sure he is hoping these don't catch on.
Haven't used the epillow before, but I got a Book Seat a while back and it seems to work great! Normally I use it in bed. I got it from The Gallerie, an online store in Australia. (thegallerie.com.au)
