Our toddler sits on a couple of phone books (taped together no less!) at the dinner table, so I thought this booster seat styled as the yellow pages was hilarious. Since they don’t have the Space Needle on them I’m not sure our son would actually sit on them. As he often points out, his booster seat has the Space Needle on both sides. I doubt he’ll ever have a need to use a phone book for its intended purpose.
