Inglesina 2010 Fast Table Booster Seat ($70) 2 Phil and Ted's MeToo Chair ($50, see our reviews here and here) 3 Zooper Hook-On Chair ($50) 4 Chicco 360 degree chair ($70, Chicco makes a few hook-on chairs including the Hippo and Caddy) 5 Feeding Friend Portable Hook On Chair ($45, this chair is temporarily out of stock at many places we looked at and we wonder if it's being discontinued?) Phil and Ted's has a new hook-on high chair coming out called the Lobster. It's no longer on their website so we're not sure what the story is or when it might be available. Are we missing a hook-on high chair that you like? Let us know in the comments. And feel free to leave a a mini-review of any of these in the comments, too.
