Love it!

I bought the Chicco Caddy Hook On High Chair as an alternative to a standard high chair and have been very pleased.  Many high chairs are easily over $100 and this was less than $40 so it was a no-brainer.  It's very light weight, mobile, and compact compared to a high chair so transporting it between locations is easy.  The seat material seems very resilient to damage and easy to clean although we haven't had occassion to do so as yet.  I would place a cushion of some style on the seat for the baby's comfort.  Additionally, a towell or small blanket can take up excess space between the baby and the seat back. We started using this when our child was at about 12-15 lbs and 5 months of age when she was beginning to sit up pretty well.  Just dump a pile of toys in front of the child and they are occupied for quite a while (at least until they have all made their way to the floor).  The only precaution is that you should protect your baby from kicking the ends of the screws that secure it to the table as those little legs are always swinging back and forth.  I rolled up a pair of athletic socks and then placed a rubber band around them such that they would cushion my child's feet against the ends of these hand-adjusting screws.  I have used this on two different dining room tables and found no difficulty in attaching it to either table.  It does not appear to damage the table either.
