A Perfect Compromise
There isn't room in our home for a full sized high chair and because we like to get out of the house often I knew a portable booster-style seat was what we needed and I was willing to pay a little extra to get it. We currently use this seat for our 6m old (unassisted sitter) and we love it. Yes the whole thing is plastic, but it cleans easy and is still light and sturdy. We have used in both on a chair and on the floor with great success. They tray is smaller that some others but it is about as big as you could get and still travel easy. My 2 biggest "issues" are that the tray sits pretty far away from the body since she is so young and leaves lots of room for food to drop. Also, there isn't a way to attach the tray to the chair while its folded fro transporting. It comes with a bag to hold the 2 items but it would have been very simple to make a connection so you could leave the bag alone.
Proscompact, travels well, easy to adjust
