Overall its a great high chair! I love that you can move the seat higher and lower and lean it back or forward. It's really a great high chair for both my two year old and my 6 month old.
For my big one, I remove the tray and move it into the table and it works great.
I do find it quite hard to move it especially when there is a child in it. Its hard to lift the back so that the wheels will move. Also, the tray does not click in well, and stay in the back legs when you want to put it away.
