We've got a Mothers Choice one that we got from Target I think.
Things I would look for if buying another one -
*Easy to clean
*5 point harness
*No footrest - they aren't necessary and once they reach toddler age they use it as leverage to push themselves up
*Removable tray (preferably dishwasher safe)
*Height adjustable - this is really coming into its own now with DD at an age where she wants to sit at the table with us so we can pull the height of the chair up and down to suit where we are eating.
*Good wheels so you can move it around easily.
Happy shopping!
