One of my friends offered us this booster when we had our 2nd kid. This is sooooooo useful!It adapts on mostly any chair you got to make it higher so the kid can sit. Not good for very young kids but my 2 yo use it on everyday basis. It's really sturdy and stable,if you move the chair it's gonna stay on. It's so small it's super easy to transport when going on vacation or on a trip
