Have the seat of my car for my smallest grandson bought (now 14 months). Use it for about 1/4 year about 1-2 times a week. The installation was relatively simple. Is to deal with for a woman alone ;-) The little one felt comfortable right from the start in the seat. He has an eye on everything and it seems to be convenient. The buckling folds now also super - he lifts by itself the arms so that the "table" can be attached. I can actually seat with a clear conscience. I have a very "safe" feeling and think that the little man is in good hands in the seat.
