Don't attempt this in a small car!
Booster is very large, fairly well padded ( I did expect a bit more, considering the price and other reviewer's comments). My grandaughter is tall for four and the traditional harness car seat was simply too small for her long legs (and her little brother has taken it over, anyway.) She tells me that she is very comfy and LOVES being up a little higher and able to see everything going on afround her. Had no difficulty installing in my RAV4, but even that decent size back seat is now taken up entirely by two car seats, so heaven help the parent who drives a little car!
ProsI bought the Performance Booster based on its outstanding safety ratings and the reputation of the manufacturer. (*Another son-in-law, father of my third grandchild was doing his own research and came up with the same opinion.)
Solid, well made, very comfortable seat for four year old grandaughter. It should last well through her time and take on the two litle grandsons in their turn.
Easy installation in my RAV4.
ConsSeat IS huge! Between this booster seat and the tradtional harness car sear for the youngest members of the clan, my "three passenger" back seat is effectively rendered useless to me for any adult passengers wihout removing both car seats.
Anchor straps for Performance Booster should be adjustable so that they can be tightened, preventing the seat from wobbling when not occupied and held in place by shoulder belt.
