Product Reviews : Car Seats From Four Years : Silver Cross Navigator

I bought this because its the only high back booster that reclines without taking the seat out of the car (except ones tht are from nine months with harnesses. It also has an aluminium frame so alot sturdier and you can move the actual seat base forward as you childs legs get longer. Its great a bit pricey but you can't put a price on safety and it will last for years. You can also wash the covers and it separates into two parts but because of an alumninium bar at back (for recline) you can't use it as a separate booster seat.

One more point if your car sometimes has problems with buckle crunch it sits high enough that I don't have it.
