Sturdy, Sturdy, Sturdy. What else can I say? The latch system is easy to install and easy to take off. No problems getting it setup in a small or large car. Easy to tighten so that the carseat doesn't move around. All you have to do is pull the straps. Only problem I had was that you can't take it on the plane. It's too heavy so they say you can't take it on.
