An anti-rebound bar will catch the carseat as it’s rotating into the back of the vehicle seat and help stabilize motion caused by a side impact (if there’s one), dissipating the rest of the energy that’s left. Is it a must-have feature?

A Load leg is an energy management feature that limits downward rotation toward the front of the vehicle. Eliminating the downward rotation by using a load leg means the child stays down in the seat, instead of sliding up, and there’s less potential for injury.
