The base has an anti-rebound bar (ARB) built into it. The anti-rebound bar is an added safety feature for rear-facing that can reduce the secondary movement of the car seat, called rebound, during a crash. When a collision occurs, the car seat will move forward, towards the front of the vehicle, and rotate downward. And as we all know from high school physics, every action has an equal and opposite reaction — so after that initial movement, the car seat will rebound, or “bounce back” towards the backrest of the vehicle seat. The ARB minimizes this bounce-back effect, helping limit the car seat movement and your child inside it! ARBs may also limit the side-to-side rotation of the car seat in a side-impact collision. Overall, it’s a great feature on a rear-facing car seat!

If you want to install your car seat in the middle and your middle seat does not have lower anchor points, then you will need to do a seat belt installation. The Clicktight mechanism on the base makes getting a solid installation quick and effortless.

This seat can be installed baseless with European or American/Standard belt routing. You can find a video showing both of those methods here. The European routing method is preferred! European belt routing means the shoulder belt portion of the seat belt is routed behind the shell of the rear-facing seat, limiting its ability to rotate down in a frontal crash. This routing functions similarly to a load leg. Pretty cool, huh?!
