When it comes to infant car seats, safety is the number one priority for parents. Two features that have gained traction in premium models are load legs and anti-rebound bars—both designed to enhance crash protection. When shopping for your baby, it’s important to understand why these features matter and which infant car seats offer both. While many seats on the market include a load leg or an anti-rebound bar, only a few combine the two. Each feature on its own provides added safety, but together, they offer the highest level of protection—an investment worth considering if it fits your budget.
Why Load Legs and Anti-Rebound Bars Matter
A load leg is an adjustable support that extends from the base of the car seat to the floor of your vehicle. In a crash, it significantly reduces the seat’s forward motion and minimizes head and neck movement, decreasing the risk of serious injury.
Studies have shown that car seats with a load leg can reduce crash forces by up to 46%, especially in frontal and side collisions. It’s a feature that provides greater stability and absorbs energy before it can impact the child.
Anti-Rebound Bar
An anti-rebound bar prevents the car seat from rotating toward the back of the vehicle after a collision—a motion called rebound. This bar adds a secondary layer of protection by absorbing impact and maintaining the seat’s position, keeping the child more securely restrained.
Combined, these two features form a powerful safety duo, reducing both forward and rebound motion in crashes and increasing peace of mind for parents.
