For the most part, yes. High-end safety seat manufacturer Britax is an exception to that rule. Britax recommends using its own specially manufactured car seat protector with the child safety seats the company manufacturers. Britax car seat protectors are designed specially to fit their line of car seats and have been crash-tested to guarantee they are slip-free. In addition, Britax car seats are notoriously large and heavy; these protectors help prevent indentation marks in your vehicle’s seat. Of course, you could always give an off-brand car seat protector a try, but if you’re already shelling out the money for a Britax, you might as well protect your investment.
