Safety, comfort, and innovation come together in the Defender MAX SIP, a next-generation car seat designed to give parents peace of mind and children a secure, comfortable ride. Engineered for longevity, it grows with your child from a forward-facing harnessed seat to a high-back booster and finally to a backless booster—providing years of reliable protection.

As one of the first car seats to meet the new U.S. side-impact safety standards, the Defender MAX SIP sets a new benchmark in child passenger safety. Its full-body impact protection, anti-torque backrest and headrest, and energy-absorbing EPE foam work together to minimize crash forces, ensuring your child is surrounded by top-tier protection at every stage.
