  • 3-IN-1 VERSATILITY WITH AWARD-WINNING SAFETY: The Defender 360 Max grows with your child, transitioning from a 5-point harness (up to 29.5 kg / 65 lbs.) to a high-back booster and then to a backless booster, providing long-term use and exceptional value. Rated an IIHS Best Bet Booster in both booster modes, it ensures superior belt fit and safety as your child grows.
  • 360° FULL‑BODY CRASH PROTECTION: Cushioned by energy‑absorbing EPE foam throughout the headrest, backrest, and base, the seat envelops your child for comprehensive protection in front, side, and rear impacts.
  • SECURE UAS/LATCH INSTALLATION: Equipped with the Universal Anchorage System (UAS/LATCH) and top tether, this seat allows quick, stable, forward-facing installation, ensuring a secure fit every time.
  • PREMIUM COMFORT FEATURES: With an ultra-plush, machine washable seat pad, shoulder and crotch pads, multiple recline positions, and practical cup/snack holder that can be easily installed on either side, long rides become cozy and convenient.
  • EFFORTLESS 1‑HAND ADJUSTMENTS: A 9‑position, no‑rethread harness height adjuster and a 1‑hand, front harness adjuster provide ultra‑smooth, easy customization as your child grows.
  • PROTECTS YOUR CAR, SAVES SPACE: Smooth, contoured V-shaped seat protects your vehicle’s upholstery, saves space, and allows three car seats to fit across in most vehicles, making installation easier even in tight spaces.
  • COMPREHENSIVE STANDARDS: Compliant with NEW USA FMVSS 213 and Canadian CMVSS 213.2 standards and remains safe for use up to 10 years after date of manufacture. Visually pronounced belt guide ensures proper seat belt routing every time.
