$ 349.99 USD


If you’re looking for a fantastic combination of adaptability and safety in a car seat, you’ve come to the right place! We’re so happy to introduce you to the UPPAbaby Knox, which boasts both top-of-the-line safety features and the ability to accommodate both rear-facing and forward-facing seating options, a first for UPPAbaby. Some of the amazing elements of this top-tier car seat include:

  • Advanced seat security: Safety is the name of the game when it comes to the UPPAbaby Knox. Outfitted with security features such as the SMART Secure locking system (for fastening your car seat firmly in place), a multi-directional tether (for keeping your car seat from moving forward during a collision), an active support headrest (for protecting your child’s head from any crash forces), and SMART Side Impact Protection pods (for redirecting any energy from a collision away from your child), your kiddo will be protected on all sides while sitting in the UPPAbaby Knox. The UPPAbaby Knox is made with high quality EPP impact absorbing foam and also has an innovative Koroyd crumple zone built into the base that absorbs maximum forces to minimize the energy transferred to your child.
  • Seat installation indicator: Worried that you didn’t install your car seat correctly? With the UPPAbaby Knox’s seat installation indicator, you can kiss those worries goodbye! This handy, built-in indicator gives you visual confirmation that your car seat is secure in your car.
  • No-rethread harness that grows with your child: The UPPAbaby Knox’s adaptability doesn’t end with its ability to accommodate both rear-facing and forward-facing seating options! The Knox’s no-rethread harness enables you to adjust your child’s harness straps as they grow, keeping them safe throughout every stage of their infancy and toddlerhood. The seat's two-piece inlay also allows you to adjust the seat as your little one grows.
  • Variety of color options: From classy charcoal to totally fun teal, the UPPAbaby Knox is available in a number of different color options, including Jordan (fire-resistant Merino wool in charcoal mélange), Bryce (white and grey marl), Jake (black mélange), and Lucca (teal mélange).

The UPPAbaby Knox is safe to use with children who are over 14 lbs of weight. It can safely hold a child up to 40 lbs in the rear-facing position and up to 65 lbs in forward-facing position.
