UPPAbaby KNOX Convertible Car Seat


UPPAbaby is launching its first convertible car seat, the UPPAbaby KNOX!

Expected to debut in Spring 2020, the KNOX is UPPAbaby's first car seat that grows with your child from rear-facing to forward-facing and from 14 pounds through toddlerhood and beyond.

UPPAbaby does not yet have an exact release date for the KNOX, please sign up for our e-mail list to be notified when the UPPAbaby KNOX is available for pre-order!

In a unique feature, the UPPAbaby KNOX includes a multi-directional tether that can be installed rear-facing. The tether strap acts like a load leg, anchoring the seat to prevent it from rotating in a collision and causing injury to the child's head and neck.

Throughout the core and headrest of the seat, the UPPAbaby KNOX is fully lined with EPP, the toughest type of foam used in motorcycle helmets. Side impact pods on the sides of the seat serve as the first line of defense in a crash, helping to disperse crash forces away from your child. A feature newly added to the KNOX is Koroyd crumple technology - seen in high-performance motorcycle helmets, this material is built into the shell of the KNOX for more sophisticated energy absorption.

The UPPAbaby KNOX is easy to use and install, thanks to features like the SMARTSecure system that provides visual confirmation of a secure installation and a no-rethread harness that adjusts to nine positions when you move the headrest.

The seat reclines to multiple positions in both rear-facing and forward-facing. Silicone patches on the harness pads help keep the harness secure and protect your child's chest.

The UPPAbaby KNOX is expected to be available in 2020 in four colors. The Jordan color comes in merino wool, a natural fiber that is free of flame retardant chemicals and helps to regulate body temperature.

  • Bryce (white and gray marl): $349.99
  • Jake (black melange): $349.99
  • Lucca (teal melange): $349.99
  • Jordan (charcoal melange with merino wool): $389.99 



  • Rear-facing: 14 to 40 pounds
  • Forward-facing: 25 to 65 pounds; up to 49" in height
