Uppababy Knox FAQs

What is the difference between this version of the Uppababy Knox and the 2019 version?

In 2021, Uppababy brought the new KNOX to the marketplace with features that enhance ease of use and fit in vehicle:

  • Recline Indicator – Labeling system provides greater instructional detail on acceptable seat positions in rear-facing and forward-facing mode.
  • Two-Piece Fit Inlay – Inlay allows for flexibility and proper fit in the harness system.
  • Wider Base – Increased in size to help with vehicle install and compatibility.

What options for installation does the Uppababy Knox have?

You can use LATCH in rear-facing mode until a child is 35 lbs. After the child reaches 35 lbs, it’s time to switch to belt installation.

For forward-facing installations, we recommend using belt only as remembering to switch from LATCH to belt is simply one more thing parents could forget.

Is LATCH safer than seatbelt as an installation method?

Both systems are tested to the same rigorous crash testing and meet government safety standards. Installation method depends on what is best for you and your vehicle.

Which position is best for my child to use the Uppababy KNOX?

  • Suitable for approximately 1–6 years old*
  • Rear-facing: from 14–45 lbs, and using the included fit inlay from 14–25 lbs to achieve a proper harness fit.
  • Forward-facing: from 25–65 lbs Height: up to 49″

In both rear-facing and forward-facing mode, the headrest should be positioned at the child’s shoulders to ensure proper fit of the harness. The headrest can lightly touch the shoulders and allow at most a fingertip of space between the child’s shoulders and headrest.

*Knox is not suitable for newborns, as the starting weight will be 14lbs

What color of the Uppababy Knox is free of fire-retardant chemicals?

The high-grade Merino wool blend bonded to foam makes the JORDAN KNOX a naturally fire-resistant, while also passing federal fire safety testing (FMVSS302) without the application of chemical flame retardants and without brominated and chlorinated chemicals.

Can you wash the fabric of the Uppababy Knox?

Yes, you can machine wash the KNOX seat fabric and fit inlay cover on a gentle cycle. The seat base fabric can be removed for easy cleaning. Lay all fabrics flat to dry. We recommend spot cleaning the upper body fabric whenever possible.

Can I fly with the Uppababy Knox?

KNOX is FAA-approved for use in an airplane.
