Easily adaptable Convertible Car Seat packed with intuitive safety features


Stay Safe. Keep Going.™

From baby to big kid, the KNOX Convertible Car Seat is packed with intuitive safety features and easily adapts as children grow and their positioning needs change.



SMARTSECURE® System for Easy Installation
Energy Response Technology for Unparalleled Side Impact Protection
No-Rethread Harness, Eight-Position Headrest, and Four-Position Recline
Active Support Headrest with Specialized Foams for Added Absorption


Safety You Can See
Our unique technology, utilizing a tightness indicator and robust tension clips, provides a visual guide to aid in achieving a correct installation — not to mention peace of mind.

Adjust With Ease
Our no-rethread harness, eight-position headrest, and four-position recline all adjust quickly and easily as your child grows.

A Chemical-Free Choice
Through its innovative use of Merino wool, the JORDAN KNOX passes federal safety standards without the use of fire-retardant chemicals. The wicking properties of Merino wool keep kids cool on hot days and warm on cool days.


The Ultimate Damage Control System
Koroyd® was developed from aerospace safety research and is now built into the base of the KNOX car seat, providing more advanced impact protection. The welded tubes crumple instantly and consistently on impact, absorbing maximum force in a controlled manner, minimizing energy transferred to the child.

Tether Them Better
The Multi-Directional Tether reduces seat rotation and stress on the child’s head and neck in the event of an impact and is strongly recommended with both rear and forward-facing installations. When used in rear-facing mode, the Multi-Directional Tether can reduce injury potential by 45%.*

Sip And Go
Sippy cup or water bottle, the KNOX includes a removable cup holder that can attach to either side of the seat. When spills happen, the seat base fabric can be removed for easy cleaning.


Energy Response Technology
A family of features designed to protect and provide unparalleled side impact protection.

A Small Feature that Makes a Big Difference
Positioned on the side of the shell and always engaged, the Side Impact Pods absorb and deflect crash forces during a side-impact crash.


Protection That’s a Head Above the Rest
Absorption and recovery properties of specialized foams in the Active Support Headrest provide advanced side impact protection that grows with your child.

Impact Dispersion Zone
Strategic placement of EPP foam between the inner and outer shell ensures forces are absorbed into the seat rather than the child.
