Safety you can see
Our unique technology, utilizing a tightness indicator and robust tensioning clips, provides visual confirmation of a correct install, not to mention peace of mind.
The ultimate damage control system
Koroyd® was developed from aerospace safety research, innovated for action sports, now built-in to the base of the KNOX car seat providing more advanced impact protection.
Koroyd’s 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 impact. When used in rear-facing mode, the Multi-Directional Tether reduces potential injury by 45%.*
*2020 results from crash testing conducted at independent labs in U.S. and Canada.
Adjust with ease
Our no-rethread harness, eight-position headrest, and four-position recline all adjust quickly and easily as your child grows.
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.
Protection that’s heads 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.
A small feature that makes a big difference
Positioned on the side of shell and always engaged, the Side Impact Pods absorb and deflect crash forces during a side impact crash.
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.
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 keeps kids cool on hot days and warm on cool days.
