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.

Protected by Koroyd

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 providing more advanced impact protection.

Koroyd

Koroyd’s welded tubes crumple instantly and consistently on impact, absorbing maximum force in a controlled manner, minimizing energy transferred to the child.

The KNOX tether helps keep the seat secure

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.

Included removable cup holder

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.

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

The KNOX headrest can be adjusted to your child

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.
