Triple safety, triple comfort

The only thing that beats two layers of protection is…. three. Our Tri-Protect™ headrest is engineered for optimal head and neck security. With comfort that keeps your little one snug.


Easily adjust for every growth spurt

Easily adjust the headrest and harness together with just one hand for a safe secure fit when sharing between multiple children or to keep up with those unexpected growth spurts that seem to happen overnight. No removal and reinstallation required.

From birth to big kid

The i-Quest can be the only car seat you need from birth to approx. age 4 when paired with the i-Base™ lx 2. Or use it with the same base after the i-Level Recline carrier.
