Next Level Features

You’ll embrace how easy it is to get your child in and out of the seat. Our Out-of-the-Way spring assist harness system keeps straps propped up, which means no more tangled toddler arms. With the ClipQuik™ one-hand, magnetic chest clip, buckling in and out is struggle-free.

Superior Safety

GCell® side impact protection is built into the headrest to cushion the impact and protect your child around the head. The QuickFit shoulder harness automatically raises the harness and headrest height to fit your growing child.

How do I clean my car seat?

In an effort to save you time and effort, Maxi-Cosi fabrics are all machine washable and dryer safe. Wipe plastic, vinyl, and metal parts with a damp sponge or cloth. The harness system should be cleaned with mild soap and water. Wipe the outside of the buckle with a damp cloth. Do not lubricate the buckle or immerse in water. Do not use bleach or harsh chemicals on your car seat and do not dry clean. Use of cleaning agents such as these can damage your car seat and cause deterioration of the materials.
