Description

This Graco car seat is their slimmest design. It fits three car seats across in your back seat (in every configuration), saving space without compromising safety.

The narrow all-in-one design grows with little ones from rear-facing harness (5-40 lbs) to forward-facing harness (26.5-65 lbs) to highback booster (40-100 lbs).

Integrated belt lock-off makes for easy vehicle seat belt installation in forward-facing mode, and allows you to position seats to maximize space with three across.

Graco’s exclusive push-button InRight LATCH provides an easy, one-second attachment with an audible click to help ensure secure installation.

The No-Rethread Simply Safe Adjust Harness System allows you to adjust the height of the headrest and harness to ten positions with just one motion for just the right fit. Adjust the four-position recline for a better installation and a comfortable ride.

The Rapid Remove cover comes off in 60 seconds, without uninstalling the seat or removing the harness, and it’s machine washable.

Breathable mesh AirFlow channels provide improved ventilation to keep kiddos cool and comfortable. Two cup holders are designed to work with the three-across configuration to keep drinks and snacks close at hand.

Fuss-free harness storage pockets conveniently hold the harness out of the way while children get in and out. Removable, plush head and body inserts also keep baby feeling cradled and comfortable.

The steel-reinforced frame provides strength and durability for years of use, and EPS energy-absorbing foam provides effective impact energy management.

For peace of mind, it’s Graco ProtectPlus Engineered. This is a combination of the most rigorous crash tests that helps to protect passengers in frontal, side, rear and rollover crashes.

Works great!

It sits more upright than the infant seat we were replacing, so watch the angle if your little one naps in the car to help keep them comfy.

Really liked this and glad there is an option to get three car seats in the back of our Chevy equinox. Baby on the way and trying to find the best fit for the twins as well.

Installation is easy, and i love how simple cleaning is as well. Everything buttons on, but securely, so when messes happen all the fabric can just be tossed in the wash
