Meet the car seat designed for your digitally connected life: the Evenflo® All4One™ 4-in-1 Car Seat with SensorSafe™. Featuring integrated SensorSafe technology to keep you connected to your child from the backseat in real-time, the All4One is clearly the savvy choice. And it’s also the versatile choice, because you can invest once in a car seat that will grow with your child for 10 years! That decade of use will take you from rear-facing harness to forward-facing harness and from high-back booster to no-back booster as your child grows from 4 to 120 lb. The innovative EasyClick™ LATCH system easily ratchets to achieve a rock-solid installation 3x* tighter than the competition that can be correctly secured in seconds — without having to get in the vehicle. The All4One headrest lets you choose from 12 positions, and a no-rethread harness allows adjustment with just one hand — no need to uninstall the car seat to get the job done. The All4One is also equipped with SensorSafe to send real-time messages to your phone, alerting you to potentially unsafe conditions in the car, including unexpected chest clip unbuckling, unsafe temperature, child unattended in the car, and child seated too long. So when your eyes are on the road, you can keep that vital parent/child connection. The All4One features side-impact technology which helps absorb energy in the event of a collision. The plush head pillow is designed to properly support your child’s head, and the head and body padding is removable for easy cleaning. Shoulder belt guides properly position the vehicle belt over your child’s shoulder to ensure an accurate fit in booster mode. For added convenience, dual-integrated cup holders keep drinks within your child’s reach. Connect with the All4One. It’s everything you need in one car seat!
