    Product Description

    From baby to big kid, the Continuum All-in-One car seat is there for your family through three different stages from 5-80 pounds.This convertible car seat can be used in the rear-facing position from 5-40 pounds, and includes a comfy grow-with-baby pillow to give a smaller baby a snug fit. The pillow easily removes when no longer needed. Once in forward-facing mode, the Continuum keeps your child safer in the harness up to 50 pounds. When your child is ready to transition to vehicle seat belts, simply remove the harness to use the Continuum 3-in-1 Car Seat in belt-positioning booster mode all the way up to 80 pounds.In both rear-facing and forward-facing mode, harness holders keep the harness in an open position. This makes it easier for you to get your child in and out of the car seat. No more fishing for the harness and clips from behind your child – they’re right there when you need them. The QuickFit™ Harness offers additional convenience in both of these stages by letting you adjust the height of both the headrest and harness in one quick and easy step, making it simple to give your growing child the best fit. In booster mode, the headrest still adjusts easily on its own so that you can continue to get the best fit for your child.The Continuum is simple to clean with a machine washable and dryer safe cover that removes easily from the seat. The pad attaches to the seat with snaps so there’s no need to remove the harness or disassemble the car seat. Just unsnap and lift the pad away to put it in the machine. The cup holder is also designed to be easy to clean. Just twist it out and put it into the dishwasher to get rid of the goopy buildup that ends up in every kid’s cup holder.The Continuum is designed to provide more comfort to you and your other adult passengers too. It takes up less room when placed rear-facing, giving up to 7 inches more leg room for grownups in the front seat.

    Why Grow and Go?Kids grow so fast that it seems to happen overnight. (These jammies fit yesterday!) The Grow and Go is a All-in-One convertible car seat that’s ready to take baby home from the hospital or bring a big kid to soccer practice – and it’s there for you every wonderful moment in between. Let’s face it, life as a mom can be hectic, but with the Grow and Go it’s easy for them to grow and for you to be on the go.Ready for Any Bumps in the RoadCrashes aren’t something you’d like to think about, but don't worry, we’ve been making car seats for 30 years, so together, we've got this.Cleaning your car seat can be challenging! Big kids sneak in snacks and you find them mushed into every crevice. And little kids can turn tiny sips into giant puddles. But the Grow and Go is easier than ever to keep clean. The seat pad comes off and goes straight in the wash, without removing the harness – because you don’t have time for that.Ever try and get a kid who is arching their back in a car seat? No, well chances are it will happen at least once, because no one likes leaving the park. Harness holders make it easy to get “Archie” and “Floppy” into the seat.For those times when you have to move the car seat from one car to another, we have you covered, too. Installing the Grow and Go doesn’t require a PHD, but if you need help, we have lots of videos on YouTube for that!
