Britax Grow With You ClickTight+ Harness-2-Booster Seat

Allow for 2 week shipping time.

Choose a toddler car seat that grows with your child from toddler to big kid age with the Britax Grow With You(TM) ClickTight(R) Plus harness-2-booster car seat. This high back booster seat starts as a 5-point harness car seat and converts into a belt-positioning booster that works with your car's seat belt. Install with confidence, every time. With ClickTight Technology, you know it’s right in 3 easy steps: open, buckle and close.

Features we love:
Quickly adjust the 9-position harness and headrest using just one hand for the proper fit as your child grows. Once they’re ready to use the seat belt, the 5-point harness tucks away, transitioning the seat to a belt-positioning booster. The color-coded belt guide helps you and your child route the seat belt through the right paths for a secure fit. This forward facing car seat is made with a SafeWash(R) cover that's soft to the touch and safe to machine wash and dry, and a knit construction that’s naturally flame retardant. SafeCell(R) Technology in the base acts as a crumple zone to help absorb crash energy for additional protection for your growing child. This booster features an impact-absorbing external cushion, armrests, 2 cup holders and stay-put harness pads, so even big kids enjoy the ride.

Recommendation – Britax strongly recommends that children should be secured with a harness system until they exceed the weight or height limits specified

SafeCells in the car seat base create a crumple zone that absorbs crash energy to help keep it away from your child.
Industrial Strength Steel frame reinforces the seat structure to help keep it stabilized.
V-shaped tether with staged-release stitches helps slow and reduce forward movement during a crash.
Energy-absorbing shell and foam-lined headrest surround the head, neck and torso.
Nap-Friendly Padding & Fabrics-For superior comfort and a quiet ride
Easy-to-remove cover for cleaning without uninstalling the car seat or removing the harness.
Four Cup and Snack Holders-Keep drinks, snacks, and toys within reach

About Britax
At Britax, we believe family life should be lived without limit. A world where parents and children are free to make the most of every moment together. And we think it's our responsibility to make this happen. By driving safety standards to ensure children have never been better protected on the move. By pushing boundaries in smart design to make life in motion run smoothly. By extending a helping hand – or two – and always celebrating the journey.

We've been leading the way in child safety technology for more than 70 years. Always innovating, always focusing on what's best for the child, always going beyond 'good enough'. From Europe's best-selling car seat brand, we've become one of the brands most trusted by American families since we launched here in 1996.

Since then, we've revolutionized side impact protection, transformed safe seat installation, and introduced a range of smart strollers designed around the changing needs of today's families.

Our ongoing, open-ended conversation with parents is complemented by our work with car manufacturers, government bodies, and child passenger safety experts – collaborating, advising and using our industry-leading testing facilities to continually find ways to give parents the products and the reassurance to live family life without limit.

Because we believe in helping every parent and every child find their family freedom.
