With ClickTight installation and a slim design, this seat transforms from rear-facing to forward-facing and booster mode, keeping your child secure and comfortable for 10 years.
• All-in-One Car Seat: One4Life® Slim is a convertible and harness-2-booster seat in one! It easily converts from a rear-facing infant and toddler seat (5-50 lbs.) to a forward-facing seat (30-65 lbs.) to a high-back booster seat (40-120 lbs.)

• 10 Years of Use: This slim all-in-one car seat grows with your child from 5 to 120 lbs. and up to 63” tall

• ClickTight® Installation: Install with confidence in 3 easy steps: pinch to open, thread and buckle, click it closed!

• SpaceSaver™ Design: Slim outside, spacious inside! The 17.5” seat is designed to fit 3 across without compromising on trusted Britax safety and premium comfort. *Britax cannot guarantee 3-across installation fitment in all vehicles

• Premium Fabrics: The woven mélange accents give the car seat cover a tailored look, while the soft knit fabric on the padding and inserts helps keep your child comfortable during every ride

• Woven Accents on the Exterior and Comfort Pads: Made from recycled polyester

• Hassle-Free Cleanup: Extra space between the shell and base means you can clean under the seat with ease – and with minimal grooves in the seating area and base, you can wipe it down with no fuss

• SafeWash® Fabrics: No more hand-washing or waiting for the cover to air-dry; just quick and easy cleanup so you can keep moving

• Naturally Flame-Retardant Cover: With no added FR chemicals

• Three Removable Infant Inserts: Help provide a better fit for infants 20 lbs. and under

• Accessible Color-Coded Belt Paths: Make it easy to route the seat belt through the correct path for each car seat mode

• Slide-Out Cup Holders: The dishwasher-safe cup holders slide out with ease for convenient cleaning and click back into place for a secure attachment during rides

• Cup-Holder-Free Option: Remove the cup holders completely and insert the armrest caps to save additional space

• 15-Position No-Rethread Harness and Headrest: Adjust together quickly and easily with one hand to help create the proper fit as your child grows; no rethreading, ever!

• Patented V-Shaped Tether with Staged-Release Stitches: Helps slow and reduce forward movement during a crash

• High-Strength Steel Frame: Reinforces the seat structure to help keep it sturdy and stabilized

• Quick-Push, 9-Position Recline with Easy-Read Indicators: Helps you find the most comfortable fit for your child and the correct angle for your vehicle

• SafeCell® Technology: Acts as a crumple zone, absorbing crash energy to help keep it away from your child

• Two Layers of Energy Management: The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe

• Soft Comfort Pads: Help prevent the harness from rubbing against your child’s skin

Love the car seat, brand and color

You can never go wrong with Britax car seats. I really love how it can be used rear facing and toddlers have more leg space than in infant car seats. I loved the color too!
