Peace of Mind with the Safest and Easiest Installation - Typically up to 75 percent of car seats are installed incorrectly, but our revolutionary ClickTight Installation System is the safest and easiest technology on the market. Just open the front of the car seat, buckle the seat belt across and click the seat shut. That’s all you need to do for rock-solid installation – the seat won’t budge and you can travel worry-free with your child.  

SafeCell Impact Protection: The Best Protection, Only from Britax - Britax is the only child car seat brand that features world-class SafeCell Impact Protection. This integrated system of safety components provides unmatched protection for your child. These features include a steel frame, energy-absorbing base, V-shaped tether to minimize seat rotation and staged-release stitches that slow and reduce forward movement during a crash.  

Layers of Side Impact Protection - Side impacts represent 25 percent of collisions and result in the most severe injuries. We designed the Advocate ClickTight with these statistics in mind. The seat has a deep foam-lined shell, quick-adjust head protection and side cushions, forming 3 layers of side protection – the best protection for your child.

Smart Design - Almost 60 percent of car seat harnesses are too loose. Britax’s patented Click & Safe Snug Harness Indicator takes the guesswork out of seating your little one and lets you know that your child’s harness is within range of proper tightness with a click sound.

Maximum Fit and Comfort - We developed the Advocate ClickTight to safely and comfortably hold your child from birth all the way through the preschool years. The easy-adjust harness grows along with your child with 14 different positions. Change the height of the seat with just the push of a button – no inconvenient rethreading necessary.
