Britax One4Life ClickTight All-In-One Car Seat Review

Jump to Section

If you're looking for a car seat that can accommodate your child as they grow, it's time to turn your attention to the Britax One4Life ClickTight All-in-One Car Seat. Parents get ready because this product is the one-then-done car seat you've been looking for. While there are a number of “all-in-one” car seats available, the hard part is finding a car seat that will give your child a safe and proper fit through ALL stages of use.

Let’s go through the stages of use one at a time, to really break down HOW and WHEN this seat will be used.

Video Review

The Stages

Stage 1: Rear-Facing

The Britax One4Life starts rear-facing and can be used from birth [5 lbs] until 50 lbs or 49” – whichever comes first. The standard rear-facing weight limits on convertible car seats these days ranges from 40-50 lbs*, so we’re excited to see that the One4Life is maxing it out! Just like the Britax convertible seats on the market, the One4Life comes with an anti-rebound bar that decreases forward rotation and aids in stabilizing the car seat in case of a collision.

NOTE: the anti-rebound bar must always be used when installed rear-facing 

Stage 2: Forward-Facing

The One4Life can be used forward facing with the 5-point harness once your child reaches 22 lbs [we recommend not forward-facing a child younger than 2 years old], until 65 lbs or 49” – whichever comes first. 65 lbs is the standard weight limit for forward-facing 5-point harnessed car seats in Canada.

Stage 3: Booster Mode

The One4Life can be used in booster mode once your child reaches 40 lbs or 44”, until they are 120 lbs or 63” . 
We recommend not moving to a booster seat until AT LEAST 4 years old – read more on Booster Seat readiness HERE.

Booster mode is often the most difficult one to achieve in all-in-one car seats because there are certain criteria that have to be met to have a safe & proper seat belt position on your child. The shoulder belt has to center the child’s collarbone and the lap belt has to sit flat over the top of the child’s thighs/low on their hips. The fact that the One4Life has a height-adjustable shoulder belt guide makes a proper fit easier to achieve for your “little big kid”.

Britax Safety Features

As a parent, sometimes the little things in life become the big things. Britax has gone ahead and thought of everything to make life easier with the One4Life, starting with their patented ClickTight Installation system [learn more about that HERE]. They’ve stepped up even further and made it easier to access the system we know and love with a “pinch to access” vs. the “twist to access” like on the ClickTight convertible car seats.

A car seat can’t do its job if it isn’t properly installed every single time, and the ClickTight system gives parents the confidence that their child is protected each time they get behind the wheel.
  • High strength steel frame lines the car seat for superior holdup in case of a collision 
  • Crumple zone slows and helps absorb crash energy into the seat and away from the child
  • Patented v-shaped tether with rip stitching slows crash momentum 
  • 2 layers of side impact protection made of EPP foam line the child’s most vulnerable parts of the body – the head, neck & torso
  • Anti-rebound bar reduces rotation in case of a collision when in rear-facing mode

Additional Convenience Features We Love

  • 15-position no-rethread harness means you can adjust on the fly as your child grows so that you have a proper height even after an overnight growth spurt!
    [reminder that shoulder straps come from below your child’s shoulders when rear-facing and above your child’s shoulders when forward-facing] 

  • 9-position quick-adjust recline allows this seat to fit a wide variety of children and vehicle seat slope combinations.

  • Stay Put” harness pads won’t fall down and interfere with proper chest clip positioning.

  • Clean Comfort fabrics offer stain-resistant & sweat-wicking Nanotex technology on the seat for a clean + cool ride for your babe

  • Extra padding in the seat keeps your child comfortable on even the longest road trips

  • Machine washable fabrics!

  • Woohoo! Tag-free headrest… You may not have thought of this before, but some car seats have labels on the inside of the headrest that can be irritating to sensitive kiddos – no need to worry about that here!

  • Dishwasher safe cupholders included on either side of the car seat for storing drinks, snack cups & favourite stuffies while on the road

  • The crotch buckle flips forward & stays forward, so you don’t have to dig it out from underneath a sleeping or wrestling babe when loading them in
