The Britax One4Life All-in-One Car Seat (5-120lbs) is designed to grow with your child from birth through big-kid booster years. This long-lasting seat transitions from a rear-facing infant car seat to a forward-facing 5-point harness and finally to a high-back belt-positioning booster, delivering up to 10 years of trusted Britax safety in one seat.

Installation is simple with ClickTight®, which works just like buckling a seat belt for a secure, confident setup every time. The SafeWash™ machine-washable cover, high-strength steel frame, SafeCell® crumple zone, and V-shaped tether all work together to help manage crash forces and keep your child protected. Comfort features like multiple recline positions and a quick-adjust harness make One4Life a reliable, hassle-free choice for every stage.

Recommendation – Britax strongly recommends:

  • Children ride rear-facing to the highest weight or height specified
  • Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed
  • The top tether be used at ALL times when installing the child restraint forward-facing.

Good quality good price.
At under $10/qt for high quality marine full synthetic, this is one of the best deals on Amazon. Other marine oils are upwards of $20/qt where I live and having twin outboards that require a total of 8.5qts each every change, that is a real savings. The other great thing about this oil is it’s packaging. The shape of the container and the pull out spout make it easy to pour. I don’t need to use a funnel with these and I didn’t spill a drop.
