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.
