As we reported earlier this summer, Britax has launched a new generation of its best-selling seats: the Roundabout, Marathon, Boulevard and Advocate.

Now that the seats have been on the market for about a month, we are ready to issue our recommendation: the new Britax seats will earn our top rating in our next BABY BARGAINS book.

Here’s a quick overview:

  • The seats now have higher weight limits: the Roundabout is 55, Marathon, Boulevard and Advocate are 70. All the seats are now rear-facing to 40 lbs—that is fantastic, as it will help parents keep babies rear-facing longer.
  • The new safety features include deeper side walls for side-impact protection and foam that lines the entire seat. The redesigned shell features new technology (SafeCell) to absorb more energy in a crash.
  • Prices are the same as the old seats: fortunately, Britax isn’t raising prices on the new seats.

Feedback from our readers on the new seats has been positive (although limited, as the seats are still rather new). Feel free to post your comments below or email us.

Overall, these convertible seats will earn our highest rating. From little touches like covers that now easily remove for cleaning to improved belt paths and LATCH attachments, these Britax seats are winners.
