The Britax Advocate ClickTight and Britax Boulevard ClickTight are two of Britax’s newest convertible offerings in general, and two of the first in particular to feature their easy installation ClickTight system. Despite having had the opportunity to review a long list of car seats over the years, I’m always fond of certain companies that demonstrate a commitment to pushing the limits with car seats, and Britax is certainly one of them. The ClickTight seats are designed to make car seat installations with seat belts a foolproof procedure, and I’d say they’re just about there. However, given the similarities of the Advocate and Boulevard, it’s not easy for a layperson to tell them apart. Here’s a straightforward comparison of the Advocate ClickTight and Boulevard ClickTight to help you figure out which is the better seat for you. If you don’t have time to read the whole review, my suggestion is to go with the Advocate ClickTight. If you’ve got time, settle down and get comfortable. Here’s my full review of the Advocate ClickTight, and here’s my full review of the Boulevard ClickTight.

The truth of the matter is that you can’t really go wrong with either seat, and if you were to blindly pick one or the other, you’d still have your child set up in one of the best convertible car seats you can currently buy in the United States. Neither will allow you to rear-face to the heaviest limits currently available in the US, which is the 50 pound limit reached by the Fllo, Foonf, Rainier, and Pacifica, but both seats will definitely put you on the path toward a safe and secure installation, which is a huge part of car seat safety. That said, just because both seats are great doesn’t mean one isn’t going to be a better fit for one family vs. another, which is why I’ve got this guide set up.

Here are reasons to choose the Advocate ClickTight over the Boulevard ClickTight.

1. You want Side Impact Cushion Technology, or SICT. This is the biggest structural difference between the Advocate ClickTight and Boulevard ClickTight. Rather than having SICT, the Boulevard ClickTight includes True Impact Side Protection. What does this mean?

The SICT is Britax’s terminology for a shell designed to absorb crash forces and keep children safe from debris and intrusion, an energy-absorbing head support system to reduce forces on the head and neck, and external cushions that are designed to compress to reduce crash forces before they reach children while simultaneously protecting nearby passengers from injury. This comes with the Advocate ClickTight. The Boulevard ClickTight, on the other hand, includes the energy-absorbing shell and headrest, but does not include the external cushions. If you want them, go for the Advocate ClickTight.

2. You don’t need maximum room for 3 across installations. The Advocate ClickTight is 20.5 inches in width while the Boulevard ClickTight is 18.5 inches wide. These two inches can make a significant difference in your ability to achieve a successful 3 across installation if you’ve got a smaller car, although they won’t make much of a difference in a larger vehicle. If you’ve got space constraints and are trying to achieve a 3 across installation, you might want to look at the Boulevard ClickTight over the Advocate ClickTight. Either way, check the 3 across guide to car seat installations to see what’s typically possible in your vehicle or a vehicle of your size class.

3. You can afford the price difference. I don’t typically suggest making decisions on car seats exclusively on price, but if you’re really stuck between the two, keep in mind that one costs around $50 more than the other. If you’ve got the extra cash, the Advocate ClickTight is the top of the line convertible from Britax right now. If you don’t, the Boulevard will get you 95% of the way there for a bit less.

If you can satisfy these conditions, or even if you can’t and simply want it because you feel it’s the best fit for your family, then the Britax Advocate ClickTight is your seat. If not, then you’ll get nearly the same performance from the Boulevard ClickTight. You can buy the Advocate ClickTight here and buy the Boulevard ClickTight here.
