It didn’t make it to the Kidz In Motion Conference, but it’s now in production! I evaluated a pre-production model of the Britax Boulevard CS recently and found it to be a very clever feature addition. Basically, the mechanism senses when the tension you put on the harness adjustment strap is meeting resistance from the child. As you give a solid pull, it gives a distinct tactile and audible [double] click when the harness is adjusted to an acceptable point. It’s really that simple.
I am going to wait to make a final opinion until I have a production model, hopefully by the end of the month, but my overall impression was positive. I will say that it is not foolproof. For example, it can be fooled by thick winter coats, just as a parent can be fooled. The manual clearly mentions thick clothing is a concern, as it is in every child restraint. It’s also possible to have the harness tight enough, even though you haven’t yet heard the click (or maybe you released your pull just a bit too soon). Parents, advocates and technicians who are familiar with adjusting a 5-point harness correctly may find this to be mostly a gimmick, though still a pretty cool one. On the other hand, for many parents and caregivers who often leave the harness too loose, I found it to be a very quick and simple way to get a good adjustment of the harness the vast majority of the time. If you pass your seat to a relative, babysitter or daycare, it’s also a simple way to make sure they get it right when you aren’t there!
