About the Britax Boulevard 70 CS

 In the realm of baby bests, the name Britax is practically synonymous with car seat. The Britax Boulevard 70 CS is one of the top of the line convertible car seats from the Britax product line — the best of the best. And fittingly, it is comfortable, effective and easy to use. The Britax Boulevard 70 CS accommodates infants from 5 to 40 pounds in the rear-facing position, and children at least 1 year old and 20 to 70 pounds in the forward-facing position. This allows you to invest in a car seat just once from birth to booster. Really!


The Britax Boulevard 70 CS utlizes the Britax Click & Safe™ harness indicator, which features an audible click. That click alerts you when the harness straps are in position. Once your little traveler is in the seat, you will click-click-click the harness safely into place. This helps to prevent risks associated with misusing a car seat. As a parent, you strive to get the safest, most comfortable seat for your child. The Boulevard 70 CS is just that.


The Britax Boulevard 70 CS has a superb silhouette, giving kids support where they need it, but without unnecessarily restricting movement. The deep, side wings of the reinforced headrest are lined with energy-absorbing EPP foam and offer True Side Impact Protection™, providing a comfy, stable ride devoid of slumping heads. The deep side walls of the Britax Boulevard 70 also provide side-impact protection around the child's body.


The Boulevard 70 CS offers an easy-adjust knob that enables you to adjust the shoulder straps of the 5-point harness without uninstalling hte car seat. So, whether your child has had a growth spurt, or is bundled in a bulky parka for winter, you can easily adjust for fit. Similarly, the plush fabric cover can also be removed without uninstalling the car seat, so it's easy to clean the fabric when you need to.
