Our Thoughts

As a parent, I understand the importance of choosing a car seat that guarantees the safety of your little one during trips short or long. Two options I highly recommend are the Britax Boulevard ClickTight and the UPPAbaby Knox. Both are convertible and switch from rear-facing to forward-facing as your child grows.

The Britax Boulevard is highly praised for its safety and comfort features, solidified by its superior safety ratings. Its ClickTight system simplifies the installation process, ensuring a secure and hassle-free fit in your vehicle. Adjustable recline and harness allow for comfortable seating, even during long rides. It can support children in rear-facing mode up to 40 lbs and forward-facing up to 65 lbs. While some parents comment on its bulkiness and weight, the comfort and security it provides make it a worthy investment. It definitely is ideal for families who prioritize safety and convenience, and do not frequently move the seat between vehicles due to its heaviness.

On the other hand, UPPAbaby Knox is high-end with sleek aesthetics and premium materials. It, too, is equipped with advanced safety features, such as integrated Koroyd technology in the base and Side Impact Pods to absorb and deflect crash forces. Although luxurious, the UPPAbaby Knox is notably challenging to install and is too large for smaller vehicles. It can support up to 45 lbs in rear-facing mode and 65 lbs in forward-facing configuration. Parents who value style as equally important as substance will find it appealing, but its practical limitations may overshadow its aesthetic edge.

Bearing in mind the considerations of safety, convenience, and cost, I recommend the Britax Boulevard ClickTight. It offers great value for money with its versatile use and superior safety features. Its straightforward and secure installation trumps the UPPAbaby Knox, which parents have found challenging to put in place. Although the Britax Boulevard is a bit pricey and bulky, the peace of mind it affords with its safety features and ease of use is worth the investment. However, for those who wouldn't mind spending a bit more for style and can patiently troubleshoot installation issues, the UPPAbaby Knox might be an option too.
