Our Thoughts

Taking a detailed look at the Chicco NextFit Zip and UPPAbaby Knox, both of them are convertible car seats built to cater to your child's safety and comfort needs as they grow; however, they each embody their unique strengths and areas of improvement.

The Chicco NextFit Zip distinguishes itself with its emphasis on security and durability, easily justifying the financial investment by offering prolonged use in both rear-facing and forward-facing modes. Parents have praised this car seat for its safety attributes, represented by its high sides, and a robust structure that imbues confidence. It excels in practicality, primarily through its SuperCinch LATCH tightener ensuring secure installation, and its Zip & Wash seat pad that simplifies upkeep and sanitization. However, be aware that the seat's solid build may limit front passenger legroom and make the seat less portable for vehicle transfers. Also worth noting is that while it comfortably accommodates children up to 65 pounds in the forward-facing mode, the rear-facing limit caps at 40 pounds, which might make it a bit restrictive as children grow.

Shifting the spotlight to the UPPAbaby Knox, it gives off a high-end aesthetic vibe and includes notable safety features. Even if the Knox is at the higher price range, features like integrated Koroyd technology and Side Impact Pods push it beyond standard safety requirements. The Knox shows its practical side with a one-button release chest clip and machine-washable fabric. However, it appears to lag behind the NextFit Zip in user convenience, with a notable number of parents experiencing challenges in installation and finding it a bit of a challenge to fit this seat into smaller cars. Despite this, its capability to accommodate up to 45 pounds in the rear-facing mode, a 5 pound increase compared to the NextFit Zip, is worth noticing.

In comparing between the two, the Chicco NextFit Zip stands out for its easy maintenance and streamlined installation process while the UPPAbaby Knox showcases a solid construction embodying elegance and promises advanced safety features. If your priority leans towards convenience, ease of maintenance, and simpler installation, the Chicco NextFit Zip is the obvious recommendation. It hosts a plethora of beneficial features and gives value for money. However, if you have a larger vehicle and are aiming for a more luxury car seat with advanced safety measures, and the added weight is less of an issue, then the UPPAbaby Knox could be well-suited for you.
