Our Thoughts

The Graco Extend2Fit and the UPPAbaby Knox are both convertible car seats that cater to various stages of a child's growth, providing value over time. They can be used in rear and forward-facing configurations, adhering to safety advocates' recommendation that children ride rear-facing as long as possible.

The Graco Extend2Fit shines in terms of value and adaptability. It serves a broader weight range, allowing rear-facing till 50 lbs compared to the Knox's 45, translating to a longer rear-facing period for your child. Moreover, the Extend2Fit grows with your child, transitioning from a rear-facing harness from 4-50 lbs to a forward-facing harness for 22-65 lbs kids and finally a high-back booster for children between 40-100 lbs. This isn't possible with the Knox, which lacks a booster mode. Thanks to the 4-position extended panel, the Extend2Fit also provides upto 5 inches of additional legroom, enhancing the comfort for your child.

However, where the Graco Extend2Fit stumbles, the UPPAbaby Knox takes lead. For instance, the Extend2Fit falls short in terms of ease of cleaning. The seat cover is tricky to remove and the hooks associated are not easily accessible. On the other hand, the Knox possesses a machine washable cover, making the cleaning process significantly easier.

Digging deeper into safety features, both the seats offer beyond standard requirements. The Extend2Fit comes with a reinforced steel frame, ensuring durability and strength while the UPPAbaby Knox uses integrated Koroyd technology in its base, designed to absorb crash impact forces, adding an extra layer of safety.

However, both come with setbacks. Extend2Fit parents reported difficulty in tightening the harness, while the frequent complaints about the size and weight of the Knox showed it can be too bulky, especially for smaller cars. The Knox also lost some points because of the difficulties faced while installing it.

In conclusion, if you're looking for a long-term investment that grows with your child, is budget friendly, and has a higher rear-facing weight limit, the Graco Extend2Fit would be a reliable option notwithstanding its cleaning difficulty. The UPPAbaby Knox, although more aesthetically pleasing and easier to clean, comes with a heftier price tag and the lack of a booster mode, therefore may not provide the same level of value as the Graco Extend2Fit.
