The Knox is priced at the higher end of the market without corresponding enhancements in convenience or functionality.


Features like integrated Koroyd technology and Side Impact Pods offer advanced safety beyond standard requirements.


While the chest clip's one-button release and the machine-washable fabric are nice, they don't set the Knox apart in a crowded market.


Installation challenges are frequently noted, which could be a significant deterrent for parents who need to move the seat between vehicles.


The machine-washable fabric is a convenient feature, allowing for easier maintenance and cleanliness.


Its premium build comes with added bulk, making it less suitable for smaller vehicles or those needing to fit multiple seats.

Product Overview

The UPPAbaby Knox Car Seat

The Uppababy Knox is a convertible car seat designed for children from birth up to 65 pounds. It can be used both rear-facing and forward-facing. Made by the popular Uppababy brand known for their stylish strollers, the Knox has a sleek, high-end aesthetic using premium materials. However, it does come with some notable drawbacks compared to cheaper alternatives according to customer reviews.

Key Features

What features set this car seat apart from others?

  • Integrated Koroyd technology in the base is designed to absorb crash impact forces. Additionally, 'Side Impact Pods' work to absorb and deflect crash forces during a side impact.
  • The chest clip is a simple one-button release.
  • Machine-washable fabric makes cleaning simpler.
  • A tightness indicator (that turns from red to green) provides visual confirmation the seat is properly installed.

What Real Owners Think

Here's what actual owners of the UPPAbaby Knox had to say based on hundreds to thousands of reviews we've analyzed from Amazon.

Pros Cons
  • Very nice, high-end aesthetics and materials. Parents remark that it is a "very beautiful car seat".
  • Car seat feels very sturdy and durable. It is heavy duty!
  • Chest clip is a button and not a two finger clasp like in other child seats, making it easier to use.
  • This car seat is too large and heavy for many vehicles. This makes it difficult to move between cars. In smaller cars, parents remark that it sits so high they have trouble getting their children into the car seat without hitting their head on the car frame.
  • Many parents seemed to struggle with the installation of this car seat.

Who Should Buy the UPPAbaby Knox?

The Knox's premium styling and materials make it a good choice for parents who want a luxury car seat and appreciate the Uppababy brand. Its high-end look is complemented by a range of safety features, making it a great choice for those who want both style and substance.

However, the difficult installation and fit issues may make it better suited to larger vehicles. Parents who frequently switch between rear and forward-facing will benefit from the convertible design.

Final Verdict

The Knox stands out for its high-end aesthetics, but falls short in ease of use. Shoppers should carefully compare the Knox to cheaper alternatives that offer similar safety and more convenience. For parents who prioritize style and luxury, don't mind the large size, and have a larger vehicle, the Knox absolutely delivers on looks and premium feel.

But for most families, more affordable and easier to use options exist. The difficult installation and lack of adjustability are significant practical limitations.
