The Knox is UPPAbaby's first convertible car seat that grows with your child through toddlerhood and beyond, from 14 to 65 pounds or 49" in height.

The UPPAbaby Knox includes unique safety features not seen on other convertible car seats, like a multi-directional tether and Koroyd crash-protection technology developed from aerospace safety research.

The tether strap, used for both rear-facing and forward-facing installations, acts like a load leg, anchoring the seat to prevent it from rotating in a collision and causing injury to the child's head and neck. In rear-facing mode, the tether reduced the risk of injury by 45 percent in crash tests.

The base of the UPPAbaby Knox includes Koroyd technology, seen in sporting goods and high-performance helmets, which crumples instantly on impact to absorb energy and slow forces in a crash.

Throughout the core and headrest of the seat, the UPPAbaby Knox is fully lined with EPP, the toughest type of foam. Side impact pods on the sides of the seat serve as the first line of defense in a crash, helping to disperse forces away from your child.

It's easy to tell if the UPPAbaby Knox is installed correctly, thanks to the SmartSecure tightness indicator and a recline indicator that shows safe positions for rear-facing and forward-facing. Features like multiple recline positions and a no-rethread harness add convenience to your daily outings.

The Jordan Charcoal Melange color of the Knox is made with merino wool, a fiber that is breathable, hypoallergenic and naturally fire-resistant.

Have 2 of the Knox!

We love this stroller. It feels highly safe and well made. It has substantial side protection (as noted by the car seat/policeman who installed) if you have your children sitting on the side. They are heavy so not great for travel; but ideal if you're keeping this in your car as your full time car seat.

Great Fit

We purchased this car seat in hopes of finding something better fitting for a 2-door F250. This fits great! We are in rear facing and it sits nearby upright which allows for ample front seat space. It does have a lot of side cushioning which can make getting a child in and out a challenge but it makes me feel like it’s safer and more comfortable that way. The fabric is a great quality and the padding on the straps does not come off so there isn’t a worry about our child removing it. The install was not difficult, just watch the video. Definitely purchasing a second one.
