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.

• Converts from rear-facing to forward-facing, growing with your child from 14 to 65 pounds

• Koroyd, a welded tube structure in the base of the seat, provides crash impact protection by crumpling on impact to absorb crash forces and reduce acceleration

• EPP foam integrated into side impact pods and along seat shell absorbs forces in a collision

When we received these car seats for our twins, our older daughter, who only uses a booster, also wanted one for herself. We have not installed them yet because the babies are only 4 months old, but they look very comfortable and reliable.

Great car seat

Very happy with all of our Uppababy products. Decided to stick with them as we transitioned from the infant car seat. Easy install with LATCH. Seems easy with seatbelt but can’t confirm. Baby likes it a lot more than the last one.

Excellent

Wow! What a step up for my forward facing big girl. This car seat is so safe, secure, and beautiful. My daughter is so much more comfortable and does longer rides with more ease. Highly recommend this car seat!

Needs improvement

Very difficult to install. Very heavy. I’m a big guy and putting enough pressure on the seat to see green is very difficult. If you are putting this in your car/truck and never removing it, you may be fine.
