  • CHEMICAL-FREE CHOICE: The Knox features both our SafeTech & PureTech fabrics & foam that are fire retardant chemical free. The Jordan & Gregory fashions, made with Merino Wool, keep kids cool on hot days, warm on cool days.
  • TETHER THEM BETTER: The Multi-Directional Tether reduces seat rotation & stress on the head & neck during an impact & is strongly recommended with rear & forward-facing installations. When rear-facing, the Tether can reduce injury potential by 45%.*

  • SIDE IMPACT PODS: Positioned on the side of the shell and always engaged, the Side Impact Pods absorb and deflect crash forces during a side-impact crash.
  • ACTIVE SUPPORT HEADREST: Absorption and recovery properties of specialized foams in the Active Support Headrest provide advanced side impact protection that grows with your child.
  • IMPACT DISPERSION ZONE: Strategic placement of EPP foam between the inner and outer shell ensures forces are absorbed into the seat rather than the child.
  • ULTIMATE DAMAGE CONTROL SYSTEM: Koroyd was developed from aerospace safety research & is built into the Knox base & provides advanced impact protection. The tubes crumple instantly on impact, absorbing maximum force, minimizing energy shifted to the child
  • INCLUDED CUP HOLDER: Sippy cup or water bottle, the Knox includes a removable cup holder that can attach to either side of the seat. When spills happen, the cup holder can be used in the dishwasher.

    • Safe and Sturdy
Color: Noa (Navy Melange)
Review Image by Stephanie Nieri Stephanie Nieri
It was time to upgrade our sons car seat as he’s outgrown his other one and we looked at many different options before deciding this was best. First, we trust uppababy brand. We have the infant car seat with the stroller and it was secure, safe, and easy to install. We loved our experience with the infant car seat, we figured we’d have a similar experience with the Knox. We love that you have recliner options for comfort and size. Few things to note though. One; your car size. This car seat is a big bigger (which we actually liked as it felt sturdy and safe) but we’ve been told it doesn’t fit in all cars. Two; it doesn’t have a swivel which we also liked as it seemed safer to us personally. If you have concerns on if it will fit in your car, we’ve been told customer service can help with those questions. We just ordered it and figured we’d try it first hand. All in all, great experience thus far and we’ve had it installed for a few weeks now. ... show more

    • Best carseat ever
Color: Jake (Charcoal)
We've been very happy with this Uppababy carseat model. Use it almost daily and have flown with it as well (using the UPPAbaby luggage for it) and it's holding up good as new! Our 15 month old is comfortable and loves his car rides.

    • Be mindful of size
Color: Jake (Charcoal)
This product was very sturdy and fits within the uppababy brand well that we’ve come to love. Unfortunately this was just too large for our conventional family sedan. It was quite large for our Honda accord which made install a hot mess and It blocked the entire rear passenger window due to the high back design so we had to return it so if you have a small vehicle, I’d look elsewhere but I’d you have a larger car or big suv. This will work just fine for you ... show more

    • Large but does fit!
Color: Noa (Navy Melange)
I rarely write reviews but I decided on this car seat because we loved our uppababy Mesa V2 so much. I have a relatively small car (Honda Fit) and many of the reviews on this car seat made me concerned it would not fit, with people saying they had issues in smaller cars. Sure it’s a big car seat, but most for babies and toddlers of this size are. It fit in my car just fine. I won’t comment on other functions of the seat since we have only used it a short time, but installation was easy and it fits just fine. ... show more

    • Quality car seat
Color: Jake (Charcoal)
This car seat is awesome. My son seems super comfortable in it and he will be able to use it for quite some time. It is very heavy and can be difficult to get setup correctly. We had to move it around in our car quite a bit to make sure it was secured correctly. (We have a small car and I’m not sure how this will vary car to car). Otherwise great seat and price. ... show more

    • Huge!
Color: Jake (Charcoal)
This thing is huge but it feels safe and is easy to clean. Love it. Only downside is how tall it is so sometimes my kid smacks her head getting it lol

    • Best On The Market
Color: Jordan (Charcoal Mélange)
As always, Uppababy’s products are top of the line. The car seat is easy to install and use, and feels solid, unlike cheaper brands. I am a research fiend when it comes to big buys for my kids and this one did not disappoint.

    • Not worth it at all
Color: Bryce (White + Grey Marl)
I have the uppababy stroller so I figured this would be amazing just like it when I got it in. Couldn’t have been more wrong. This car seat is AWFUL! It’s so heavy that you can barely even pick it up to put it in the car, once you get it in it’s almost impossible to install and the indicator never ever turned green and it’s so heavy that it literally didn’t even feel safe at all. If we would’ve been in a roll over I would’ve been scared that the seat belt wouldn’t be able to hold since it was so big and heavy and it probably would’ve crushed my daughter. Rear facing for a 2 year old is impossible because there’s no space at all to get the kiddo in there even in my big SUV and with the tether the kid gets a strap to the face. When we turned her forward facing her head would flop over every time she would fall asleep. She HATED this seat. Our cheaper graco and chicco convertible seats are night and day better than this expensive heavy seat. Would never ever buy this! ... show more
