    • It’s so sturdy but so big!!
I love it and my baby loves it. He’s so comfortable in his new seat! I love how safe and secure it is for him. I was not expecting it to be as big as it is but I have a jeep grand Cherokee and it fits well!

    • Safety, peace of mind, worth the investment
Read details before purchasing for an informed decision. This car seat is designed to grow and protect your child, with comfort in mind and ease of use. It’s sturdy, easy to clean, and looks great. I’m a single toddler mom and I was able to install without issues, brand has a video to watch. My child loves this car seat. I previously used clek travel for reference on transition to a heavy car seat; I found this easy and effective for needs around safety and comfort. ... show more

    • 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

    • Best On The Market
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.

    • I was worried about the size, but it was perfect!

After reading the reviews, I was worried that this car seat might be too big for my vehicle, but our first infant car seat was UPPAbaby and I liked the fact the weight limit was up to 45 pounds rear-facing. So, I still wanted to give it a try and figured I’ll just return it if it doesn’t fit. When I pulled the car seat out of the box, my husband, and I both agreed that it looked enormous! BUT, I am happy to report that the car seat fit perfectly into my Honda HR-V! Currently, I have it reclined with the backrest all the way down and with that it is shorter than my normal car headrest. Currently my car headrests impede my rear view more than the car seat does, so I’m really not worried about that. My vehicle has plenty of room to allow the car seat to grow with my son! I took away one star because the car seat itself is quite heavy. I was able to get it into the car just fine, but carrying it to my car was incredibly difficult, so luckily my husband was able to help me with that. Installation was as easy as running the seatbelt through it and tightening. I really love the UPPAbaby tightening and leveling sensors, so you know when the car seat is installed properly. It’s super cute in blue and seems comfortable and stable! ... show more

    • Safe and Sturdy
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

    • Convoluted Install - Unsafe
Color: Jake (Charcoal)
I'm not one to write reviews, but I have to give this car seat 1 star for the installation alone. After watching the official youtube video over and over for an hour I eventually managed to get the rear facing configuration installed securely. Any time we would need to take the care seat out and move it it was always a chore install again. Front facing is not much better but least the rear attaching strap is mostly out of the way. The safety indicators also provide a false sense of security, as you can have the green indicator and leveling bubbles aligned properly but the car seat it self is very clearly not secure (belt not taut and wobbles back and forth). I write this review drenched in sweat as I've struggled in the Florida heat for about 20 mins trying to get this thing safely reinstalled after our car was detailed. This is after I've uninstalled and reinstalled this thing about a dozen times over the past year. Please avoid this car seat if you value your sanity. UPPABaby clearly whiffed this one. Horrible product. ... 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.
