- Reviewed in the United States on March 29, 2025Color: Sweet BerryVerified PurchaseI love this car seat. I bought this for my 3 year old daughter as her ither car seat needed replacing. It has an easy to clean car seat cover and it comes with a drink cup holder. This car seat is easy to install and take out of the car and it is light weight. The size of the seat is just right for her and it is not bulky. It fits snugly in the car and does not move around once it’s installed.

- Reviewed in the United States on January 4, 2023Color: DuskVerified PurchasePurchased this carseat specifically to be our seat for traveling and we also use it as a back-up seat in if we have a guest who needs a seat. I was super impressed at how lightweight it is! We also purchased (separately) a travel car seat bag that you can wear as a backpack and just slip this seat in and wear it while walking through the airport. It’s easy to transport and sturdy, and then super easy to install into any car or even the smallest of rentals or Ubers and it doesn’t take up much space so you can also still fit 2 adults in the backseat of most standard vehicles plus this car seat.
Wouldn’t necessarily recommend this seat to be your primary seat for everyday use at home or for a long road trip in your own vehicle due to it may not be the most comfortable seat (I.e. the seat back is very straight and it doesn’t recline or anything fancy) BUT for taking along with you while traveling by air and then using it at your destination, you really can’t beat this one! Plus the price is nice so if it gets broken or lost by the airline, it’s not a huge loss. I recommend gate checking it though, less chance of it getting lost.

- Reviewed in the United States on August 4, 2024Color: DuskVerified PurchaseMy 4yr old (42lbs and 43”) outgrew the Scenera and we transitioned to the Finale for our travel purposes as a forward facing harness. It is light weight and easy to install on aircraft or in a rental car. It fits on the Britax car seat cart.
I would say that this car seat lacks any significant padding or “comfort” features but is great for travel and temporary rides (like keeping at a grandparents house). It’s 5 stars bc we use it exclusively for travel and I really value how lightweight and easy it for those conditions. (For comparison, we use a Nuna Rava as our regular car seat at home)
- Reviewed in the United States on October 13, 2019Color: Sport BlueVerified Purchasemy 3 year old fits great, its easy to move around, easy to install, feels safe / decent, and I don't have to ever buy another car seat to replace this one. I got this one for husbands car, he doesn't take our kids as often but one day we forgot to move our sons car seat out of husbands car to my car and he was at work and unreachable and I had to go pick up my kids from school but I had no car seat to be able to put our son in. Another huge bonus is that this carseat is slim, so now it stays in husband’s mini so our kids aren't squished in the back seat like they are with our regular car seat.
**update** my son is now 7 and he still uses this same car seat daily in my husbands car. I really never had to buy another car seat. I guess the best news here is that I am not the only one taking kids to and from school every day anymore 😂
