Within the numerous reviews examined, the car seat was overall well-received. Praised for being lightweight and travel-friendly, it was also commended for its wide seat and recreational features, such as its removable cup holders.

  • Great seat for growing toddlers!
Color: Sport Blue
I got this seat for my growing toddler son who is 3 years old. Just because this is a cheaper car seat doesn’t mean it’s not a safe car seat. I choose this car seat after looking through my options for a few days/ weeks. I ended up going with this one through the reviews I read. All car seats are safe! They protect our babies. Not having one and reading the instructions and following them is what makes them unsafe! ... show more

  • Great for compact spaces
Color: Dusk
These are nice. We wanted something a lot less bulky but still needed a 5 point harness. They sit a little lower but take up much less space. The cup holder needs to be a little deeper. Drinks fall out sometimes when driving.

  • Easy to use and clean car seat for toddlers
Color: Sweet Berry
I 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. ... show more

  • Great backup seat!
Color: Rainbow
Easy to install, lightweight and a nice color. Straps are easy to tighten! Cup holder is nice to have. It feels secure and safe. It doesn’t feature the most high quality fabric or cushioning, but expected with the low price. It’s a great second seat when traveling or for grandparents to take in and out. I’ve had this a week, as far as durability goes, I’m not sure. So far it’s been great! ... show more

  • Much Better than Expected
Color: Rainbow
I’ve spent top dollar on car seats over the years. I needed to buy one to keep with relatives for out of state visits. I am so pleased with the car seat that I will soon be buying a third for daily use. It is a safer, more stable, and easy to install car seat than the expensive Graco seats I’ve purchased in the past. ... show more

  • Great Travel Car Seat
Color: Dusk
My 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) ... show more
