    • I Recommend this to friends
Color: Olympus Black Style: EveryFit/All4One
We have bought this car seat 3 times. It’s great quality and great price. It doesn’t get too hot in our car and it is aesthetic which doesn’t really matter for a car seat but I think it’s a pro!

    • Not worth the difficulty
Very very difficult to stabilize seat. Some hard plastic at shoulder not covered. Overall not impressed.

    • Love it so cute 👌🏽💯
This is an excellent choice for parents looking for durability, safety, and comfort. It’s a bit of an investment, but the long lifespan and range of features make it worth it. Ideal for families who want a reliable, all-in-one seat without constantly upgrading.

    • Feels too flimsy and unsafe
Color: Olympus Black Style: EveryFit/All4One
I would give this car seat zero stars if I could. Evenflo brand has been around for ages and this seat came highly recommended. I have never returned a purchase so quickly. I opened the box immediately after it was delivered, and found the car seat in the box with no protective plastic, Styrofoam, or cardboard padding to help buffer it from damage. Literally just the seat inside the box with the cup holders and manual tucked behind the infant insert. My first concern was that the car seat had been used and returned, my second concern was that if it had been dropped during transport the safety of the seat could be compromised. Then I began to inspect the seat and noticed that the headrest was extremely wiggly. We have 2 graco seats that have a minor amount of wiggle, but feel very secure. The headrest on this Evenflo car seat had so much wiggle and felt so flimsy that I felt it would break with minimal use or even just by my daughter throwing her head back when mad. There is no way I would trust it to keep my baby safe in an accident. I initiated a return within 3 hours of receiving the car seat, and sent it back. ... show more

    • Pretty!
Even though I read a lot of reviews saying that it was not comfortable that it’s very weird and it was always wiggling but in my opinion, it’s really nice the color is perfect and it’s easy to clean. I love that it has a cupholder and it’s easy to adjust and very comfortable… my baby loves it.

    • Not bad
So I really like this car seat and how puffy the cushions are. The latch system is so easy. The only thing concerning is the plastic back feels a little flimsy. Our other car seats seemed a little more heavy duty. Regardless, it seems to be a good car seat.

    • Purchased for all three of my kids
I have a 4.5-year-old, 3-year-old and 10-month-old. We have this carseat for all three! The quality holds up for the most part. If anything breaks, replacement parts exist! This carseat is super comfortable and I love how it transitions to fit all ages. For the price, I have no complaints. Definitely got my money worth. This carseat is also aircraft certified! My oldest have rode in their carseats right on the plane. The fabric easily comes apart and goes right in the washer machine. Easy to clean and easy to install! ... show more
