Rated 5 out of 5 by from Amazing car seat! We have used this for several months now, and our daughter falls asleep in it all the time. It fits super well in our SUV and is very easy to clean. Love all the adjustable settings to make it a perfect fit for our daughter. It assures me that she is safe. I am so happy with this seat and glad we chose it after weeks of looking.

Rated 5 out of 5 by from Stylish and safe! This is great carseat! I've been using it since my son was born, and it has grown with him well. He's 18 months now and a big boy, and it still fits him great! I really love the appearance. It's stylish, sleek and not too bulky. It fits into my suv very nicely. It's also lightweight, and easy to carry around. I'm a small woman, and I had a fairly easy time lugging this carseat around, even with my son inside of it. It's relatively easy to install. Although, the clips can be a little difficult to get unattached from the car. Which can become a hassle if you're planning on switching the carseat back and forth between cars frequently. The straps are a breeze to adjust, you just move them up and down to get the right size, you don't have to bother with taking them out to adjust them. The fabric is high quality, and easy to clean with a simple wipe down.

Rated 5 out of 5 by from Fantastic carseat! We’ve always used Evenflo carseats and this is another great addition to the family! My 11-month old fits comfortably and doesn’t get too warm. Buckles are easily adjustable and installation was about as easy as car seat installation goes. Looks great in the car, too. :)

Rated 5 out of 5 by from All in one car seat! I am very impressed and happy with the Symphony Sport All-in-One Car Seat. With all the options I’m glad I chose this one. I started using this when my son turned six months. It wish I got it sooner. It can accommodate infants from 5-110 pounds. It is extremely easy to install and put in the car. The head rest can be adjusted for height. There are inserts that are included for a smaller infant. It can face the rear and front and it really is all in one. There are cup holders and the material is soft. I’m always in the car driving around and happy my son has this comfortable car seat. I would highly recommend the Evenflo Symphony Sport all in one car seat. Evenflo has amazing quality baby products and I am so happy with this car seat.

Rated 5 out of 5 by from My daughter is just about the age to change to a convertible car seat. This car seat is great as it will last her until she is ready for a booster when she’s older. Pro: love how easy it is to adjust the straps on the car seat with her in it! Love the look and how comfortable it looks I can rear face my daughter easily She sits very comfortably in it. Latch hooks are easy to find and install Straps don’t tangle up Con: Still wish the latch belt was easier to adjust to the car. Can be a struggle at times but I haven’t found a car seat that isn’t ! Over all would buy this again and recommend to my family and friends.

Rated 5 out of 5 by from Comfort for my little man. My son is almost a year old and the seat has worked wonders for my wife and I. I'm good old seat he couldn't seem to get comfortable and was always restless. Now when he gets in his seat he falls asleep almost instant make car rides nice and easy. I'd recommend this seat to any parent

Rated 5 out of 5 by from Great Car seat!! This car seat has been great!! My son is a toddler we are using it as the front facing 5 point harness. My son seems very comfortable in the seat and loves the fact he has more leg room!! I love how easy it is to take in and out of the vehicle. I also love with how easy it is adjust straps and head piece as he grows!! The straps adjust by moving them up and down which is amazing compared to other seats where you have to take them apart and move the straps. The seat is also easy to wipe down and clean! The only thing I would change is the cupholders just having a strap. My son has dropped his drink/toy and I would recommend having an actual cup holder that can be removed and cleaned. Other than my minimal recommendation the seat is great!!

Rated 5 out of 5 by from Great Product! I have had several all-in-one car seats before but this is one of the best. It is light weight and not bulky, it installed easily and quickly, yet is very secure! The material is super soft and comfortable for my baby. I love the adjustable shoulder straps that accommodate my growing child, saves me time messing with the adjustments as he grows. I'm thrilled that it is going to last so long and will grow with my child for many years to come!
