So cute, sturdy and soft. Not bulky!
This car seat is very nice, sturdy and the seating is so soft. Not bulky or heavy like other car seats I’ve gotten. Excited to bring my baby boy home in this. Definitely recommend!

Quick and easy!
I’ve bought this car seat base three times now because it makes life so much easier with little ones. We have one in each of our cars so we don’t have to worry about moving just one back and forth. Installation is quick and secure, and I always feel confident that my baby is safe. The seat clicks in and out smoothly, which is a huge help when juggling kids and diaper bags. With two kids (a toddler and a newborn), the convenience of having multiple bases has been a total lifesaver for our busy family. Highly recommend to any parent who wants both safety and simplicity!

Safety first baby carseat
Great beginner carseat for your infant. Has many removable pads that will accommodate for basically any baby size. We just had a 5lbs 5oz boy and he fits in it great. Seems comfortable for him he doesnt move around much and sleeps for a long time in it. The only thing I have a problem with is the way they make you secure the base in the car. One side is only held down which allows it to be able to flip forward and I don't like that but what can u do. I see alot of carseat are made like that and its kind of a terrible design. Other than that it was a great product for the price and I will probably get many years of use out of it
