  • So cute, sturdy and soft. Not bulky!
Color: Lake Blue 2 Style: Original
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!
Color: Base - Black Style: Extra Base
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! ... show more

  • it fit
Color: Base - Black Style: Extra Base
Perfect fit with the seat. However, I'm not sure how secure it is because of the way it is designed. It wiggles a lot no matter how tight I pull the straps.
