Great seat at a great price

We purchased this car seat for my son when he was able to forward face a year ago. When we bought a new second vehicle we wanted to get a car seat for that vehicle so we wouldn’t have to switch back and forth. Buying this car seat was a no brainer. It’s easy to install, my son is extremely comfortable, has cupholders, and the compartments on the arm rests are my son’s favorite. I also love all the safety ratings. If I was to need to buy another one I would definitely buy the same seat.
  • Easy to installs, comfortable, looks great, safe.

Great but could be excellent

I love the seat for its many safety and convenience features. My 5 year old is enamoured with his new comfy seat. Two main drawbacks:
1.Standard LATCH. If I'm gonna pay extra $ for the deluxe model, GRACO please include the upgraded LATCH that are soooo much easier to use! 2. The seat belt pathway is super narrow and a little hard to stick your arm through when trying to install with the seatbelt. The seatbelt easily gets entangled with the unused LATCH harnesses.
  • 1. 10 year life span
  • 2. Steel frame
  • 3. High end weight and height limits
  • 4. Nicely padded
  • 5. Easily adjusted head restraint and harness
  • 6. Head restraint seems really safe
  • 1. Standard LATCH
  • 2. Narrow seat belt path
