    • Great product
      Verified Purchase

      This product is great, I love that it's slim yet is very comfortable for my LO. I know it's pricey but you get what you pay for, you can use it from birth to 110lbs. And also because of it's slimness I can use three of them in one seat row as we plan to have 2 more in the next five years. It's so easy to install and uninstall if you need to switch cars. It is heavy but that's because of it's metal base, safety first.

      Love them! -narrow -comfortable for kids -easy to use -durable for a long time I won't buy any other car seats. Wish I would have bought these from birth. They are heavy, but safety is far more important!

      The seat is good, but weighs more than most. I do feel that it is safe.

    • fabulous seat
      Verified Purchase

      my husband doesn't like that the clips are not attached to each side of the seat for installation (instead there are two clips on a belt that runs from one side to the other) but overall this seat is sturdy, has great safety reviews, and is slim enough to get three of them across a mid-sized SUV seat. i love it.
