    Love the seat

    I love this seat! Very clear directions in the manual, and overall easy to install. Unfortunately the seatback in my car slopes down toward the door, so the V tether on the back does not work and slips down one side. No big deal in my car, I just moved the seat into the 3rd row, but keep in mind the shape of your cars seats when looking at car seats. Easy to get the toddler in and out of, even being so far back. Still giving a 5 star review because the seat is awesome, you will not be disappointed if you purchase this.

    The Best!

    I love this seat. We outgrew our boulevard... not officially... but the way my little’s legs were hanging off the front made them hit the back of my seat all of the time. This car seat provides a much better angle for longer legs. Easy to install. I feel safe with my 4 year old in a 5-point harness... and I love that this set up will keep him in it and keep him safe for years to come.



    We are so glad you love this seat! Thanks for sharing your experience with us!
