  • Great seat, Love it!

    Good thing is: the car seat is very comfortable with Fantastic Latch System and Easy to install. Bad thing is : the car seat is a little bit large that the person sitting in front of the seat has to move up.

  • Great for forward facing

    We're happy with the car seats we bought, but I do not like how much the backward facing adapter juts the car seat forward. I am 5'4" and was uncomfortable with it backwards behind me. Fortunately we were able to fit it in the middle seat so it's not a problem, but if we weren't able to, I would have returned it.

  • Great Product. Fast Shipping.

    Fantastic carseat. We have been wanting to switch to this carseat for all our littles after we bought one for our ever growing 4 year old. We wanted to keep him in a 5 point harness as long as possible and this fit the bill. It's also much less bulky than the britax blvd that we had before.

  • Great Car Seat!

    This car seat is easy to install and allows for us to fit three car seats in the back of my sedan. My son tells me it is really comfortable too.

  • I feel like my kids are super safe in this car sea

    For my daughter who is now 3 we purchased this same car seat when it was part of the Sunshine Kids line. Becuase of the slimness of the seat (16" wide!) and the materials used for it (steel), while it s a VERY heavy carseat, I feel like my kids are extremely safe in it. So when we needed a car seat for my son, I looked to the new brand of the same seat. I am happy with the improvements that they made to the cushion around the seat buckle and there seems to be a bit more padding in the lumbar area. The only complaint I have about the seat is it's weight, but I feel this also adds value to the safety of it, so the safety outweighs (no pun intended) the heaviness in my mind.

Questions & Answers

Get your product questions answered right here.
  • Why did you choose this product?

    • Highly regarded car seat for safety and extended rear facing option. All steel reinforced frame and 10 year lifespan of seat was also a huge factor.

  • What manufacture year are these car seats? Car seats expire 6 years after the manufactured year and I'm concerned tjese are already a year or two old given the price reduction compared to other sites. All carseats say their year on the car seat.

    • Hello 2underTwo, I hope your day is going well. The date on the chair is September 2014. Thank you for shopping with us and have a great week.
