  • Very comfortable, dislike head rest
    by Chaukae

    on December 31, 2019

    I love this car seat so much, we had to get one for our daughter after trying this out for our son. We got the black and red one with a different infant insert though. This one I feel has a poorly designed infant insert, (it is easily removable, which is what we did) it has a bottom piece and a head piece rather than being one long insert, so the middle part where their back goes has no extra padding like their butt and head do, making their head tilt forward too far no matter how far back you tilt the car seat. We actually turned the head rest upside down so that the longer ends are facing up, and we put it behind her back, evening out her posture as if she was using a normal insert that is one piece...other than that, it is very comfortable and very well padded, we love it and wouldn’t go with anything else.

  • Love this seat

    from Winnipeg on December 19, 2019

    This is the second seat we bought. We had bought this for my older daughter last year and loved it so much we purchased for youngest when transitioning her out of a bucket. Would recommend and buy again.

  • Great buy

    This is my second Evenflo Convertible 3in1 car seat. First one I bought for my daughter and I liked it so much I bought another for my son. I like all reclining options and how it can be used as booster so I don’t have to buy so many seats as they grow. The only down fall is that they are a bulkier car seat so if you have a small car then this might not be the car seat for you,I drive a 2018 Tahoe and they both fit in the back seat great. I like how it has extended head rest coming out from the sides in case there where an accident I know they have great head protection. I give this 5!
