    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!

    As a Grammy (and a very picky one) my grandchildren’s safety and comfort is my first priority. I was “that Mom” - my car never moved until my boys were buckled into their carseats. How I wish we’d had a carseat this easy to use and as comfortable for them! We’d have eliminated a lot of screaming battles! I purchased this seat for my granddaughter 2 years ago and for my grandson just this weekend. I love the ease of installation - it is truly the easiest on the market. I say that with confidence as I remember the struggle it was to install my boys’ carseats (30 yrs ago) and I was not looking forward to that angst again. My granddaughter never complains about being uncomfortable in this seat and it even has secure cup holders for her sippy cup and snacks which keeps my vehicle cleaner during our outings. Win-win! I highly recommend this carseat to my Grammy/Mimi/Gigi/Nana friends - it’s worth every penny.

    We have been using this car seat for a couple of years now. We absolutely love it. I really like being able to take the buckles and put them in the little slots available so they do not get hot and my son will not get burned by them. It is comforting to know that this model has been side-impact tested and has the impact protection next to my son's head. It has an angle indicator feature on the side that tells you exactly how your car seat should be sitting in your vehicle depending on your child's height and weight. It's so nice to be able to have a carseat that can be both rear and forward facing. I have enjoyed using this carseat for my son and feel like it is definitely one of the best and safest carseats out there. My son has always seemed it's so comfortable while riding in it. He uses his cup holders often. It's nice to have holders that have a strap on the side for cups that are a little bit bigger so it can stretch for the perfect fit. This carseat has provided us with so much peace of mind. It has been a dream and we plan to continue to use it until our son outgrows it.
