Rated 5 out of 5 by from Saved my daughters life! Last year (2016) when this car seat became available in Canada we bought it right away because of the safety features (roll over tested). On July 16, 2016, we had a major accident and rolled 7 times. My daughter was with us in her Safemax carseat. She came out with not one scratch. The car seat saved her live. I am so greatful to evenflo for making this car seat and saving my daughter who at the time was 8 months old. I encourage anyone and everyone to get this car seat. You never know when an accident can happen. Thank you evenflo for everything. I can not give enough stars of rating for this.

Rated 5 out of 5 by from Happy Toddler-Happy Mom! My son loves his "big boy seat". His comfort is a priority so we can have an enjoyable cartrip. The adjustable headrest is our favorite comfort feature because my son is taller for his age. The versitility of the seat not only keeps me from having to buy additional seats and boosters over the next couple years but it also means I don't have multiple car seats taking up storage I don't have in my house. Finally, but most important, is the safety features including the rollover tested gives me peace of mind that he is safe as well as comfortable. I love this seat but better yet so does my son and a happy kid makes a happy mom! Highly recommended!

Rated 4 out of 5 by from Comfortable but bulky My daughter was very comfortable in the seat, with the exception of the oversized side impact cushions. While it gives me great peace of mind that she is protected, she was rather upset that she could not see to the side. These cushions are much bulkier than our previous car seats. I also feel as though the latch system could have been upgraded in the car seat. I prefer the quick release attachments as I take my car seats in and out of my vehicle frequently. Overall I would recommend the seat for its comfort and safety features.

Rated 5 out of 5 by from Wonderful Seat! I cannot say enough good things about this seat. The seat is very well padded and roomy, making it incredibly comfortable for my son and the two cup holders are very handy. The straps and buckle are easy to adjust to ensure proper placement and the seat itself is very easy to install correctly. I feel as if my son is well restrained and very safe with this seat.

Rated 5 out of 5 by from Off road family approved My son loves off roading, we did a lot of research and common sense lead us to this carseat. We use this in our jeep only, which only gets used for off roading. Well unfortunately we had to test this carseat out the hard way after miss caculating lead to rolling our jeep. Not only was my son safe as can be after the jeep stopped rolling. He was laughing away. Thank you evenflo we have used your carseat since birth for him and will continue to do so!!

Rated 5 out of 5 by from Wonderful seat! This is such a nice car seat with so many features! It has the look and feel of some other brands that are much more expensive. My son likes it and seems to be comfortable sitting in the seat. It is easy to install and is so sturdy. I love that it is roll-over rated and will keep my little guy safe. I have 3 little boys (and numerous car seats) and this is by far the nicest 3-in-1 we have owned!

Rated 4 out of 5 by from Great car seat I feel comfortable with my child in this seat, especially with the headrest. I love the 3 options. However, I wish it had a rear-facing feature & that it wasn't so heavy.

Rated 5 out of 5 by from Awesome features! I got this seat a week ago and I already lovery it. It's slim now that my guy is forward facing. I love the fact that it will last for so long, up to a booster.
