      Comments about Frontier 90 - Desert Palm:

      My mom watches my son during the day, and luckily I only work 5 minutes away, so if she needs a car with a car seat she drops me off at work and uses mine, but I always wanted her to have one in case of an emergency. Since she has a brand new Mercedes, she didn't want a car seat in the car all the time. So when I saw how easy this one can be installed, I ordered it right away. I read the directions and installed it within 5 minutes, if that. SO EASY!! I never installed a car seat before – my husband always does it, we have the Britax Boulevard and Britax Marathon, and I never even attempted to try. Love Britax for their great safety review, and so happy that they came out with this Click Tight technology. The Desert Palm color matches her interior perfectly and my 2.5 year old loves the seat! She can take it out and install it herself. Great purchase… GET ONE!!

      Comments about Frontier 90 - Zebra:

      My first initial thought was "wow this heavier than I expected" it's not crazy heavy. It's about the same weight as the Graco Nautilus (I had to replace my Nautilus). I just wasn't expecting it. Not sure why. Fabric is nice, you can tell it won't wear easily. Harness straps are thicker so they won't twist easily. Strap covers are a bit short and bulky, but my daughter didn't seem to mind. The HUGS pads (which I am not use to) don't interfere with or make adjusting anything harder. The harness is a bit of a pain to adjust. The release button to adjust the harness is quite a ways down & you have to do some fishing for it. (I don't normally tighten/loosen the straps every time I put/take the kids out, so it shouldn't be too much of an issue. There is a nice recline feature, and it seems to recline more than the Nautilus does. It seems pretty comfortable. Nice cup holders. There doesn't seem to be too many places that crumbs can end up, which is nice. Chest clip and crotch buckle are both easy to close and open. Installation of the seat with the seat belt took about 20 seconds. Yes, 20 seconds. I'm not use to Britax's 'Versa Tether' so it took me a minute or two to get that figured out and tightened. Overall, I am very impressed with this seat. I can adjust the head rest/harness while the seat is still installed in my car, without a problem.

      My only disappointment in this seat is that the head rest/harness seems a bit flimsy. Which with how much money I spent on this seat, I expect it to be more sturdy. Other than that, I love the seat.

      Comments about Frontier 90 - Cactus Flower:

      I bought two of these seats for my twins on a Friday evening and received them the next day. Couldn't ask for any better service. The car seat was very easy to install after reading the directions. Nice quality and my girls loved the flower design. Very easy to adjust the straps. I feel my girls are safe, love Britax.

        Comments about Frontier 90 - Cactus Flower:

        THIS IS THE BEST BOOSTER SEAT I HAVE EVER SEEN!! IT ALSO SEEMS TO BE THE SAFEST. THEY HAVE THOUGHT OF EVERY LITTLE SAFETY DETAIL. THE SEAT COMES UP AND YOU CAN EASILY PLACE THE STRAP ALONG THE CORRECT PATH THEN BUCKLE THE SEAT BELT OR LATCH STRAP, TIGHTEN IT, THEN PUSH THE SEAT CLOSE UNTIL YOU HEAR A CLICK. THEN THE SEAT IS SO TIGHT, THAT IT WON'T BUDGE EVEN A CENTIMETER. THE HIGHT IS VERY EASY TO ADJUST WITH JUST A SQUEEZE OF A HANDLE. MY DAUGHTER LOVES IT. SHE HAS SLEPT A FEW TIMES WHILE TRAVELING AND IS ABLE TO REST HER HEAD ON THE SOFT HEAD REST. I HAD IT COMPLETLY INSTALLED THE FIRST TIME IN LESS THAN 2 MINUTES. THE CUP HOLDERS R DEEP AND HAS A PLACE FOR SNACKS OR CRAYONS TOO. BUY IT! YOU WON'T BE DISSAPOINTED.

        Comments about Frontier 90 - Onyx:

        We have 4 boys and have purchased 7 Britax car seats/boosters over the years and this is my favorite!!I purchased this seat for our 5 year old because he was growing out of his Marathon. I am SO happy we decided to go with another Britax because this is the best one yet! It is SO easy to install and the quality of the seat is amazing! SO soft and comfortable, my son LOVES it!!The cup holders and arm rests are great and the head support is perfect for when my little guy falls asleep in the car(his head doesn't slump forward).

        The only Con I can mention is that the seat is heavy! I am fine with that though because in my opinion that makes it safer and more secure!

        I feel very confident that we have our boys in the safest seats on the market! You can't go wrong with the Britax:)

          Never installed a seat so quickly and easily!

          I have always been a huge fan of latch and was really nervous to think about installing a seat using the seat belt but this system really works and was a tight fit. Love that the harnesses fit around the little arm rests so you don't have to pull them out from behind your child to get them buckled in. Seems to have great padding and my daughter loves having two cup holders! Another GREAT safe seat by Britax!

          My only "dislike" is that it seems like the harness release button is pretty far back from where the opening is but this is by no means a deal breaker for me!!!
