Comments about Frontier 85 Booster Car Seat - Livia:

THIS WLD BE THE PERFECT CAR SEAT EXCEPT FOR 2 THINGS. FIRST, THE HOLES IN THE BACK OF THE SEAT TO STRING THE SEATBELT THRU R TOO SMALL AND AT A DIFFICULT ANGEL. U WLD HV TO BE BEHIND IT TO BE ABLE TO SLIDE UR HANDS IN TO PULL THE BELT TO THE OTHER SIDE. THEN JUST INSIDE ON TOP OF THE HOLE, THE PLASTIC IS SHARP SO IT CAN SCRATCH UR HAND WHILE U R TRYING TO PUSH THE BELT THRU. THE OTHER ISSUE IS THAT U HV TO TAKE APART THE ENTIRE HARNESS ASSEMBLY TO GET THE COVER OFF TO WASH IT. BESIDE THESE 2 ISSUES, I WLD SAY ITS THE BEST CAR SEAT I'VE EVER SEEN. VERY SOFT, SUPPORTIVE, COMFORTABLE. I THINK IT WLD DESERVE A 5 STAR IN ALL OTHER AREAS. WE RETURNED THIS ONE AND PURCHASED THE BRITAX FRONTIER 90. THE NEWER MODEL HAS CORRECTED BOTH THE ABOVE ISSUES.

    Comments about Frontier 85 Booster Car Seat - Livia:

    I bought this seat for my almost 3 1/2 year old. We both love it. She feels more like a big girl in the seat and it's easy for her to in/out of it. I love that she is safe and secure in it. Was a little difficult to install but not any harder than any other carseat in my opinion.

      Comments about Frontier 85 Booster Car Seat - Livia:

      We have only used Britax car seats and have always been very pleased with them, until now. We bought this booster seat for our 3 year old daughter because she had outgrown her convertable Britax seat. After spending much longer than expected trying to install this booster seat, it was still unstable and moving beyond the recommended limit. Finally, we got the seat installed properly and began using it. After about 20 minutes in the car my daughter started complaining that her back was hurting her. This seat has a flap that pushes into her mid-lower back and it bothers her everytime we are in the car longer than 15 minutes. She has never complained about any of the other Britax seats being uncomfortable, only this one. All in all I am disappointed in this booster seat, and I am going to be buying a different brand.

      Comments about Frontier 85 Booster Car Seat - Livia:

      I have no complaint about the seat itself, I do however, have a major complaint about the installation of this seat. I had four different people attempting to help me install the frontier. It is still a bit unstable. It is incredibly hard to tighten the latch system. God forbid I would have to transfer the seat to another car. I love britax, but this is a major, major, major problem witht his seat.

        Comments about Frontier 85 Booster Car Seat - Livia:

        We have had three Britax carseats, one for each vehicle, and my niece, who is on the petite size really could stay in all of them until she hits 65 pounds. That could be a long time. She so wants to be like the other "Big" kids so we opted to move her up to the booster, pound wise we can. We purchased an inexpensive brand at one of our local retailers, but just never felt that she was as secure in it as she was in the Britax. We actually ended up putting her back in her car seat for the winter snowy months. Once the snow was gone, we started looking again and really like the Harness and Latch system that the Britax comes with, so we purchased one for her to try, figuring we could return it if it didn't feel comfortable. She loved it. Because she loved it so much, we have now purchased a second one which will be shared between two vehicles. Transferring is so easy between the two cars, which we really liked and my Niece loves the look (hot pink) and the feel of her "Big Girl" seat. I would highly recommend this booster to anyone looking for a good seat. Yes, it is a little more money, but our kids are worth it. Spend the extra, you do truly get the peace of mind that comes with the Britax product.

        Comments about Frontier 85 Booster Car Seat - Livia:

        We just got thus seat for my daughter who just turned 4. She is so much happier in it than her previous Decathalon, which I think she had outgrown, despite only weighing 32 pounds. She can easily get in and out of it herself without getting her feet all over the seat of our car. There seems to be plenty of room for growth, which is great since she could be in it for a long time! I don't hear any more complaints about the bottom buckle being too tight. The only complaints I have about it are that it was a little tough to tighten the straps after installing the LATCH clips... much harder to tighten than my other Britax seats. My husband was able to do it for me, but it was not super easy for him either. I also think we may no longer to be able to get 3 seats across our backseat (Honda Pilot), but I haven't tried that quite yet. Overall, I'm really happy we purchased this seat!

          I already have this car seat in my car. And i needed one for her school bus so of course i bought the same one again. I was going to buy a cheaper one but felt guilty putting a price on my child's safety. Its not really light but its not too bulky. And also the hot ponk cplor is fun for a girly girl like mine. Would buy again

          My Husband and I love this seat. We bought two for our 4 year old. We were using Britax Blvd's and our son was starting to get cramped in the back seat with leg room. This seat is still just as protected and safe as the Blvd's but is less bulky. It is also more of a seat which means it's easier on my back and on my son to climb up into it. I have a SUV and this Frontier is perfect. Plus he can use this for so many years it was worth the price. Diapers.com had the best price anywhere online and in store for sure.

          Comments about Frontier Booster 85 Car Seat - Rushmore:

          My 5-year-old son was with me when we figured in a car accident. We were in an SUV and were hit on the right side, most likely just behind the rear passenger seat. The impact made the car flip on its left side and eventually we were upside down. My child was in his Britax Frontier 85, snugly strapped, behind the driver's seat. I crawled to where he was and found him safely strapped in his car seat, never complaining of any pain or soreness, did not lose consciousness, the harnesses never got loose. His only complaint was that he was upside down and it was dark inside the car! An EMS personnel checked the car seat and he said for whatever I paid for that car seat, it was worth my money because it did not even appear like it was just in a car accident. Even my husband, who chides me about buying "these expensive Britax car seats", said it paid off. Our guardian Angels were working overtime that night, as both my son and I escaped the accident without any major complications. But I am also convinced that my son being in his Britax car seat helped keep him safe.
          One thing I would wish the company improve though is the difficulty in installing the car seat. Even after hooking it up to the SUV's safety brackets, the car seat was still somewhat loose when I tried to push it side to side, unlike the Marathon which stays put. Fortunately, this was not a big factor during what happened to us. Thank you, God, and thank you, Britax!

            We use this product for our 4 year old. We are very happy with it. It works well and is very secure. Our daughter can now buckle the harness all by herself. It's been great and we feel she is safe in this car seat. We love Britax products. I really don't have anything negative to say from our experience with this product.

            I have two car seats. teh other one takes about 2 minutes to insall since it has a ratcheting system which allow you to click both sides into the latch clips and then just push the seat in place. The handles for the two latch sides are long and angled on the otehr seat on this seat they are short and difficult to get in place. One in place a silly strap system needs to be tightened. I would not recommend this seat for anyone who intends to move the seat between cars ever.

            Just purchased this car seat for my 3yr old so that we could pass down her other car seat to her sister. Installation is easy if you are used to using the latch connectors. 5 point harness was important to me, and the ability to convert to a booster. Harness is easy to use, just like her old Marathon. She loves climbing into it and loves putting toys and cups in the cupholders. I really have no complaints at this point. It is exactly what I expected from Britax.

            Comments about Frontier 85 Booster Car Seat - Livia:

            We bought this seat for my 5-yr old daughter. She DID NOT want to give up her Recaro Signo, but the bright pink Livia color helped to win her over. Overall, this seat was easy and quick to install. I was also impressed with the way Britax designed the top tether - the belts seems to twist in a weird way with the v-shaped tether belt path, but it works and seems really secure.

            I have two gripes that keep me from giving this seat 5 stars:
            1) My daughter often falls asleep in the car, and to my dissappointment, her head slumps over almost every time... So of course, she wakes up cranky from having the crick in her neck. Grrr. We never had the head-slumping issue in her old Recaro.
            2) My husband hates the rubber pad things on the chest portion of the harness straps, and I don't like them much either. They make it more difficult to properly get the chest clip in the right spot, and my daughter ocassionally complains about them.

            So becuase of the long-ride comfort and daily convenience issues we're having this seat, I'm not as happy with it as I thought I would be. With the way everyone raves about Britax, I guess I had my expectations set a little high. :) We'll definitely keep this seat, but there is no doubt in my mind that the next harnessed booster I buy (for our younger child) will be a Recaro.

              I debated between this car seat and the Graco Nautilus. I bought the Nautilus for my parents and although I like it, it doesn't hold a candle to the Britax Frontier. This car seat is an all around winner and worth the extra money. EASY to install, don't listen to the other reviews. Not any heavier than a normal carseat. With top of the line safety and features comes a little more bulk. Isn't your child worth it. 2 cup holders. THREE settings for the crotch strap which the Graco Nautilus comes up way short on. Slightly reclines child when used as a harnessed carseat, keeping the head back when they sleep. The Graco also fails MISERABLY at this. My kids head ends up flopped forward if he sleeps in the Graco. Well made and the seat is comfortable and the cover seems to be well made and attached.
