Description
  • Rear Facing ? 5-40 lbs (2,3-18 kg)
  • Forward Facing ? 20-65 lbs (9,1-29,4 kg)
The BRITAX ADVOCATE® convertible car seat accommodates children rear facing from 5 to 40 lbs (2,3 to18 kg) and forward facing from 20 to 65 lbs (91, up to 29,4 kg). The ADVOCATE is purposefully designed and engineered to minimize the forward movement of your child’s head during a frontal impact to reduce the risk of head injury with the following revolutionary BRITAX head safety technologies:
  • Base with SafeCell Technology® designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat.
  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash.
  • Energy Absorbing Versa-Tether® features a two-point attachment and staged-release tether webbing to slow the forward movement and reduce the crash forces reaching the child.
  • HUGS? Chest Pads with SafeCell Technology® ensure proper positioning of the chest clip while SafeCells compress to manage energy and provide resistance to the forward movement of your child in a crash.
The ADVOCATE is also equipped with energy-managing Side Impact Cushion Technology, reducing incoming side impact crash energy by 45 percent by diverting crash forces away from the child and incorporates BRITAX True Side Impact Protection® for three layers of side impact protection. The five-point harness is tangle-free with an EZ-buckle system to retain the harness buckle in a forward position while harness holders that keep harness straps pulled to the sides to make boarding quick and hassle-free. Additionally, the Click & Safe® Snug Harness Indicator aids in proper harness snugness. Other features include a no-rethread harness and an easy-remove cover that also allows access to belt paths from the front of the seat, while the multiple buckle and recline positions, comfort pads, and infant positioning pillow provide premium comfort and positioning.

360 Degree Protection Features

  • Side Impact Cushion Technology? features energy-absorbing cushions on the exterior of the child seat to reduce side impact crash energy by 45% by diverting crash forces away from your child and providing extra protection for the adjacent passenger.
  • True Side Impact Protection® is deep side walls with energy-absorbing EPP foam along with a head restraint which offers a double layer of EPP foam to distribute crash forces, shield from vehicle intrusion, and contain the head, neck and body while keeping them ?in true? or aligned.
  • Base with SafeCell Technology® features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
  • Energy Absorbing Versa-Tether® features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
  • HUGS? Chest Pads with SafeCell Technology® ensure proper positioning of the chest clip while SafeCells compress to manage energy and provide resistance to the forward movement of your child in a crash, reducing the risk of head injury.
  • Tangle-Free, Five-Point Harness distributes crash forces across the strongest parts of the body and provides a secure fit
Superior Fit and Comfort Features
  • 65-lb (29,4-kg) Weight Capacity for safety and comfort as your child grows
  • Rear and Forward Facing Recline for child comfort and positioning
  • High Density Comfort Foam provides an extra layer of padding to gently cushion your child
  • Plush, Easy-Remove Cover with matching comfort pads and Infant body pillow to provide extra comfort and easy cleaning without disassembling or uninstalling the child seat
  • Two Buckle Positions for your growing child
  • Infant Positioning Pillow for small infants to achieve a snug fit of the harness around your child
Superior Ease-of-Use Features
  • Click & Safe® Snug Harness Indicator is an audible aid that provides extra assurance when the harness is within range of appropriate snugness
  • Quick-Adjust Harness repositions the harness shoulder height without disassembling the harness straps
  • Premium Lower LATCH Connectors for a quick and simple installation featuring a push button for easy release
  • EZ-Buckle System retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding
  • Harness Holders keep harness straps pulled to the sides when placing your child in the car seat
  • Built-in Lock-Offs ensure a snug lap and shoulder belt installation with minimal effort
  • Anti-Slip, Contoured Base grips and protects the vehicle seat while offering optimum vehicle fit

Favorite car seat
October 27, 2018
We were so picky when buying a car seat! This was soooo comfortable and lasted for a long time. My daughter loveed the comfort of this car seat. With our sedan, the seats were low and all the side cushions made it a lil hard to see her when sitting next to her but with all the security built in on the sides, I didn't mind so much!

Doesn't fit my 4 year old
January 10, 2018
My four year old is 41 inches tall and 43 pounds. She cannot fit in her car seat with her winter coat on. This was supposed to fit her until she was 65 lb and 49 inches. There's no way it is set up properly. We are not the only people who put their kids in winter coats. We bought this seat thinking it was the last one we'd have to buy. It's a lot of money for a car seat that only worked for a couple of years

Looks Good - Instructions could be better
January 5, 2018
We purchase for grandchildren in our auto. New to a first install, it took more time for us. The secret to moving the shoulder straps was to press down on the spring loaded clamp at front of seat base, which has an access pocket over this clamp.

best seat ever/ great company
August 3, 2016
My little girl is my pride and joy so her safety is important to me. This seat does it all and is very simple to use! & britax believes in taking care of your child just as much as a parent would want. I had an issue that they fixed without a blink of an eye, and Quickly!!! I truly appreciate their product and service as a 1st time mom. (all my children will be in their product here on!)

Incredibly Resilient!
June 13, 2016
We bought this carseat when switching my daughter from an infant seat. We LOVE how easy it is to install, buckle, and adjust. It is incredibly resilient to spills, crumbs and other toddler messes, the material cleans up very well! We love this seat! We just bought a marathon for our newborn son!

Love the Advocate!
June 9, 2016
This product has been with us through thick and thin. I bought the Advocate for my son when he was one year old. He is now six years old and still fits comfortably in the seat! I am confident that my son is safe in this seat. The head restraints and steel frame are fantastic features. My son is able to buckle and unbuckle himself. I am able to uninstall and install the seat when needed. The material and seat have held up well through all of the naps and snacks. The option to add a cup holder is nice. I would recommend this product.

Better then putting your kid in a bubble!
June 9, 2016
This seat is fantastic. Easy to take apart and clean and even easier to install in your car. I don't get all hot and angry when I put it in. :) It is a very wide and large seat, but that's where the safety bonuses add up. It's worth the size. I have a very LARGE child who is now 3 and he still fits great in the seat.

Confident in safety
June 4, 2016
I love this car seat because I am so confident that it will protect my child in the event of an accident. But it's also really comfortable for him, he can sleep soundly in it for a couple hours at a time, it is nicely padded and reclined. It is a bit tough to install and take out of the car, and it's big and awkward, definitely not the kind of seat you want to have to switch from car to car daily, but once you get the hang of it it is easy enough to do that once in a while. Though large, it fits fine in the back seat of my Toyota Corolla. I love the seat and so does my child!

Great safety features!
June 4, 2016
We bought this seat for our son when he was 6 months old. He was in it rear facing and is now front facing. The quality of the seat is still great after almost 3 years. The side protection makes us feel that he is very safe! It is also easy to install.

Well made ..

Bought this car seat for my son and with him being on the smaller side it's great that it grows with him and he will be able to use this for a very long time. I love all the impact protection it has as well as all the other many safety features.

Awesome Car Seat!
June 3, 2016
I bought this several months back for my daughter and it is super easy to adjust the shoulder straps for her height all you have to do is push a handle and done! Installation is a breeze using the latch system. My daughter never crys when she is in this seat and we have gone on several long trips with it, from Georgia to Louisiana and from Georgia to Florida. We need to buy another one for Daddy's truck but wanted to make sure our daughter was comfortable before investing on another one. Thanks Britax for an amazing car seat!

June 3, 2016
My daughter transitioned from the Britax infant carrier to this car seat and she absolutely loves it. Not only is it extremely comfortable but it is also safe. After strapping in your little one you pull a strap from beneath the seat until it clicks notifying you that your child is strapped in safely and securely.

Great reliable SAFE car seat!
June 2, 2016
We purchased this car seat over a year ago and haven't had one issue with it. I love the extra side impact features! The straps are easy to use and never tangle. When my little one is in this seat, I have no worries he is truly safe and protected! The material is easy to clean and any food that falls on his lap down the sides can be found easily too. It's very easy to install! It can seem bulky because of the added side impact protection but for what I wanted, I had no problem with that.

Britax convertible car seats are easiest to use!
June 2, 2016
We've used several brands of high end car seats and LOVE our Britax (2 advocates, 2 boulevards) because they are so much easier than other brands to get a tight install. We especially love the locking clips for installation with seat belts. The click tight straps help get a safe harness fit. Great adjustability to kid and great weight range.

Great product
June 2, 2016
We've had this card seat for over a year and it never failed. Provided great protection and safety to the child. Easy to install and secure. Individual hook per side is particularly practical and functional. Easy to take out outer covers to wash and clean. Very happy customer. Price is a bit high, but well worth it. We are getting full usage of it. Our son loves the seat and stays comfortable for long drives, as well.

Better than other brands
June 2, 2016
I bought the Advocate about 2 years ago after my daughter outgrew her infant car seat. I have an infant now and use a Graco infant car seat. I wish I would have purchased a Britax infant car seat. At least in comparison to Greco, Britax mechanisms seem to be much better. I have never had any issues with the Britax and when my older daughter is in it, I feel that she is especially safe. The straps don't get twisted and pull smoothly without much effort.

Very Safe & Comfortable
June 2, 2016
I originally purchased our Advocate (the 70-gs) for my now 4-year-old son when he was 5.5 months old. He used the Advocate rear facing until he was 2.5 and hit 40 inches (the maximum rear facing height limit for the 70-gs) then he turned forward. Shortly thereafter my baby girl needed a convertible seat so now at age 2 she is still happily and comfortably rear facing in the seat and she will eventually pass the seat down to her baby brother. The kids have liked the comfort of the seat, the adjustments have been very easy to make such as the recline, moving straps up, tightening the straps, etc. The cover easily comes off for washing. The only reason I give it 4 vs 5 stars is because the crotch buckle pad fell apart after less than 2 years and because the design of the padding allows vomit into areas that are almost impossible to get clean if you have a kid with a massive amount of vomit (2nd child gets car sick if she has milk within 2 hours of a car ride). The cover holds up great after countless washes, though, and I've learned to get creative with safe ways to clean vomit from nearly impossible to reach places.

I do like this seat one of the top but few issues
June 2, 2016
I love this seat it is easy to install and I feel my daughter (who now is 4 yrs old) is safe. It is heavy and bulky (ill take that if it means she is safe though). And the strap is loose when it clicks so i tighten it more but that to me is a false sense of security. MY BIGGEST PET PEEVE ABOUT ALL SEATS IS CLEANING!!! so much to take off and put back and seems hard to put back together (like a puzzle piece),. Especially with little kids why cant there be an easier way!!! Any additions to the actually seat (like a seat pad etc. is not reccomended because of safety.) NO seat gives safety and easy of cleanliness right now that I have seen.

Cover doesn't fit well
September 14, 2015
I have a two-year-old model of this product. The cover on it doesn't fit well and keeps sliding off about once a week. All the other features that britax describes about the products are correct. Easy to place in your vehicle, easy to operate, great protection, and a quality construction. I have had two of their car seats syles. the boulevard and the advocate. both have been a fine addition to our safety conscious family. The only cons so far are that their car seats are larger than most car seats and require a larger SUV or car to have enough room for you and your child. I am 6 foot 225 pounds and I had to almost have the car seat of my Murano all the way forward to accommodate a rear facing seat behind the driver side. After the car seat was switched from the rear facing to front facing positions then it was easier on my driver side car seat position and no longer feel cramped. I have a Nissan Murano so its not exactly a small vehicle. the other con is the cover slipping off of the advocate after the first year and a half of use. Steve, RN

Everything breaks
August 29, 2015
It seems safe and relatively comfy, but for what you pay for, the nonessential pieces fall apart way too easily. The safecell things on both seats (we have twins) snapped off as soon as the weather got cold. The headrest is just styrofoam and has broken in two places; the only thing holding it together is the cover. The cover of the seat pops off whenever they wiggle, and putting everything back together after washing is a huge pain (not to mention it's not machine washable or dry able, so if you need to wash it, you'd better not need to go anywhere for at least 24 hours while it dries). As I mentioned, we have two of these, and have had the same issues with both.

Very safe
June 10, 2015
It seems to be a super safe car seat, with the airbags and all the lateral support, my baby seems to be very comfortable in it while traveling. The only downside is how difficult is to seat a baby in it, both in and out; for example, it is impossible to seat a baby while sleeping, or take him out and not wake him up. Also, the straps are really short, I hope to find a larger replacement. Overall it is a good seat, and I already recommended it to my friends.

Nice Car Seat
April 8, 2015
I purchased this car seat 2 1/2 years ago for my son. I loved it at the time, but there are so many amazing new car seats out there now that I wish were available then. We have had to replace a few things on this one. Last year we had to replace the foam in the seat as it had deteriorated too much. Now we are having to replace the HUGS Pads that protect the straps, because one thinned and broke... I wish the parts were longer lasting. We bought another carseat in the Marathon series for our daughter the year earlier and have never had a problem.
