Britax Advocate Convertible Car Seat

Offering Britax’s highest level of side impact protection, the Advocate Convertible Car Seat combines advanced safety features with a user-friendly design to keep your child safe and comfortable in the car. It’s also packed with user-friendly features like the EZ-Buckle system to keep the buckle out of the way when boarding, a Click & Safe indicator that ensures the harness is properly snug, and multiple recline options. The Advocate accommodates children rear facing from 5 to 40 pounds and forward facing from 20 to 65 pounds.

Choose Only The Best in Safety For Your Child – BRITAX Offers Head Safety Technologies For Advanced Protection

During a car crash, impacts with the front seat aren’t just dangerous – they can be deadly. BRITAX convertible car seats lower your child’s center of gravity to keep them safe, secure and away from front seat. The base of the Advocate includes SafeCell Technology comprised of SafeCells, an engineered material designed to compress in a crash. This compression lowers the center of gravity to counteract forward rotation of the seat, helping to minimize the risk of head injury during a collision. Located in the sides of the seat shell, integrated steel bars strengthen the connection to the vehicle and prevent forward flexing of the seat during a crash to reduce the risk of head injury. 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. In the event of a sudden stop, the Energy-Absorbing Versa-Tether strap restricts forward movement and reduces crash forces with patented staged-release webbing and two-point attachment. This webbing securely anchors the top of your child seat to your vehicle in either rear- or forward-facing positions.

No-Rethread Harness System And Comfort Features

The tangle-free, five-point harness allows for multiple height positions and can be adjusted without dismantling the harness or removing the car seat from the vehicle. Two buckle positions provide a snug, comfortable fit as your child grows. Harness holders prevent the straps from getting in the way when you're putting your child in the seat, while the EZ-Buckle system maintains the harness buckle in a forward position to prevent your child from sitting on it when first entering the seat. High density comfort foam provides extra cushioning, while rear- and forward-facing recline options help your child relax on the journey. And the plush cover comes with matching comfort pads and an infant positioning pillow to keep children of all ages comfortable and secure.

Side Impact Cushion Technology Diverts Crash Forces

Offering both Side Impact Cushion Technology and True Side Impact Protection, the Advocate provides complete protection. Side Impact Cushion Technology, comprised of energy-absorbing cushions on both sides of the exterior of the seat, compress upon impact to divert 45% of the crash energy away from your child while providing protection for the adjacent passenger. Additionally, the Britax True Side Impact Protection system guards your child's head and limits injury by shielding from vehicle intrusion and absorbing crash energy. The car seat has deep sidewalls lined with energy-absorbing EPP foam. This combination diverts crash force energy away from your child while creating a barrier against possible intruding objects. The head restraint offers a double layer of energy-absorbing foam and keeps your child's neck and spine properly aligned in the seat

Click & Safe Technology For The Safest Fit

It's vital that harnesses are properly snug. The Advocate assists in the process of securing your child with the Click & Safe Snug Harness Indicator feature, which provides an audible sound when you're tightening the harness to indicate when it's in the range of appropriate snugness.

User-Friendly Features For Easy Installation

The Advocate takes the guesswork out of installing your car seat thanks to a range of convenience features. An anti-slip, contoured base grips and protects the vehicle seat. Premium lower Latch connectors make for a quick, simple, and tight installation, while the push-button allows you to easily uninstall the car seat. And easy-to-access built-in lock-offs provide a secure installation when using the vehicle lap and shoulder belt.

10-Position, Quick-Adjust Harness

The 10-position, quick-adjust harness repositions harness shoulder height as your child grows without disassembling the harness straps.

Premium Latch Installation

The premium Latch installation provides an audible click and an easy-pull strap to simplify installation as well as a push-button design for easy removal.

Integrated Steel Bars

Integrated steel bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash.

Yes, it costs a lot of money. But it's holding very precious cargo. As a former law enforcement officer, I will only use Britax car seats for my children. They are top rated in safety and perform extremely well on all levels. Through the years, I have used numerous Britax models on my children and have loved all of them. The Advocate G4 Convertible is no exception, I love it. The fabric is soft (and pretty :), the seat appears very comfortable, the straps tighten easily and effectively, it's simple to install and remove from the car, it will last a long time and it has the ultimate in safety features! The absolute only drawback is it's size. It's H U G E. I currently use it in the rear facing mode (and will do so as long as absolutely possible!). However, there is practically no space in the front passenger seat of my Rav4. And forget about putting anyone I the middle seat of my vehicle, because I use two Britax seats, both of which have side impact protection (which makes the seat very wide). BUT, it's the safety features that contribute to the large size of the seat. I'd rather sacrifice space than compromise my children's safety by getting smaller seats. I realize that not all families have this option. But, if you can make it work with less space or if you have a larger vehicle, the Advocate provides a comfortable, stylish and, most importantly, safe ride!

Like many others, I did a ton of research when it came to car seats for my twins. Because they sit on either side of my 4-Runner SUV, instead of in the middle, I wanted more side impact protection. This car seat has it all! While these seats are wider than others because of the extra side impact protection, I found that to be a small price to pay for more peace of mind.

So many well thought out features, including the click you hear when tightening the restraining straps. Also love the Broadway print. Super cute and dark enough that it hides normal wear and stains.

I purchased this for my 12 mo. old since she outgrew her infant car seat. It's very easy to install and use. It seems very comfy and I really like the print. It is very similar to the Britax Boulevard 70 CS that I have for my 3 year old but they don't make that exact car seat anymore. The advocate has the extra side protection. I like that this has the click safe indicator and strapping her in does seem easy to find the straps without having to dig them out from under her.

Fantastic car seat. We put these in the back of the Mazda CX-5. It fits rear-facing, barely. If you are tall you will have a problem. We had to move the driver seat up and put up the recline. I am 5'4" as the driver and I can have the seat comfortable but if you need the seat back more, you will have to put the seat on the passenger side so you can have the passenger seat forward more.

Otherwise, this is a very high quality item. Our child is very comfortable in it. The install is very straight-forward, and the tether, whether rear-facing or forward-facing is very easy to install, at least in the Mazda CX-5. Because of all the protection for the side impact though, the seat is very wide and if you are trying to fit multiple carseats across I would not go with this carseat especially if you have a small car. There is no way you can comfortably get 3 seats across if you need to unless you have a full size SUV like a suburban.

Also, it is big bulky seat, so definitely want to look elsewhere or get a second seat if you are trying to travel on an airplane. You definitely do NOT want to be lugging this seat around.

Overall a fantastic car seat, and per the research, one of the safest you can buy from a very reputable company. Thankfully we have not needed to test that.

I really wanted to like this seat because it isn't extremely heavy and the pattern is super cute! I used it for about 2 weeks, but finally returned it and bought the Clek Foonf instead.

The biggest issue for me was the rear-facing legroom and the difficulty of getting a tight install. My daughter is 13 months old and admittedly tall for her age, but her legs were super scrunched up in this carseat (in my Toyota Highlander). I want her to stay rear-facing as long as possible, and it just seemed like this was already incredibly uncomfortable. I tried the Clek Foonf at BuyBuy Baby and she was able to stretch her legs out almost all the way, so it seems like the Foonf will last much longer as a rear-facing seat. I also liked that the Clek had an entire steel frame and an anti-rebound bar.

I found it difficult to get a super tight install with this seat. No matter what we did, it seemed a little more wobbly than a carseat should. The Clek feels much tighter installed in my car. The installation process for both seemed very similar - threading the seatbelt through the bottom of the seat and using the lockoff clips. (I didn't want to install with LATCH because of the weight limits for carseat+kid using LATCH)

I also found the straps on this carseat really annoying. The carseat seems so bulky and it was really hard to get the straps around my daughter's arms. I understand that the gray plastic protectors are supposed to absorb shock in an accident, but they just seemed really stiff and uncomfortable.

I wish this seat had worked better for us, but it didn't. The Clek Foonf is great so far and I like it much better, although it is incredibly heavy so I would not recommend the Foonf if you need to frequently move the carseat around.
