Britax Advocate 70 G3 Review - Serene

Britax Advocate 70 G3 – Serene

First of all, the Britax Advocate 70 G3 is the new and improved version of the Advocate 70 CS. Not much has changed. Here’s a list.

  • EZ-Buckle System – keeps the buckle from flipping back into the seat while loading and unloading your child.
  • HUGS chest pads with SafeCells – designed to further minimize crash forces during impact.
  • Side Impact Cushions – They’re black now instead of grey. I guess it’s more aesthetically pleasing.

The Good Stuff


Britax Advocate 70 G3 Review - Side Impact Cushions

Side Impact Cushions

Anybody that buys the Britax Advocate 70 G3 does it for one simple reason, SAFETY. If you aren’t interested in having the safest convertible car seat out there, then don’t buy it because it’s HUGE!

As if it wasn’t obvious, the Britax Advocate 70 G3 is the only convertible car seat that offers Side Impact Cushions.  They have been proven to reduce crash energy by 45%. And as a bonus, they also give extra protection to adjacent passengers. The only way to really describe them is, big plastic bubbles filled with air. You can actually squish them and make “air noises”.

Britax Safety Features2You also get the True Side Impact Protection, which is basically the deep shell and head rest, all lined with EPP (energy-absorbing foam). The Britax Advocate 70 G3 also offers the Click and Safe feature, which is that audible click you hear when the harness is deemed snug enough.

Now, obviously there are many, many more safety features, but in the interest of keeping you around to read my full review, I’ll move on. Read my Britax Safety Features Explained, for more information.

Comfort & Convenience

The fact that you can use the Britax Advocate 70 G3 rear-facing up to 40 pounds is an advantage. Not many convertible car seats offer that high of a weight capacity for rear-facing. And since the NHTSA recommends keeping your little one rear-facing for as long as possible, it works.

The seat itself is quite comfortable, and the seat cover is super soft. Plus, you can get it off without having to take the whole seat apart now. HUGE plus!

Britax Advocate 70 G3 Review - Quick-Adjust Harness System

Quick-Adjust Harness

Also, the Britax Advocate 70 G3 offers a Quick-Adjust Harness. In other words, you DO NOT have to re-thread the harness.  Now, Britax has been offering no re-thread harnesses for quite some time, but this one is really quick. You just grab the handle at the top, compress and slide. That’s it!

The harness holders are also a huge plus, and the new EZ buckle system just adds to the simplicity of getting your child in and out.

The Britax Advocate 70 G3 is also pretty easy to install. You have the option of both LATCH and seat belt installation. Keep in mind that you can only use the LATCH installation for as long as your vehicle allows you to. In other words, most vehicles have a LATCH system with a maximum weight limit of around 40 to 48 pounds. Once you’ve reached this limit, the car seat must be reinstalled using the seat belts. Luckily, the Britax Advocate 70 G3 offers integrated seat belt lock-offs for both rear-facing and forward-facing installation. So at least you don’t have to worry about using those little annoying locking clips.

The Annoying Stuff

Britax Advocate 70 - Customer ImageAs I may have mentioned above, the Britax Advocate 70 G3 is HUGE! Mostly it’s just really wide. It measures 22 inches wide and 21 inches in diameter. So ya, it takes up a lot of space, but I’m guessing you already knew that.

If you have a compact car, chances are this car seat won’t fit. If you have a small to mid-sized car, chances are it will only fit in the center of the back seat. If you decide to put it behind the driver or passenger seat, you may have to move the front seats forward a bit to get it to fit.

You may have to use a rolled up towel  or pool noodle to get the 45 degree angle recommended for infants rear-facing. Honestly, that’s just par for the course when it comes to convertible car seats. It all depends on the slope of your back seat. The Britax Advocate 70 G3 does offer 3 reclining positions, one of which is meant to be used rear-facing, and although this solves the problem for most, it’s just something to keep in mind.

Britax Advocate 70 G3 Review - Installed with older child

The Britax Advocate 70 G3 offers a maximum weight capacity of 70 pounds, obviously. It also offers a maximum height limit of 49 inches. Chances are, your child will outgrow the seat height before the weight. Once again, that’s just par for the course when it comes to convertible car seats.

There are a few other car seats out there with taller seats that may get you by a little bit longer, but they don’t offer near as many safety features.

There was a voluntary recall on the new HUGS chest pads, but that was a while ago.  Apparently, a few kids decided to chew on them and chunks of foam fell off. Talk about a choking hazard! It only affected the Britax Advocate 70 G3 seats made from June 2012 to August 2012. Anything manufactured after that date has the new pads. If you happen to get a seat with the old pads, just call Britax or register your seat online, and they’ll send you new pads for free.


The Britax Advocate 70 G3 is extremely SAFE, comfortable, and convenient. It will allow you to keep your child rear-facing for as long as possible, and it will allow you to keep your child forward-facing and harnessed for as long as possible. At least long enough that you will feel comfortable transitioning them to a belt-positioning booster seat.

As for customer feedback, so far so good. With 16 out of 18 rating the new G3 model 4 to 5 stars, that’s an 89% customer satisfaction rating. The old Britax Advocate 70 CS had 76 out of 84 rate it 4 to 5 stars. That’s a 90% satisfaction rating. If you consider the fact that the new G3 seat is identical to the old one, aside from the EZ Buckle and the new HUGS chest pads, I’d say that’s a pretty good rating.

Like I said above, if you want THE SAFEST convertible car seat on the market, get the Britax Advocate 70 G3!
