HUGS Chest Pads with SafeCell Technology are affixed to the seat shell to ensure proper positioning 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

EZ-Buckle System retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding
  • 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
  • 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
  • Click & Safe® Snug Harness Indicator is an audible aid that provides extra assurance when the harness is within range of appropriate snugness
  • Tangle-Free, Five-Point Harness distributes crash forces across the strongest parts of the body and provides a secure fit
  • 70-pound 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 Insert may be necessary for small infants to achieve a snug fit of the harness around your child (sold separately)
  • Quick-Adjust, No-Rethread 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
  • 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
  • Harness Holders keep harness straps pulled to the sides when placing your child in the car seat

Thus far satisfied with seat, i bought as gift and my son said it was a little difficult to put in vehicle. Also, harder to put child in seat. The most important and satisfying reason for this seat was the safety rating that is why we chose this seat.

Very sturdy made car seat
October 17, 2013
I have been using the infant car seat and thought it's time to move on to convertible. It looks very sturdy and looks very safe. I had bit of time reading the manual to figure out how to move the head board up & down.. (I still can't do it but luckily my husband does) I'm not so sure about the new safety strap because it looks very bulky to me. We are using this car seat in my Benz C250 & prius and we have enough space to have two adults in the back seat with the car seat being installed. So it wasn't taking too much space as what I have read from other reviews.

What a seat! I really like the click indicator that lets you know the child is securely strapped in. It is evident that the seat is very safe as many of the safety features are visible like the side impact technology.
Great safety features, easy to install, comfortable, and harness doesn't tangle

Safe and Secure
April 30, 2013
I like that it feels sturdy and heavy- le'ts me know my baby is safe. I like the fabric as it seems heavy duty and that it will hold up well. I wouldn't recommend this for little babies as the buckles and straps are large and it seemed to swallow my baby. But now that he is bigger, 7 months ( and he is tall for his age, 95%tile) he fits better in it and I feel like he is very well protected. The strap that you pull from the bottom that is supposed to make sure babies are tucked in tight seems a little too tight. I pulled the string til it 'clicked' and it seemed too snug, so I pull until I think it is tight enough. I think I feel that way because my baby is still pretty young. Once he is older, like 1 or so, I'm pretty sure I'll pull string till it clicks. I just seems like it was hurting him at this young age when I pull the string too tight.

Love, Love, Love the Britax Advocate 70-G3 Car Seat

We ordered this carseat for our grandson and we are very impressed. The carseat was delivered ahead of schedule and we received it in perfect condition. It is a very sturdy. I would definitely recommend this car seat.
Very Sturdy and I don't worry about my grandson riding in the car seat
It is really big, it is hard to fit two people and the carseat in our backseat. The instruction book is very detailed but I had to call customer service to check about one thing and they were very helpful and I was able to resolve the issue in a matter of seconds.

Great Car Seat
January 2, 2013
This is a fantastic car seat if you own a large vehicle. Its easy to get your child in and out. Be aware there is a recall on the chest pads, which the company is trading out for new ones that cant be easily chewed. The biggest draw back is if you own a small car. I bought it for use in a Lexus IS 250 but the ceiling height of the car put my childs head close to the roof, so I used it in our SUV. If you own a small car this seat eats up alot of real estate.
Very safe Easy to use and install.
very bulky too big for small cars

Easy installation, easy getting baby in and out. Love the click feature to know when the seat belt is adjusted tight enough. A little bulky - but perhaps necessary for safety features.

This is the second Britax Advocate I have purchased and plan to only purchase this model. It straps in very tightly and my little man is safe and secure! It fits in my car and my SUV. The only way I wouldn't suggest this seat is if you are going to have three car seats in the backseat of a car because of it's size. Two however, fit fine.
