Britax Advocate 70-G3 - Onyx

The Britax Advocate 70-G3 convertible car seat achieves revolutionary head safety through the use of Britax SafeCell Technology in the base and HUGS chest pads with SafeCell Technology, integrated steel bars, and energy absorbing Versa-Tether that work together to minimize head excursion and reduce the risk of head injury during a frontal impact. The Advocate 70-G3 also incorporates energy-managing Side Impact Cushion Technology, reducing incoming side impact crash energy by 45 percent by diverting crash forces away from the child. It is equipped with Britax True Side Impact Protection and a Click & Safe Snug Harness Indicator to aid in proper harness snugness. Additional features include a no-rethread and quick-adjust five-point harness, multiple buckle and recline adjustments, and an easy-remove cover that also allows access to belt paths from the front of the seat. A body pillow is provided for extra comfort and infant positioning.

Features:

  • 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 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
  • Base with SafeCell Technology 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
  • Premium Lower LATCH Connectors for a quick and simple installation featuring a push button for easy release
  • Certified for Aircraft Travel

Comments about Advocate 70-G3 - Anna:

Just bought a second one as a replacement due to a car accident, it kept our 20 month old safe! I have used britax with all 3 of my kids and couldn't be happier. Not to mention their customer service was great (my son broke a piece of styrofoam on his boulevard n without hesitation they sent me a new piece). Definitely sticking with britax!

Comments about Advocate 70-G3 - Serene:

Our family was just in a car accident today. We were rear ended while stopped waiting for another car to turn. The vehicle that hit us was traveling at 70 mph. My son was completely safe. I'm buying this car seat again!

    Comments about Advocate 70-G3 - Zebra:

    We purchased this seat to replace our 14 month old son's graco smart seat (hated that thing) and we couldn't be happier with it. Obviously it's huge but since I drive a 2012 town and country and it fits perfectly in the captains chairs, I can't speak for the size in a regular car. I installed it using the latch in just a few minutes. The fabric is so easy to clean, I just wipe it with a wet one. I purchased this in the zebra pattern to match my daughter's frontier 90 and it looks even nicer in person. Overall a great buy. I feel good knowing my little man is secure in this seat!

      Comments about Advocate 70-G3 - Opus Gray:

      We've owned 2 of these for a few years now and I love them! My main desire for getting the side pads was for side crash impact and knowing we'd want 2 kids (and knowing they'd be on either side eventually). Luckily we haven't been in an accident but the peace of mind knowing that I've done everything possible is worth it to me. I have one of the older models and one of the newer ones and I actually like the older one better. It seems like the newer model is a little snug. Like there isn't enough slack in the straps. I do not like the new HUGS technology but know that it can be removed RF. I haven't done that yet but may. Overall, I love Britax and love the Advocate!

      Comments about Advocate 70-G3 - Onyx:

      This carseat is great! It takes a little getting used to if you have an older britax because of the changes, but in this case, change is good! I feel like be daughter is in a bubble when she is riding in the car now! It is a big seat and does take up a lot of room, but I expected that. You really can't go wrong when you buy britax!

        Comments about Advocate 70-G3 - Anna:

        Great quality seat. Very comfortable and many different head rest and recline positions. We drive from NY to FL so comfort for the little ones is important along with safety. We have 1 year old twins and a 5 year old so we recently purchased a Ford Expedition. With the 5 year olds Recaro booster seat and the babies 2 seats all 3 did not fit. But fortunately the middle seat slides forward slightly to fit all 3 in the second row. We also purchased the cup holders (should have been included for the high cost of the seat) but they are nice to have.
        These are large seats, so if you have a compact vehicle you might want to look at measurements first!

          Comments about Advocate 70-G3 - Anna:

          I love this carseat. It has fabulous safety features as well as some great things to make it easy for mom and dad. We have a Britax Marathon for our 5 year old and had one for our 7 year old, and Britax has made significant improvements since then. Not having to rethread the straps when the child grows is amazing as well as the removeable cover that doesn't require unthreading the straps. My daughter is 13 months and petite (18 1/2 pounds), so I wondered if she'd be swallowed by this seat, but it's a perfect fit for her, and she can grow in it, too. And there is actually more room between the middle row of my van and the front seat with this backward facing carseat than with our Graco infant carrier. It was a cinch to install -- took 1 minute.

          I love the pattern, though it's really shades of red and orange, not pink. The background is yellow, not white. It's lovely fall colors -- which isn't really how the picture looks, but I really like it.

          The only downside is how heavy the seat is. It would be a pain to take on an airplane, but the weight doesn't really matter once it's installed in the car.

          It's a great carseat! I am very pleased with our purchase.

          Britax makes wonderful carseats. This is our third (one for the second car and one replacement after a fender-bender). The colors on this particular one are lovely and vibrant, but not overbearing.
