Description



The Britax Marathon 70-G3 Convertible Car Seat ? Onyx accommodates children rear facing from 5 to 40 pounds and forward facing from 20 up to 70 pounds. The Marathon 70-G3 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. The Marathon 70-G3 also incorporates Britax Side Impact Protection to contain the child and protect from the most severe types of crashes. The five-point harness is tangle-free with an EZ-buckle system to retain the harness buckle in a forward position and harness holders that keep harness straps pulled to the sides to make boarding quick and hassle-free. 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 buckles and recline positions, comfort pads, and infant body pillow provide premium comfort and positioning.

Britax Marathon 70-G3 Convertible Car Seat ? Onyx Features:

  • Base with SafeCell Technology
  • Integrated Steel Bars
  • Energy Absorbing Versa-Tether
  • HUGS (Harness Ultra Guard System) Chest Pads
  • Side Impact Protection
  • Five-point harness
  • Multiple buckle and recline positions


Features

  • 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 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 (Harness Ultra Guard System) Chest Pads provides resistance to forward movement in the event of a crash
  • Side Impact Protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body

Comments about Britax Marathon 70-G3 Convertible Car Seat - Onyx:

Because of side protection & 70lb weight capacity which my husbands liked about, we purchased all three car seats from Britax for our kids - one Boulevard for our girl(5yrs)and two Marathon for our boys (3yrs &16month).
Even though these were too bulky & cost a lot, I thought it's ok since these offer safety for my kids (according to description of product). And these seems fine until my kids grow around 40lb & 3yrs old.

Now I am not sure whether we made right decision to purchase these. The buckle is already too short for my boy who is just 3yrs old & less then 37lb. And of course, my girl who is 5yrs & 44lbs, always complains about how uncomfortable she is with SHORT buckle. Frequently I ended up let her not buckle lower one.

I definitely wouldn't recommend to purchase these.

    Comments about Britax Marathon 70-G3 Convertible Car Seat - Onyx:

    I have researched car seats since before my first baby. Britax tests their seats at a faster rate of speed than other seats. Safety is worth paying a few extra dollars. My 6 week old hated her infant seat and so we upgraded to this seat sooner than we would have. We love it, and my baby loves it. Fantastic product.
