The MARATHON 70 also features integrated steel bars, which strengthen the connection to the vehicle seat and reduce the forward flexing of the car seat. In addition, the energy-absorbing Versa-Tether anchors the top of the car seat and minimizes forward rotation of the car seat to reduce the crash forces that can reach your child if an accident occurs. These three features work together as a system to provide revolutionary head safety protection for your child.
Side Impact Protection for Added Security
To keep your child safe in the event of a side-impact collision, the MARATHON 70 includes Side Impact Protection. Side Impact Protection is a system composed of a rigid seat shell with deep side walls and energy-absorbing EPP (Expanded Polypropylene) foam lining the seat shell. These combined features work together to protect your child's head and chest from incoming crash forces by distributing the forces over a larger surface area, helping shield your child from vehicle intrusion and contain your child's head and body in the seat.
Premium Fit and Comfort Features
Whether children are watching the world go by or snuggling in for a nap, they'll enjoy that the MARATHON 70 reclines in both the forward and rear positions. And thanks to additional features, which include high-density comfort foam and a plush cover set with a matching belly pad, they'll always ride in style and comfort. A 70-pound weight capacity, two buckle positions, and a tangle-free five-point harness with ten harness-height settings provide a snug, custom fit for your growing child. Plus, an optional Infant Positioning Insert (sold separately) allows you to properly and snugly fit smaller infants into the car seat.
Ease-of-Use for Safety and Convenience
Packed with perks for parents, the MARATHON 70 makes it easy to secure your child in the proper position without guesswork. Premium lower LATCH connectors make for a quick, simple, and tight installation, while the push-button allows you to easily uninstall the connectors. Easy-to-access built-in lock-offs allow you to install the car seat with ease using your vehicle's lap and shoulder belt. The quick-adjust harness system and buckle allow you to reposition the harness height without disassembling the harness straps.
Additionally, an anti-slip contoured base grips and protects the vehicle seat, ensuring a tight installation in all types of vehicles. Convenient holders keep harness straps out of the way when you're placing your child in the seat, and the plush cover set with matching pads removes easily for cleaning without requiring you to disassemble or uninstall the car seat.
The BRITAX MARATHON 70 Convertible Car Seat is backed by a one-year limited warranty.
