BRITAX 360 Degree Protection
The BRITAX MARATHON 70 features technologies that work to minimize injury to your child during a crash from any direction, including both frontal and side impact crashes - the most frequent types of crashes. These technologies work together with other features on the car seat to minimize injury to your child during a crash by:

  • keeping your child in the vehicle,
  • diverting crash forces away from your child,
  • helping to slow down your child's body,
  • minimizing movement of your child, and
  • protecting your child's brain and spinal cord.
SafeCell Technology for Advanced Head Safety
Designed with SafeCell Technology, the MARATHON 70 features SafeCells, which are engineered structures located in the base of the seat designed to compress in the event of a crash. This compression significantly lowers the center of gravity and counteracts the forward rotation of the car seat, delivering unprecedented performance in a crash.

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.

Making the right choice when buying a child seat

The first thing to consider when buying a baby car seat is safety! The seat must be appropriate for your babies size and weight. It must also fit correctly into your car. Most retailers are more than happy to give a demonstration and test the seat in your car before you buy.

Even children up to the age of eleven who are not five feet tall must use a child seat of some sort.

Once you have decided on a particular car seat make sure you follow the manufacturer's instructions to the letter. Always allow enough time as fitting a child seat can be very frustrating. Also when it comes to strapping your child in the straps are tight enough to stop the child wriggling free but not too tight to cause the child injury or discomfort. Always give the straps a tug to make sure the seatbelt has locked.

Child Seat Age and Weight Guide

Baby Seats

Babies weighing up to 13kgs and from birth up to one year should be fitted with a baby seat. Baby seats must face backwards and can be installed in either the front or back seats providing the front is not fitted with an airbag.

Child Car Seats

Child car seats are for children aged 9 months to four years. The child must be able to support their own head and weigh between 9 and 18kgs. They face forward and are normally fitted in the back seat of the car.

Booster Seats and Cushions

These types of seats are for children weighing 15 to 36kgs aged approximately 4 to 11 years old. They are primarily designed to elevate the child in order they can safely use an adult seat belt.

Finally and one of the most important aspects to remember is not to get distracted by your child whilst driving. Many accidents are caused from the parent turning round to deal with a child whilst continuing to drive. In the event the child needs attention pull over to a safe location before dealing with the situation.
