Britax Marathon 70-G3 Features
Britax is a USA company whose brand name has become synonomous with the safety. What is more important than the saftey of out loved one? The Britax Marathon 70-G3 convertible car seat onyx is designed with safety as it’s top priority. It uses special technology, called the Safe Cell technology to make sure that your child is protected in the event of a crash. This technology ensures that when there is an accident a portion of the seat will compress allowing for the center of gravity to be lowered which counteracts the forward rotation of the child seat which normally pushes the baby into the front seat. This technology also helps to increase the protection on the baby’s head and body in the event of a crash.
The seat has steel bars integrated and an anchor that is energy absorbing in order to help reduce the forces in the event of a crash, it also comes with HUGS ( harness, ultra guard system) and side impact protection which diverts crash forces and EPP foam.
The Britax Marathon 70-G3 convertible car seat has multiple recline positions from both the rear and forward positions. There is also high-density foam and a plush cover equipped with a belly pad that matches. The five-point harness is tangle free and comes with the option to buy an insert for positioning to ensure comfortable fit for smaller sized babies (sold separately)
This car seat is easy to install. The Latch connectors allow for fast, easy and secure installation and the push button makes uninstalling the car seat really simple.
There is no need to remove the seat in order to wash it. The cover of the car seat is easily removable. When choosing a fabric for your seat it’s advisable to choose one that is of velour or cotton fabric as the silver fabric of the Onyx heats up very quickly and can burn fingers when touching it.
It has a 7 year life span and a one year guarentee.
