Britax Roundabout G4 Convertible Car Seat Reviews

Product Description

The Britax Roundabout G4 convertible car seat is a must-have motor vehicle accessory for car owners with babies. Although simple, this seat is comfortable and secure. In the event of an accident, its revolutionary design and array of integrated technologies protect baby from suffering serious head and chest injuries, and worse, death.


The Britax Roundabout G4 car seat works well. Because of its simple design and responsive features, this chair is user friendly. It fits snugly in nearly all types of vehicles and rarely fails when a child is in danger. For instance, if you are involved in an accident or break abruptly, its energy-absorbing tethers slow forward movements, while its base compresses to stabilize the seat further. Compare with Britax Marathon.

Comfortable – Side Impact Protection System

  • The first notable feature of the Britax Roundabout 50 is its innovating side impact protection system that has saved the lives of hundreds of children.
  • Three components stand out in this system: first, the in-molded shell used to make this chair is rigid and shock proof. Upon impact, it absorbs crush forces, directing them away from your child.
  • The top part of the shell has deep skirts that protect your child’s head and chest. Finally, energy-absorbing EPP foam cushions the system for comfort.


  • Energy-Absorbing Versa-Tether – Apart from its effective side impact protection system, this chair has an energy-absorbing versa-tether that effectively slows forward movement. Its staged-release webbing slows the car seat gradually, which protects your child from injurious crash forces.
  • Apart from the webbing, this tether’s two-point system of attachment not only anchors the seat firmly on the car, but also prevents it from rotating forward. In the event of an accident, your child will stay anchored on the seat until emergency help arrives.
  • Integrated Steel Bars – Road accidents can be brutal, especially if they involve small family cars such as sedans and big ones such as Lorries or tracks. To improve the strength of this convertible car seat and increase the probability of saving your baby’s life, Britax USA has integrated strong steel bars in its design.
  • The bars connect the seat firmly on the vehicle. They also lower forward flexing, a leading cause of debilitating head, neck, and spinal cord injuries in car accidents.
  • Base with SafeCell Technology – The base is made of tough in-molded plastic that fits snugly in all kinds of car seats. In the event of an accident, the base stays snug, while the integrated Safe Cell technology helps to keep your child secure and safe.
  • Upon impact, the base compresses, lowers the center of gravity of the chair, and thus, anchors it firmly on the motor vehicle. The shift of the chair’s center of gravity also absorbs inertia. This lowers forward flexing and the risk of your child crushing on the driver or co-driver’s seat.

Easy Installation Features

Since their inception, installing roundabout car seats has been a daunting chore that many people dreaded. With the G4 Roundabout car seat, however, this is no longer a problem. To ease installation, Britax USA has added the following features:

Unlike its predecessors, this Britax Roundabout car seat has contoured anti-slip base grips that are very easy to handle while installing this chair.
