Rear seat is adequate, but it is difficult to install or remove a child seat. The cushion is too firm to make this easy. see full Chevrolet Volt review |

The car is only a four seter so there is no room if you have five people and with the front seats back all the way it is a little tight. see full Chevrolet Volt review |

The rear seats have limited leg room. A forward facing child car seat (Safety 1st Air Protect) is fine but to install it rear facing would make the passenger seat almost unusable and being a 4 seat there is no option to install in the middle of the rear which i find allows in many cars a good way to keep everyone safe & comfortable. see full Chevrolet Volt review |
