Extremly comfortable. You have to sit in it to understand. The leather seat is more comfortable than the cloth seat. see full Chevrolet HHR review |

The rear seat room is relatively large. On long road trips when i am not driving, my back starts to hurt and i cant find a comfortable position to sit in. see full Chevrolet HHR review |
