Power seats have versatile adjustments. Thigh support is better than some compact SUVs that I compared. Tilt and telescoping steering wheel is flexible for driving position. see full GMC Acadia review |

There are very few SUVs that can seat 7 VERY comfortably that are not HUGE suburban type SUVs. We are very pleased that the 3rd row can truly seat 3 adults with no issues. I love that I can still load it up at Costco by folding the 3rd seat down! see full GMC Acadia review |

Love how comfy it is-- heated seats, (though I would have loved the 2009 A/C seats on my 2008-- boo hoo!), all the controls-- love the music controls on the steering wheel. see full GMC Acadia review |

Have taken this car on long trips, 14 hours of driving, multiple days in a row. The front seats are ok but not very comfortable. It's even tiring for the passenger. see full GMC Acadia review |

With three children having ample rear seat space was very important to us. With the tri zone air system makes it comfortable for them as well. see full Toyota Sienna review |
