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 |

The 3rd row seats have enough leg room and the seats themselves are well built. That said, I have not tried the 3rd row seats of close competitors like the Odyssey see full Toyota Sienna review |

The Sienna is an excellent family vehicle if interior space and overall capability are your priorities. It is comfortable for long family drives and you NEVER run out of space in this car. see full Toyota Sienna review |

I have the CE which does not have adjustable lumbar support or 8-way adjustments. The seat has a fixed height, which is a bit too high for me. Also the seat is a bit too deep. see full Toyota Sienna review |

Seat cushion has an uncomfortable contour at rear of seat and the armrests are uncomfortable. see full Toyota Sienna review |

At $35,000 I think it could be much better. Hurts more than my Tacoma 4X4 after a long drive. see full Toyota Sienna review |
