What Our Members Are Saying about the Seat Room and Comfort of the 2007 Lexus IS
| 2007 Lexus IS Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2007 | 4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD |
The seats are very comfortable for the size car. see full Lexus IS review |
| 2006 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
The good of the front seat comfort is that the seats are ventilated. They could be stronger and cooler but that is my preference. Why is it that we cant get Audis, BMWs, or Lexus with fabric seats in the US? see full Lexus IS review |

| 2008 | 4dr Sedan 416-horsepower 5.0L V8 8-speed shiftable automatic RWD |
Not enough rear legroom. see full Lexus IS review |
| 2008 | 4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD |
The rear seat really is too small for adults. The front seats have to be moved forward for adults to sit in the back. see full Lexus IS review |
| 2008 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
The rear seats are very comfortable, but TINY. see full Lexus IS review |
| 2008 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
Small rear seat. More like a coupe with 4 doors. see full Lexus IS review |

Even large children will struggle to fit. see full Lexus IS review |
| 2007 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
We do not have small children, and only small children could fit back there. see full Lexus IS review |
| 2006 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
The front seat headrests are too far back for me. I feel if I use them I am looking at the sky because of their angle. I would prefer some fwd-rev adjustment which i have seen on other cars. see full Lexus IS review |

3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review |
