If you look at the Lexus GS 450h as a sport-luxury car, you'll likely be pleased with somewhat narrow, firm buckets that greet the driver and front passenger. Substantial side bolsters are effective at keeping bodies secure, while multiple power buttons provide for a myriad of adjustments. Over the long haul, the chairs prove to be quiet supportive. Comfort accents include a padded center armrest that slides for optimum positioning, padded door armrests and sills, and a power tilt and telescoping steering wheel. On our tester, that last item was wrapped in real wood and leather. It all makes for an inviting ride, though overall room is lacking for taller and wider folks.
