The Volvo S80 might be the most comfortable and supportive car on the market. My wife has had a bad back all of her life and many surgeries. This car has seats designed by chiropractors and orthopedic specialists and it beats all of the luxury cars out their for comfort, 3-level heated seats front and rear with power adjustments that make it perfect for any sized person. Combine that with whiplash protective seats, the best safety features available and you have a comfortable car that if in a collision will also protect you. I do a lot of research when buying a car and this is the car for the issues I have identified. Combine the price, build quality, engineering, comfort wow!
