Spacious enough to allow my 84 year old mother to get in and out without injuring herself! see full Kia Optima review

After driving the Optima for five days straight for 10+ hours per day, other than the occasional stop, on a road trip, not one time did I get a sore back or thighs. see full Kia Optima review
 

TrueDelta Reviews the Seat Room and Comfort of the 2017 Mazda Mazda6

2017 Mazda Mazda6 Seat Room and Comfort: Cons
YearComment
The Mazda6 has one clear disadvantage compared to the Honda Accord: a much less roomy (if comfortable) rear seat. There are at least three more inches of knee room in the back seat of the Honda, a dramatic difference. Mazda redesigned the Mazda6's front seats for 2018, aiming to make them wider and more comfortable. I found them reasonably comfortable, but not exceptional. The side bolsters are on the small side for a car with some sporting pretensions. see full Mazda Mazda6 review

Why doesn't this vehicle have heated front seats (they only cost a tenner or so at manufacturing time) and why doesn't it have electric front seats with memory (it is particularly annoying to have to try and reset the seat after the garage has had the car and adjusted it to their liking)! Again electric front seats don;t really cost anything much to build in. see full Mazda Mazda6 review
