We are all different! I have driven my Kuga St Line X often between 1 and 2 hours at a stretch and am comfortable throughout. It did take a bit of adjusting and driving to find the best position with so many changes that can be made, but got their and now happy.
Have also sat in the front passenger seat, again no complaints.
If you can get a drive in a demonstrator this might help you.
Truthfully no one but you can judge how they will be for you.
Agree with GordonM above, we are all different and it is a personal thing. I’m over six feet and have no probs getting a comfy position. As Gordon says perhaps see if you can borrow a demonstrator over a couple of days and have a good drive. I drive from Kent to the Yorkshire Dales and also mid Wales twice a year most years and don’t get out feeling shattered, even though I’m over the hill and half way down the other side age wise.
My seats are all leather and recently in the hot weather I dont like them at all, they get a bit wet with sweat under my legs.
Love them in the winter cos I can put the heated seats on.
Love the electric mode for adjustment too.
But yep the seats are very personal to each and every one of us.
