C5 aircross would definitely be a good shout. I’ve sat in one and found the seat very wide. Even whatcar review off it stated that the seats are wide and with not much support, but enough to hold you in place. If you need your seat back a fair bit and sometimes have rear seat passengers then the seats in the back can be moved forward and backwards.
Reviews were slightly mixed but not bad. Basically it’s a car built for comfort rather than thrills.
