It’s a little ironic that I found the seat in the old XC60 really uncomfortable, yet the seat in our XC40 is great. I’m 6’2″ and 19 stone too.
Which exact model do you have Macca? As far as I can tell (and I’ve only been half following this), the problem seems to be mostly with Inscription Pro models. That car is on my shortlist but these seat issues and the poor mpg being reported is putting me off. Reviews that I have seen say that the best model to get is the R-Design, but I tend to go for luxury over sporty looks.
