I have a 31.5 inch (inner) leg measurement and find many modern train seats to be uncomfortable for journeys over 30 minutes.
The principal problem being that most seats are simply set too low off the floor (and as the padding flattens they get lower still), which in turn means that unless I can stretch my legs in front of me my knees are always cramped so that there is less than a right angle between both halves of my leg - if that makes sense.
The former GNER Mallard refurbs are the worst examples of this, followed by many of the refurbs on the Sprinter families.
I have yet to find a more comfortable standard class seat than the first refurbs of the original HST seats (the first to lose the separate headrest sections which kept coming loose). Sorry can't recall the seat classification.
