I would not agree with most of the above, and e.g. a C172RG can't be compared with a TB10. Features such as "Lots of glass" makes is a super plane to fly compared to normal "spamcans". Re the seats, I've sat in them for 7hrs a number of times, no issues, but could not spend 7hrs in any chair or any car seat. Short field? TB20 gets off in 350m or so.
