One of the seats I build from scratch ,nice vehicles need nice seats ...I don't over look comfort either this seat sets better than any house sofa ...
a word about foam ...have you ever sat on a seat and felt like your but was burning ? can't sit still ...that is what cheap poly foam covered with cheap material does to you ...
With quality foam such as Latex based foam and high end material build right you can sit for hours and not move a inch
Aircraft seats area good example private plane seats are small ...I have customers (friends) who could not fly their planes for 20 minutes until I rebuilt them using the proper foam and density now they can Fly anywhere and feel good when they arrive
