I should have been more specific.

Various bits of my anatomy = specifically, my legs and back (and shoulders if I remember correctly) in particular. I think the 'joins' of the chair are in wrong places for me. Basically, I find the QF PE seat painful (and thus only ever flown in one once) and found it really uncomfortable. The AVOD handset was also in a strange place and I found the chair very ergonomically unsuitable to me.

However, I am a slender short female so this problem does not apply to many members of this section, who appear to be males and taller than me.
