The Lan Sleeping Posture is just because they don't believe in mattresses, sorry to WWX's sex life.
@Betty WWX internally debating “every day means every day” against the joint pain and coming out deeply conflicted
@Betty probably he eventually talismans his way out, to the ire of every other Lan inlaw once they figure out why he’s so well rested (until he shares, of course)
@Satsuma I mean, from what we know of the Demon Subdue Palace, WWX is either used to it, or has figured something out.
(I mean, actually, he may have dealt with a lack of mattress there by simply not sleeping, it does seem uh... congruent with the facts we know about his time there.)
