 the foam on the top or bottom.  I can't remember exactly.  Remove foam or
 split open area  exposing a captured nut that has most likely fallen
 out(result in slump).  You'll have to figure out how to resecure this nut as
 is likely there is some plastic doodad or spring securing it in place.  Once
 finished, reattach foam by wrapping in duct tape around the whole job.
 recover with material staple back on and voila. its good as new 2 frustrating

not necissarily.  90% of droopy armrests are caused by the allen screws that
hold the shaft to the seat frame coming loose.  thats it.  no need to dissect
the whole armrest.
