How about making furniture whose purpose is to store down gear?

Perhaps a foot stool type of thing which is a hollow box with a decorative padding on the top and sides, and a lid or hinged side (locking) to accept the down goodies?

A window bench seat …. which does about the same thing.

Maybe generalize the idea into some kind of a couch thing where the underseat space, and maybe the arm space, is filled with down gear.

This is probably a good place to stop.
