Campaign Chests
During our later forays and UNpleasantnesses, which weren't always quite as unpopular as the Crusades, it was necessary for chaps to take their furniture with them to ensure proper meals and shaving facilities. To prevent a chap's things getting bumped furniture was designed to be protected during transit often with brass corners and folding lids and covers.
It still looks rather nice and is considered preferable to a foam computer bag.
