I work for a government agency. An agency big enough that it has dedicated staff and space assigned to the tricky problem of workplace furnishings. If you want a desk altered, or wardrobe changed, you contact said dedicated area to make the arrangements.

Recently our area had a refit. The end result was that in the process of reloading staff into the altered area, some furniture became surplus.

The solution one person chose was to slide their empty cabinet into the corridor and stick a sign on it saying 'Empty - please return.'

Maybe they think it's like the tooth fairy? That somehow, magically, a muscular furniture fairy wearing a back support under their wings, will turn up - having been mystically alerted to the presence of unwanted surplus corridor dwelling furnishings - and spirit the unwanted leavings away to their magical fairy furnishings warehouse until it is summoned once more into the office world.
