Odysseus and Penelope's Bed

It turns out that Odysseus carved his bed from the roots of a live olive tree. As such, the bed is unmovable. It’s also growing, but evidently that’s not a problem for anyone. The point is that the bed can’t be moved, altered, or shaken – it’s steadfast and constant, much like the love between this royal couple. Odysseus's sleeping around seems not to count, but Penelope’s continuous loyalty is represented by the unmovable bed.
