The quote about the mattress highlights the remnants of past love, symbolized by the stains resembling dried flower petals. This imagery evokes a sense of nostalgia and decay, suggesting that the love once present has faded over time. The stains serve as a metaphor for memories that linger, reminding us of moments that once were, and the absence of new love signifies a change in emotional landscape.

In the context of "The Handmaid's Tale," this reflection on love connects to broader themes of loss and the oppressive atmosphere surrounding the characters. With no room for new experiences or relationships, the old love represents a haunting reminder of what has been lost in a world where genuine connections are stifled. Atwood's use of such vivid imagery emphasizes the emotional and societal constraints that shape the characters' lives.
