I have a confession. My apartment is 42 square meters and I own five decorative mirrors. That might sound excessive until you factor in the sofa bed situation. Every time my mother visits, I perform a ritual that involves pulling the click-clack mechanism on my velvet upholstery sofa bed, wrestling with a slatted frame that always tries to pinch my fingers, and stacking two twin XL foam mattresses on top of each other to fake a proper guest bed. The result? A living room that feels like a storage unit. My decorative mirrors became the unexpected heroes of this chaos. By placing a large round mirror opposite the sofa bed, I visually doubled the space. Suddenly the room breathed. The aluminum frame caught afternoon light and threw it into corners previously lost to shadow. The trick is not about buying the biggest mirror, but positioning it to reflect something worth seeing. In my case, that something was the window.
