When placing your sofa, consider allowing its front legs to rest comfortably on a slightly larger carpet that extends beyond its length. This will create a cohesive look when paired with armchairs that also sit atop the carpet, framing your furniture beautifully. Experiment with different sizes and lay out a floor covering to find the perfect fit for your living room. Don't settle for a smaller rug that would detract from the overall aesthetic – aim for a larger option that will elevate your space.
