6. Mismatched Styles

Clashing furniture styles, competing patterns, or an array of uncoordinated decor themes can make your living room feel disjointed and visually chaotic. Designers emphasize the importance of cohesion—choosing a consistent color palette or sticking to a clear design direction helps unify the space. For example, pairing mid-century modern chairs with a contemporary sofa works when the color story or material finishes echo one another. Thoughtful mixing can add depth, but too much variety leads to confusion. For more guidance on creating a harmonious look with mixed styles, check out Elle Decor’s advice on style cohesion.
