  • Choose a sofa if you’re furnishing a formal living room or need a structured piece that contributes to your overall aesthetic.
  • Choose a couch if you’re designing a laid-back space where comfort and lounging are the priority.

Modern retailers often use both terms to describe the same product, so don’t rely solely on the name. Instead, look at the physical design, dimensions, and intended use of the piece before buying.

For multifunctional spaces such as open-plan living areas you can use either a sofa or a couch depending on your priorities. If the room serves as both an entertainment and relaxation zone, consider a hybrid solution like a sectional with tailored lines or performance fabric to balance style and comfort.
