A sofa is made up of many different parts, and every variety creates a distinct look and feel. When choosing a sofa for your home, knowing all the various parts of sofa and couch models, the names of each main part, and its variations can help you describe the style you want to a salesperson or designer. It's also important when judging the quality of a sofa's construction.

Along with learning what the different parts of sofa construction do and are called, it's helpful to take a look at its interior construction. The quality of your sofa depends heavily upon the parts and materials used inside: Hardwood frames, seating support, and the type of cushion filling used can all make a great difference in both comfort and durability over time. These interior parts are wrapped in upholstery (usually fabric or leather) that covers the exterior.
