A group of furniture is commonly referred to as a ‘furniture set’ or ‘furniture suite’.
These terms describe a collection of pieces that usually complement each other and are designed to work together harmoniously in a particular space or room. For example, a living room set might include a sofa, chairs, and a coffee table, all designed to fit the same style and function within the room.
The idea behind a furniture set is to create cohesion in design, making the space look more organized and aesthetically pleasing. In some cases, you might also hear specific terms like ‘bedroom suite’ or ‘dining set’, which refer to sets of furniture meant for particular areas of the home.
