Interior decoration is the art of decorating a room so that it is attractive, easy to use, and functions well with the existing architecture. The goal of interior decoration is to provide a certain "feel" for the room; it encompasses applying wallpaper, painting walls and other surfaces, choosing furniture and fittings, such as light fixtures, and providing other decorations for the area such as paintings and sculptures. Interior decorating is done professionally by interior decorators. It is considered a design field. There is a distinct difference between interior decorating and interior design. Interior decorating is generally focused on finishes, such as wallpaper, paint, window coverings, and furnishings. Interior design involves manipulating the architectural integrity of the interior space as well as the creation of a lifestyle experience through the study of human behavior.
Protecting the health, safety, and welfare of the people- is an often-used phrase that identifies some of the knowledge required by all design professions and defines to whom they are all ultimately responsibleâ€"the public. Interior designers make decisions during the design process that will prevent harm from coming to people in environments in which they conduct their daily lives. Harm can be prevented by interior designers use of specialized knowledge when, for example, specifying furnishings and products that are ergonomically sound, subsequently preventing back or eye strain, thereby protecting people's health. Harm also is prevented by planning interior spaces to afford safe exiting and egress that comply with codes, allowing people to escape during a fire emergency, thus providing for their safety. People's welfare is protected by interior designers' knowledge of what creates well-being for people in their spaces; comfort, security, privacy, satisfaction, and stimulation are all components of welfare that are designed into people's environments.
