Answer:
A suite of chairs refers to a collection of chairs that have a similar design or style and are often used together in a specific area or setting, such as a living room or a conference room.
Sets of chairs typically denote a group of chairs that are sold or purchased together as a complete unit, often with a matching design or purpose. For example, a dining set may include a table and several chairs that are meant to be used together for dining.
Groups of chairs can refer to a more general collection or arrangement of chairs, often used to accommodate a certain number of people or to create a specific seating arrangement. It can be a mix of different chair designs or styles put together for a specific purpose or event, such as a meeting or a gathering.
