Among the three basic shapes of ottoman available, the rounded ones are most preferred for their rounded shapes provides a well intended contrast to the usual sharp angles of the other furniture and hence tends to be the focal point of the room. A round ottoman is not a chair or a table even though you can sit on it or set things on it. It is a piece of furniture that can be many things at once. A round ottoman can serve as a footstool, and it may double as a place for storage as well. Some large models can also be used as a type of coffee table, or even as extra seating. You will want to consider several things when choosing the best round ottoman for your room, such as the size you want, the fabric type and color, the color and style of your other furniture, and the price.
The size of your round ottoman should be partly determined by the size of the room, and it may be best to choose one that is in scale with your other furniture. If you want it for occasional extra seating or as a coffee table, a larger round ottoman will probably be best. If it is primarily for storage and to be used as a footstool, choose one that is more in scale with the seating it will be near. Be sure that it is large enough for the items you want to store, however.
