Should an ottoman match the sofa?
Neither matching nor contrasting is the universally right answer. The choice depends on what the rest of the room is doing and what role the ottoman plays in the seating arrangement. A matching ottoman in the same fabric and color as the sofa reads as a set and simplifies the seating area into a single unified statement. In a room where other furnishings are varied in color or texture, that cohesion provides a visual anchor and keeps the seating zone from becoming one more source of competing elements.
A contrasting ottoman adds a second color or texture to the arrangement, which can read as intentional variety or as a mismatch depending entirely on whether the ottoman relates to something else in the room. A velvet ottoman in a deep green beside a neutral sofa reads as a deliberate design choice when the green echoes a cushion, a plant, or a piece of art elsewhere in the room. The same ottoman reads as an error if the green appears nowhere else. The contrasting ottoman needs a visual partner somewhere in the room to read as chosen rather than convenient.
The size and intended use of the ottoman also shifts the visual reading. An oversized ottoman used as a coffee table substitute becomes a furniture statement of its own and is evaluated differently from a small footrest ottoman positioned beside one end of the sofa. The larger the ottoman relative to the room, the more the color and fabric choice matters because there is more surface area making the decision visible.
