Composing lounge furniture with upholstered upholstery and black base bases
Begin with the larger shapes in the room. Identify where the lounge sits, what surrounds it and which view gives the first impression of the seating group. Then examine how the black bases contribute to that composition. They may create a distinct outline against a lighter background or become less conspicuous against a darker one. The actual result depends on the furniture and its surroundings, so assess the relationship directly. Decide whether the base should be a repeated visual detail or a quieter part of the overall form before coordinating the rest of the group.
Use contrast with a specific purpose
Contrast is most useful when it clarifies something in the interior. A visible difference between upholstery and base can draw attention to the separate elements of a piece. A closer visual relationship may give the furniture a more continuous outline. Neither approach is inherently better for a workplace lounge. Compare the complete furniture against the intended background and decide which reading supports the room. Pay particular attention to views where several bases overlap visually. What appears restrained in an isolated piece may become a stronger pattern when repeated across a seating group beside other dark details.
