Spectrum Highback offers visual and acoustic privacy within an open space. Its tall, upholstered panels create calm islands for focused work or quiet conversation, while preserving the system’s modular fluidity. Soft curves, subtle seams, and slender legs keep the highback light and refined. Whether used alone or in a group, Spectrum Highback carves out comfort, helping users find focus in the collective.
