Spectrum Highback is a modern high-back sofa system designed to create visual and acoustic privacy in open-plan spaces. Its tall, fully upholstered panels form quiet islands for focused work, informal meetings, or private conversations in offices, lobbies, and coworking areas. Soft curves, precise seams, and slender metal legs keep the high back sofa visually light, while the modular design allows linear, corner, and booth-style configurations. Used as a single privacy sofa or grouped into collaborative zones, Spectrum Highback helps define space, reduce noise, and bring comfortable structure to contemporary interiors.

A Quiet Retreat in Open-Plan Spaces

Designed for those seeking calm within the collective, Spectrum Highback is a modern high-back privacy sofa that invites you into a more focused state of mind. This highback variation builds on the fluid design of the Spectrum modular sofa system, creating islands of visual and acoustic privacy in open-plan offices, coworking spaces, hotel lobbies, and educational interiors—without sacrificing openness or elegance. Whether for quiet conversation, deep work, or a brief reset, Spectrum Highback carves out comfortable, sheltered seating in the midst of activity.

Refined yet flexible, Spectrum Highback sofa is engineered for contemporary work and hospitality environments. The tall, upholstered panels provide subtle enclosure, softening sound and shielding distractions, while the modular high-back design supports linear, corner, and booth-style configurations. It works equally well for solo focus, small meetings, or informal collaboration.

True to its name, Spectrum spans a wide range of needs and moods—from intimate focus zones to generous social layouts. This modular seating system speaks the language of architecture, offering clear lines, functional flexibility, and quiet design gestures that make it feel effortless in any open-plan interior.
