OKA SpaceLine is a modular acoustic partition system for open-space offices. It fulfils all visual and acoustic space-division requirements with high acoustic effectiveness. Based on a thin aluminium frame, SpaceLine uses seamless upholstery with piping cord completely en­casing the frame. These profiles have innovative oblique grooves, enabling even the piping to be hidden. With no visible profile and seams, the smooth, fabric-covered surfaces determine the appearance of the dividers. Every module has a functional gap running around the edge, situated between the upholstered surfaces and only discernible as a shadow gap. Connectors and accessories can be attached along this gap without the need for tools.
