The Arc Collection features unique pieces of furniture that are an exploration of one of the oldest features in architectural history, the arch. For their Arc Collection, The Line Concept has re-imagined the arch by using it in multiplied, merged and sectioned versions. Through this, they introduce a play on the geometry and illusion using the arch, while keeping designs simple and practical. As with all their designs, The Line Concept heavily features the use of mixed materials such as solid woods, interesting stones and tones of brass.
