The Charlottenborg Exterior Sofa is designed by Arne Jacobsen and is made in Alu-Rattan and ArtFibre materials.

Alu-Rattan is weatherproof powder coated aluminum, and ArtFibre is artificial fibers made of maintenance-free polyethylene that can withstand the sun's UV radiation. Due to the weatherproof materials, the furniture can withstand being outside throughout the year without maintenance.

The Charlottenborg Exterior sofa is fitted with a seat made of Quick Dry Foam. This foam is specially developed for outdoor use as the foam drains water rapidly and maximizes air circulation which enables a faster drying process. The fabric on the seat cushion can be chosen from a broad variety of high-quality fabrics and styles. The cushions are handcrafted, and made to order, at Sika-Design's own studio, located at the headquarter in Denmark.
