Slumber is a collection of 3D fabric designed by Aleksandra Gaca. It can be used for aesthetical as well as acoustic purposes. Because of its elasticity and very regular and precise pattern, the fabric is not easy to handle. Therefore Casalis is offering completely finished panels (fabric on frames) that are easy wall mountable. These panels are supplied with acoustic foam for better acoustic performance. Acoustics can also be applied as complete wall covering since panels can be made to measure.
