Furniture Design Dune Modular Compressed Sofa by Ziel Home Furnishing Technology Co., Ltd Dune is a modular sofa designed for living spaces. The collection includes single-seater, single-seater with armrest and two-seater modules, each 100 cm deep and 75 cm high. Curved forms and warm gradient tones recall sand dunes. High-resilience memory foam and a lightweight, high-strength frame allow each module to be compressed for packing and to regain its full shape after unpacking. Compression lowers transport volume and cost. The modules can be joined to form different layouts. The gradient knit fabric is durable, wrinkle resistant and stretchy.
