As people spend more time in home offices, the Workspace section at Design Shanghai has evolved to spotlight some of latest trends and innovation in office furniture.  ESTEL, Italy's leading office furniture maker, for instance, will demonstrate how to designate work and leisure areas at home by using different colours and materials.  Technogym will showcase aerobic and functional fitness products along with a complementary cloud service.  RENSON, a Belgian brand which specialises in natural ventilation systems and sun-protection systems, will introduce sustainable solutions that are balanced with comfort and design. Italian environmental materials pioneer  Tabu and French brand  Tarkett will both launch new products at Design Shanghai.
