New Designs and Redesigns of Sofa Furniture for Upcoming Season

We are an OEM sofa furniture (leather/fabric) manufacturing company in the process of shifting towards the ODM business model. We need new designs or redesigns of our older styles for our upcoming collections. For each set of furniture design, the designer shall provide, but not limited to, the design concept, the draftings (3D preferred), the measurements (for seating comfortability), and the material use (i.e. exterior, legs, etc.). The designer is expected to monitor and facilitate the creation of the prototype to ensure a perfect representation of their design.
