A chair with a futuristic and minimal exclusive design, it can be use in any environment thanks to the diversity of materials that can be combined in its multiple parts (you can see an example of this in the 5th render).

The .ksp file is the only one that include materials (glossy white/orange and grey cloth with fuzz), the other formats are divided in layers to facilitate the application of materials.

The Rhinoceros file was made in polysurfaces, the others are meshes as you can see on the wireframe preview.

If you need another version of any file or another format, I would convert it as soon as possible
