The couch model with shelves in the left armrest created in Blender 2.90.1. The textures was created in Substance Painter (texture size - 4K). All parts are unwraped. Sofa model saved as one mesh. Available formats: blend file, obj, fbx. Obj and fbx do not contain materials. The proportions of the sofa are fully consistent with real standards. I hope you like it!
