Here's a model inspired by the Othmar Barth (https://de.zxc.wiki/wiki/Othmar_Barth) Chair, Sella project. (https://www.barth.it/)

Model has proper real world scale and is ready to use for your visualization.

Originally the chair was designed on 1962 for the Cardinal Nikolaus Cusanus Academy in Bressanone, then it was produced for further nameable projects. The model has a unique procedural/texturized material with imperfections and scratches that gives the model his old-fashioned heavy used look.

However you can easily change the amount of scratches by editing the material in shade mode:

The model comes with textures (packed in the .blend file; some are originals and some are taken from the free section of www.poliigon.com) and meshes are organized in collections and settings are easily editable.
