Sandelio Circle Chair is a good addition for your interior designs. Real size units, with beautiful textures.
In native .blend file you can turn off the particle system for performance reasons. It was added to add a little realism to the object.
Every format archive (.fbx, .obj) includes textures for ease of use. After importing files you need to set up normal and roughness textures as a non color data, otherwise it may give glitchy effects. (maybe not, it did when I was testing it on my end).
Glad if the model helps you!
