In this example scene (a scene from Chocofur) I used the beech preset material for the chair (the chair is also from Chocofur. Note that I dropped the bundled textured material and replaced it by the ProWood procedural material). I picked the colors to match and upped the brightness and the reflectivity a bit to get the varnished look of the steam-pressed plywood of the chair. The books were generated by the book wizard cover generator.
For the floor (generated with my floorboard add-on) I used the material preset that is included in the shader pack specifically for the add-on, in this case oak. I just changed the colors. I had to changed the profile in bevel settings of the floor to 0.69 to prevent strange shadows. That has nothing to do with the shaders but everything with the geometry of the planks my add-on is generating, so it might be a good idea to make this the default in future versions.
