This is a dining chair version of the Rockabilly bar stool included in Fast Lane Stuff. I use "matching" lightly- the textures are the right color, but the wrong texture. You can just copy them over from the bar stool if you want the exact same match, but it's difficult to get it right in TSRW while making the object.
Since this is cloned from a base game dining chair, it does not require Fast Lane Stuff, but it's a bit shady of you to download it if you don't have it, since I used a mesh from Fast Lane. :p
