I bought this "sectional couch" and don't know what furniture style it is or what accessories to use with it.
Thank you,

Did you mean to attach a picture?

A picture would really help. Do you need help figuring out how to attach one?

You should upload the photos, then some one could help you.

If you upload a pic, it will be great. Usually, there is American style, European style, Modern style, Meditteranean style, Neoclassical style, Country style and Oringinal style. You can find some typical pictures of each style to help you.
