Transformation of the old armchair

My daughter has brought the old armchair in my apartment last month. 

Together we removed the old cloth and cleaned it thoroughly.

 And that was it! My daughter had to leave.

 I did not have the heart to throw it away, although it looked horrible.

 Then came the boyfriend of my sister with the tools and here is what we 

did.

 What do you think, is it worth the effort?
