title: Design pattern - build similar objects
body: <p>I read a book about design patterns, and it give the next question for thinking:</p>
  
  <p>We have some chairs, that build in the same order (first the legs, then the seat and so on..). Their shape is the only thing which different from one to other.</p>
  
  <p>I think about the <a href="http://en.wikipedia.org/wiki/Builder_pattern" rel="nofollow">builder pattern</a>, but when I start to implement it, I discover some problems. There is a better design pattern?</p>
