4th level URL / Folder

[eluser]Unknown[/eluser]
Hi i'm trying to make reasonably easy to understand URLs but i got stock not being able to cerete URi of next level. I want to go something like this:

http://www.example.com/admin/chairs/edit/10

where i already have pages for Admin and Chairs but from Chairs page i want to click edit button and go to next folder (for organizational purposes) and load ID =10 for editing

How can i configure controller? In my controller i have admin.php and in it i was trying to load admin->chairs-> edit

But that did not help
I googled around and found this thread http://glennpratama.wordpress.com/2009/1...deigniter/
but that did not help either

Hopefully some one can help me out, tnx!

In admin.php (controller):

function chairs ($option=0, $id)
{
if ($option == 'edit')
{
// Get data, load views, etc..
}
}
