Turn Bunk Bed Steps Into a Work Bench

This is my first Instructable so bare with me. 
I stared this project when I couldn't figure out what to do with these steps for bunk beds that i got for free from the local rental center.
I was looking for pallets to build a chicken coop and come home with these bunk bed steps instead.
When i came home my wife said what are those and what are you doing with them. I didn't know what to tell her so I sat and looked at them for a second  on the top step. (my wife shaking her head at me the whole time)
I figured it would make a great sturdy work bench.
