If for example you've got an old squared chair like this, or you see this is the streets, and you don't know what to do with it, here is an example of what you can do.
Step 1: The Cut
Once you got your chair, you just cut the materials. You will get back leather-like surface and foam.
Finally you get a box. I removed the top, which will serve as arrangement for the table to come.
Step 2: The Design
The goal was to have an enlargeable table. So i made drawings and measurements of the table. The idea was to have a working tray, which does not take additional place.
Step 3: The Materials
I wanted to keep an industrial and raw side for this table. Here are the materials I used .
The bracket is there to block the tray but make that we can raise it all the same.
I painted the box with a spray.
Step 4: The Realization
I used a jigsaw, a drill and of which to sand.
Step 5: Final
You can see what it does closed and open; when you remove the tray.
