I actually have never been to an Ikea store, but I like very much the idea that this might be a helpful walkthrough.
Now make your way into the main SHOWROOM, using the PAPER TAPE MEASURE to throttle anyone who blocks your path.
As you enter the main area, you will see an EKHARD oiled solid-oak dining sideboard. Quickly kick it apart to acquire the TABLE LEG WITH NAIL.
(another good find from Grand Text Auto.)
