Step 1: Get what you need
Buy a tft-lcd screen wall mount like this, the cheapest one, 9�. The ones more expensive are not valid to this purpose!
Buy a leg for beds. 3�
Buy one screw that suits the big hole on the leg (usually used for the wheel). four screws to fix the leg to a surface. and some screws to fix the tft mount to the IKEA's platform. 3� or less.
