You're not about to create the Iron Throne from the swords of your defeated enemies so why not play it a little safer by making one with a plastic garden chair and a can of spray paint? Seriously, this garden chair throne is almost as good as the one in Game of Thrones.
Instructables user flaming_pele! put together this DIY guide in shaping an iron throne and it pretty much nails it. The plastic garden chair provides the seat while the swords are made from yardsticks and foam. A nice coat of spray paint finishes it off perfectly.
The process took him three weeks, and sure that's a little bit of time, but it's definitely easier than becoming king of the Seven Kingdoms.
