Some people take the zombie apocalypse very seriously (though I personally think it will be robots), which is why every last detail must be prepared carefully, especially flooring.
In a debate between laminate versus carpet, laminate seems to reign supremacy in regards to the zombie apocalypse. While carpet is great for insulating rooms, it won't be of much use to you if you're not alive. With laminate, footsteps clearly echo, revealing where the zombie culprit is lurking. Since there is less friction with laminate, furniture can easily be slid across the room in a matter of seconds. Plus, zombie goop can easily be cleaned off a hard surface as opposed to carpet, which stains and traps dirt.
