After Mattress Jousting and Mattress Running comes possibly the oddest and the best game requiring a mattress or two. Like Mattress Running you are going to need as many mattresses and bodies as you can get hold of to make the game last as long as possible - making it the ideal dormitory game.
Simply, stand with your mattress held upright and close behind you. The next person does exactly the same half a meter behind you and so on.... a set of human dominoes is created. The first player falls backwards onto the second and the cascade begins.
