Inflatable Toast MattressSleeping on this giant 6' by 7' Inflatable Toast Mattress is likely to make you dream that you are a pad of butter and that you are floating down a river of freshly brewed coffee. In reality, you should not use the Inflatable Toast Mattress as a flotation device nor should you expose it to excessive heat. This piece of toast is made of plastic, not bread, so if you wake up and smell burning toast, you are probably just having a stroke.
