The period of time when a girl is on her period and she is using pads (aka mattresses) instead of tampons. Mattress season lasts from the time when the first used pad hits the garbage can until the garbage is taken out at the end of her period. As can be imagined, the worst part of mattress season is the smell that all of the piled up mattress in the garbage create.
