A pillow has an outer cover having a first side and a second side that define there between a space for receiving pillow filling. First and second partition walls extend between the first side and the second side to divide the space into first, second, and third chambers, respectively. A closable access mechanism provides access to the first, second, and third chambers so that pillow filling can be selectively added to or removed from any of the chambers to adjust the firmness of portions of the pillow.
