A foam in bag cushion precursor is disclosed that is particularly useful for manual operation. The cushion precursor comprises a bag (40) formed of two sheets of flexible plastic film material closed on all four side edges; a frangible seal that defines separate interior cells in a portion of the bag; a first foam precursor composition in one of the interior cells (50); and a second foam precursor composition in another of the interior cells (51). One of the cells has a nonfrangible seal wall (41, 42) other than one of the side edges for directing the contents of the cell to mix with the contents of the other cell before the mixed contents enter the remaining portion of said bag.
