A futon, or Japanese-style mattress, is described which can be more easily folded for storage and transport. The mattress includes a thick layer of foam with channels dividing it into separate block portions. Cushioning layers lie on opposite faces of the foam layer and a thin flexible outer material surrounds the combination. Ties or tufts extend through the entire thickness of the mattress between the upper and lower layers of the outer material, the tufts extending through the channels between the foam block portions. The tufts extending through the channels enable the mattress to remain in a folded configuration. The mattress can be folded into a S-shaped configuration and placed in an airtight bag, and a vacuum can be applied to the bag to greatly compress the folded mattress, the bag then being sealed to provide a package that can be easily stored and transported.
