ABSTRACT:
A firm, shape-retaining mattress made of layers of resilient material separated by a layer of nonwoven material such as jute, which are held in relation to one another by a strong, nonwoven fabric material intertwined among the layers and through slits in the layers in a manner to substantially prevent movement relative to one another.
