Abstract: A pocket-spring core mattress has a plurality of interconnected encased helical springs (8), each helical spring being arranged in a closed pocket (5) made of fabric, nonwoven or the like. The closed pockets (5) are arranged connected to one another as bands (1, 2, 3, 4) in one direction and are connected by adhesive bonding transversely relative to the direction of the bands. Parallel to the direction of the bands (1, 2, 3, 4), between every two adjacent bands there is a connecting wall (9) made of elastic material. The pockets (5) of the bands (1, 2, 3, 4) are respectively bonded adhesively to one another indirectly via a connecting wall (9).
