A substantially planar absorbent core comprising a core wrap enclosing an absorbent material, the absorbent core having a longitudinal axis and comprising a front region, a back region and a middle region, each region having an equal length along the longitudinal axis, wherein the absorbent material is substantially free of cellulose fibers and forms a pattern of absorbent material areas, the core further comprising at least a pair of curved longitudinally-extending channel-forming areas substantially free of absorbent material, through each of which the top side of the core wrap is attached to the bottom side of the core wrap along a core wrap bond, so that when the absorbent material areas adjacent the channel-forming areas absorb a fluid and swells, three-dimensional channels are formed along each core wrap bond, wherein these channel-forming areas are disposed on opposite sides of the longitudinal axis, wherein each of said longitudinally-extending channel-forming areas are longitudinally flanked internally by a first flanking absorbent material area and externally by a second flanking absorbent material area, the first and second flanking absorbent material areas following the curvature of the channel-forming area. n
