Article comprises an absorbent element (103). The absorbent element (103) comprises a liquid receiving foam layer (104) with open pores in its thickness direction, and a liquid absorbent fibrous layer (105). The liquid receiving foam layer (104) with open pores and the liquid absorbent fiber layer (105) comprise two opposing longitudinal side edges (106, 107; 110, 111) extending in the longitudinal direction, and two opposite transverse side edges (108, 109 ; 112, 113) extending in the transverse direction.
