An air mattress has a plurality of air cells formed in or by an elastic casing. The air cells are connected in series and in parallel with each other by a plurality of air channels. Mattress sections and subsections are formed by combining the channels into groups providing at least one channel group for each section or subsection. Perforations pass through the casing outside the air cells and outside the air channels for ventilating. Air ducts interconnect neighboring mattress sections.
