Abrégé

A mattress (10) has a mattress substrate (20) and a removable outer comfort covering (30). The mattress substrate comprises a structural core (21) and an allergen-barrier cover (22) that fully encloses the structural core. The outer comfort covering has an outermost textile layer and a filler layer mechanically secured to the outermost textile layer. The outer comfort covering is air and vapour pervious and has in particular an air permeability of at least 200 l/m2/s. The mattress substrate has an outer surface (25) which includes a top face (26), a bottom face (26) and a lateral face (28) that extends from the top face to the bottom face around the entire mattress substrate. The outer comfort covering is applied to the outer surface so that the filler layer faces the outer surface. The outer comfort covering extends over a limited portion of the substrate's outer surface of the mattress substrate so that the entire top face of the outer surface is covered by the outer comfort covering and at least part of the lateral face and/or the bottom face is/are uncovered by the outer comfort covering.
