Under-saddle (1) comprising a flexible base (2) which defines a pair of base surfaces (4, 4′) separated through the relative thickness (6), and a plurality of separation elements (8, 8′, 10, 10′) which extend from at least one (4, 4′) of said surfaces to distance the flexible base (2) from an opposite abutment surface (12, 12′) in contact with said elements. The separation elements 8, 8′, 10, 10′ are reciprocally distributed in such a way that at least a pair of them delimits with the base surface (4; 4′) and with the abutment surface (12, 12′) an aeration chamber or duct (14) open on at least one side. The present invention further relates to a manufacturing method of an under-saddle. |
