Abstract

It consists in using a plurality of nozzles 1 suitably distributed in the mould for injection of the foaming material forming the mattresses, said nozzles conveying foams of different density and with different rates of flow and physical properties for the purpose of obtaining areas 2, 3, 4, 5 in the mattress which have different resistance to deformation, those which have to withstand greater forces being more resistant, distributed in accordance with the personalized use anticipated for the mattress.
