Artículo de espuma que comprende: una espuma base que tiene una superficie texturizada; una cubierta de adorno que cubre al menos una porción de la superficie texturizada, comprendiendo la cubierta de adorno: (i) una capa externa terminada que comprende una porción externa en contacto con el ocupante y una porción interna; (ii) una capa amortiguadora comprimible sujeta con respecto a la porción interna de la capa externa terminada; y (iii) una capa de contacto sujeta con respecto a la capa comprimible y configurada para estar en contacto con la superficie texturizada de la espuma base, teniendo la capa de contacto un módulo secante al 5% de deformación de al menos aproximadamente 7 MPa cuando se mide según la norma ASTM D3574-11 modificada, prueba E, prueba de tracción dada a conocer en la descripción.

    There is described a foam article comprising: a base foam having a textured surface; a trim cover covering at least a portion of the textured surface, the trim cover comprising: (i) a finished outer layer comprising an occupant-contact outer portion and inner portion; (ii) a compressible buffer layer secured with respect to the inner portion of the finished outer layer; and (iii) a contact layer secured with respect to the compressible layer and configured to be in contact with the textured surface of the base foam, the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test. There is also described a foam article comprising: a base foam having a textured surface; a trim cover comprising a finished outer layer; and optionally, a contact layer interposed between the foam element and the trim cover, the contact layer in contact with at least a portion of the textured surface of the base foam and comprising a contact material; the foam article having a read through score of at least 20 when measured pursuant to modified ASTM D3575-11 I2 (Procedure B). The present inventors have discovered that the occurrence of “read through” may be obviated or mitigated if the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test is used.
