A mattress (1), cushion or the like has an outer cover (2) enclosing a resilient core (3). The resilient core (3) is formed by a viscoelastic foam layer (4) with a vapour permeable reinforcing layer (5) of stretchable material laminated onto a top surface (6) of the viscoelastic foam layer (4). The reinforcing layer (5) prevents cracking in the top surface (6) of the viscoelastic foam layer (4) and provides improved heat and moisture dissipation during use. The reinforcing layer (5) is preferably formed by a spaced knitted fabric.

L'invention concerne un matelas (1), un coussin ou autre élément semblable avec un recouvrement extérieur (2) renfermant un noyau élastique (3). Le noyau élastique (3) est formé d'une couche (4) de mousse viscoélastique avec une couche de renforcement perméable (5) faite d'un matériau étirable laminé sur une surface supérieure (6) de la couche (4) de mousse viscoélastique. La couche (5) de renforcement empêche la formation de fissures sur la surface supérieure (6) de la couche (4) de mousse viscoélastique, et permet d'obtenir une meilleure dissipation de la chaleur et de l'humidité en cours d'utilisation. La couche (5) de renforcement est, de préférence, formée d'un tissu tricoté à espacements.
