A mattress (10) with an inflatable bladder (12) and an outer border wall (14) to support the outer edges of the bladder (12). The present invention employs foam block border walls that include foam border elements (20, 22, 24, 26) with either an upper (38) or an upper (38) and a lower surface (40) sculpted to present convolutions preferably having generally sinusoidal shapes in vertical cross section. The convolutions allow for a sensation of softness when being deformed, and allow for ventilation of the inner surface, while at the same time, the foam element can be made of a single piece of foam that is of sufficient stiffness to support the outer perimeter surface of the bladder (12) within the mattress (10).

Un matelas (10) comprend un élément gonflable (12) et des parois latérales externes (14) pour supporter les bords externes de l'élément gonflable (12). L'invention fait appel à des parois latérales constituées par des blocs de mousse comprenant des éléments latéraux en mousse (20, 22, 24, 26) avec une surface supérieure (38) ou une surface supérieure (38) et une surface inférieure (40) avec des ondulations ayant, de préférence, une forme sinusoïdale en coupe verticale. Les ondulations donnent une sensation de douceur lorsqu'elles se déforment et elles permettent une aération de la surface interne, pendant que l'élément de mousse peut être réalisé d'une seule pièce qui lui confère une rigidité suffisante pour supporter le périmètre externe de l'élément gonflant (12) dans le matelas (10).
