An elongated mattress core (76) for a mattress structure (50) includes a foam core (66) formed to include a plurality of longitudinally spaced apart transverse slits (130) extending downwardly from a top surface (110). Each adjacent pair of slits (130) defines a foam column (92) so that the foam core (66) has a plurality of longitudinally spaced apart and transversely extending foam columns (92). Each foam column (92) has a pair of generally vertical column side walls (100) defining the slits (130). Each column side wall (100) includes a shear coating (94) having a low coefficient of friction so that each column (92) can compress and decompress without drag forces resulting from frictional engagement with adjacent column side walls (100) interfering with the compression and decompression.

La présente invention concerne une âme (76) de matelas allongée destinée à une structure (50) de matelas et comprenant un noyau en mousse (66) dans lequel sont formées plusieurs fentes (130) transversales espacées longitudinalement et s'étendant vers le bas depuis une surface supérieure (110). Chaque paire adjacente de fentes (130) définit une colonne (92) de mousse de sorte que le noyau de mousse (66) comprend plusieurs colonnes (92) de mousse espacées longitudinalement et s'étendant transversalement. Chaque colonne (92) de mousse est munie de deux parois latérales (100) généralement verticales qui définissent les fentes (130). Chaque paroi latérale (100) de colonne comprend un revêtement contre le cisaillement (94) à bas coefficient de friction de sorte que chaque colonne peut se comprimer et se dilater sans que la résistance au frottement provenant du contact avec les parois latérales (100) des colonnes adjacentes n'entrave la compression et la dilatation.
