The horizontal foundation consists of a thin first layer (2), from the one side, made of thoroughly flexible material, highly resistant to wear, having an essentially prolonged foundation shape and a forming holder, and, from the other side, the much thicker layer (3), which is permanently connected to or joined with the holder layer (2) and which consists of a porous or fluffy soft material intended to form the mattress part. The mattress part (3) is divided by one or several lengthwise cuts (4, 4<1>), into which several prolonged sections (5, 6, 7) are to be considered to a joint holder layer (2), or rather the parts (8, 8<1>) forming lengthwise folding lines, that allow the horizontal foundation to be folded into a package, where two sections (6, 7) of the mattress are folded inside towards the other section (5), when the holder layers (2) of the respective sections are turned to face each other. |
