Abstract: The foldable carrier comprises first elongate flexible layers that has a first thickness with longitudinal opposite side edges. A second elongate layer is made of a porous soft material that has a second thickness and is secured to the first elongate flexible layer. The second thickness is substantially greater than the first thickness. A first stretcher side section is secured to a first carrier layer and is pivotally attached to one of the side edges of the first elongate flexible layer. The first stretcher side section is movable between an expanded position and a folded position so that the first carrier layer is movable towards the first elongate flexible layer to face the first elongate flexible layer when the first stretcher side section is in the folded position. The first elongate layer and the first carrier layer form a continuous uninterrupted surface attached to the second elongate flexible layer and the first stretcher side section.
