A pillow is of rectangular form and formed by adhering together a top part and base part, the top part being of a softer material than that of the base part. The base part has front and rear rolls at its longer sides and side rolls at its shorter sides, upper and lower surfaces of the pillow having respective large, central recessed areas between the front and rear rolls, the rolls being interrupted by minor recesses extending from respective sides of the pillow into the central recessed areas of the upper and lower surfaces respectively, the front and rear rolls forming on each surface a central main buttress and together with the side rolls forming four corner buttresses, side buttresses also being formed between pairs of adjacent corner buttresses respectively, the side buttresses tapering in width and height away from their respective associated sides of the pillow into a central recessed area. The whole of the upper surface of the top part is smooth and its lower surface is adhered to the upper surface of the top part only around their respective perimeters. A large, central void space is defined between the top and base parts in an undeformed state of the pillow.
