    摘要： A mattress comprises an upper surface and a lower surface opposite the upper surface. The mattress further includes first and second opposing side surfaces extending between the upper surface and the lower surface and third and fourth opposing side surfaces extending between the upper surface and the lower surface and between the first and second opposing side surfaces. A core section is formed by the upper and lower surfaces and first and second opposing core section side surfaces and third and fourth opposing core section side surfaces and an extension extends outwardly from a side surface of the core section. The extension is fixedly connected to or integral with the core section and the extension provides the upper surface with a greater area than the lower surface. The extension is capable of supporting a user without a support structure being positioned below the extension.

    摘要： A self-drilling screw is provided which is suitable for use with both relatively thick metal plate and relatively thin metal sheet. The screw is formed from a blank 1 which includes a shank 2 extending between a head 3 and drilling tip 4. The shank 2, adjacent the head 3, is formed with a frusto-conical enlargement 8. A thread 10, when formed in shank 2, is extended into enlargement 8 so as to create a final part 11 of the thread which, in use of the screw with sheet metal 12, distorts the sheet metal such that it firmly locks onto the enlargement 8. A shallow recess 6 is provided in the underside of head 3 surrounding the frusto-conical enlargement 8.
