Which surface provides the greatest reduction in pressure on bony prominences?

• A. Specialized pressure-reducing mattress or overlay
• B. Regular spring mattress
• C. Wooden platform
• D. Soft cotton sheet

Answer: (A)

Reducing pressure on bony prominences comes from surfaces that contour to the body and distribute the body's weight to lower peak pressures. A specialized pressure-reducing mattress or overlay does this best because it redistributes load across a larger area and minimizes localized pressure points. Many of these surfaces use features like air-filled cells, foam with controlled stiffness, or alternating-low-pressure cycles to keep tissues from staying pressed in one spot and to reduce shear when you move. Regular spring mattresses can still create high-pressure points because they don’t conform as well to body contours and can allow uneven support. A wooden platform is rigid and offers little contouring, so it doesn’t significantly reduce peak pressure. A soft cotton sheet is just fabric; it provides minimal support and can increase friction and shear with movement, offering little protection to underlying tissues. So, the surface designed to lower the most pressure on bony prominences is the specialized pressure-reducing mattress or overlay.
