The Drive DeVilbiss Silhouette is our top pick for its dual-layer pressure redistribution, while the Medline Overlay offers exceptional value for budget-conscious buyers.
Bed sores, or pressure ulcers, develop when sustained pressure restricts blood flow to vulnerable areas like the heels, hips, and sacrum. A mattress overlay, a specialized pad placed atop an existing mattress, can help by redistributing pressure, reducing shear, and managing moisture. Based on specifications, certifications (e.g., CertiPUR-US, OEKO-TEX), and aggregated owner reviews, we ranked the top overlays for preventing and managing bed sores.
Our research focused on key features: pressure redistribution technology (alternating pressure or foam design), material breathability, ease of cleaning, and durability. We compared over 20 models, weighting owner-reported comfort and effectiveness in both hospital and home settings. Below are our top picks for 2026.
Drive DeVilbiss Silhouette Alternating Pressure Mattress Overlay
This alternating pressure overlay features 130 air cells that cycle inflation and deflation to mimic capillary pressure. It includes a quiet pump with adjustable pressure settings. Owners report significant reduction in sore development over standard foam overlays.

Frequently asked questions
What is a mattress overlay for bed sores?
A mattress overlay is a pad placed on top of an existing mattress to redistribute pressure, reduce shear, and manage moisture, helping to prevent or manage bed sores. They come in foam, air, gel, and hybrid types.
How does an alternating pressure overlay work?
Alternating pressure overlays have air cells that cycle inflation and deflation, mimicking capillary pressure (around 32 mmHg). This changes contact points regularly, preventing prolonged pressure on any one area.
Can a mattress overlay be used with an adjustable bed?
Most alternating pressure overlays require a flat surface for optimal function. Some foam or gel overlays may work on adjustable beds if they are flexible. Always check the manufacturer's specifications.
How do I clean a mattress overlay?
Most overlays have a washable cover that can be machine washed on a gentle cycle. The foam or air mattress should be spot-cleaned with mild soap and water. Always air dry completely before reuse.
How often should a mattress overlay be replaced?
Foam overlays may need replacement every 6-12 months due to wear. Alternating pressure overlays with pumps can last 2-3 years if maintained, but the air cells may occasionally need patching. Follow manufacturer guidelines.
The verdict
The Drive DeVilbiss Silhouette is our overall winner for its effective alternating pressure and quiet operation. For budget-conscious buyers, the Medline Advanced Alternating Pressure Overlay offers great value. The Skil-Care Gel-Filled Overlay is ideal for side sleepers needing targeted relief.
