Pressure sores (pressure injuries) develop when constant pressure and friction reduce blood flow to the skin over bony areas such as hips, heels, tailbone and shoulders. People who spend long hours in bed, who have limited ability to change position, or who have fragile skin are at highest risk. Memory foam mattresses can help redistribute pressure by molding to the body. But not all memory foam is equal, and for people at high risk, a medical-grade surface chosen with a clinician is essential. This guide explains what to look for.
Quick answer: For most people in 2026, the best memory foam mattress for pressure sores is the Consumer memory foam mattress — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
How memory foam helps
Memory foam softens with body heat and weight, allowing bony areas to sink in and spreading pressure over a larger area. This “immersion” and “envelopment” reduce peak pressure points. High-quality foam also recovers its shape between uses, so it does not develop permanent dips that concentrate pressure.

View on AmazonConsumer vs medical-grade memory foam
Consumer memory foam mattresses are designed for comfort. Medical pressure-redistribution mattresses are designed and tested for pressure care, often with multiple foam layers, zoned sections (softer at the heels, firmer in the middle), and covers designed to reduce shear and moisture. In clinical settings, mattresses are often categorized by risk level. For someone who already has a pressure injury or is high risk, follow the care team’s recommendations, which may include alternating pressure or low-air-loss systems rather than foam.
Key features to look for
Foam density and thickness
Higher-density memory foam (often around 4 to 5 pounds per cubic foot for the comfort layer) is more durable and supportive. The overall mattress should be thick enough, often 6 inches or more of foam, to prevent “bottoming out.”
Zoning
Zoned foam offers softer areas under the heels and shoulders and firmer support in the middle.
Cover
A stretchy, vapor-permeable, waterproof cover reduces moisture and shear. Covers should be removable and washable. Tight, non-stretch covers can reduce the foam’s pressure relief.
Temperature
Heat and moisture increase skin risk. Open-cell, gel-infused or ventilated foams help.
Edge support and height
Firm edges help with safe transfers, and correct height makes getting in and out easier.

| Surface | Pressure relief | Typical use | Typical price range |
|---|---|---|---|
| Consumer memory foam mattress | Moderate | Low risk, comfort | $500 to $1,800 |
| Memory foam topper (3 to 4 in) | Moderate | Adding pressure relief to a firm mattress | $80 to $300 |
| Medical pressure-redistribution foam | High | Moderate to high risk | $300 to $1,500 |
| Alternating pressure / low-air-loss | High | High risk or existing injuries | $500 to $3,000+ (often rented) |
Repositioning and care
No mattress replaces repositioning. Clinical guidance often recommends repositioning people who cannot move themselves regularly, commonly every two hours or at intervals set by the care team depending on the surface and risk level. Use pillows to keep knees and ankles apart and to float heels. Check skin daily for redness that does not fade when pressed. Keep skin clean and dry, and manage incontinence promptly. Good nutrition and hydration support skin health.
Matching the surface to risk
Risk assessments used by nurses (such as the Braden Scale) look at sensation, moisture, activity, mobility, nutrition and friction. A person with low risk may be well served by a good-quality memory foam mattress. A person with moderate to high risk may need a medical foam or powered surface. Anyone with an existing pressure injury should have their mattress chosen by their care team.
Heel protection
Heels are one of the most common sites for pressure injuries because the area is small and bony. Even a good mattress may not fully protect them. Care teams often recommend “floating” the heels, placing a pillow lengthwise under the calves so the heels do not touch the mattress, or using specialized heel protectors or boots. Check the heels daily, including the back of the heel, for redness or blistering. Keep the skin moisturized but not wet. Report any changes promptly to the nurse or doctor, since early heel damage can progress quickly.
FAQ
Will a memory foam mattress heal a pressure sore?
A mattress can reduce pressure on the area, but healing requires a full treatment plan directed by a doctor or wound care nurse, including repositioning, wound care and nutrition.
Is a memory foam topper enough?
For low-risk people, a good topper can improve comfort and pressure relief. For moderate or high risk, a medical-grade surface is usually recommended.
Bottom line
For people at risk of pressure sores, choose high-density, zoned memory foam with a stretchy, breathable, waterproof cover, and involve the care team for anyone with high risk or existing injuries. Combine the mattress with regular repositioning, daily skin checks and good moisture control.
