Why this decision matters: Pressure injuries — bed sores — are one of the most painful, costly, and preventable complications in patient care. Once a serious pressure injury develops, healing can take months, require hospitalization, and in vulnerable patients become life-threatening. The right mattress system is not a comfort upgrade. It is a clinical intervention that can prevent all of that from happening in the first place. This guide tells you who needs one, how they work, and which specific system is right for your patient's situation.
At Medical Department Store we work with patients, family caregivers, discharge planners, and home health agencies across Southwest Florida — Fort Myers, Naples, Sarasota, Venice, and Port Charlotte. Pressure relief mattress questions are among the most common clinical questions we get. The patients who come to us have often already had a bad experience — a standard foam mattress that was not adequate, a system that was too complicated for a home caregiver to manage, or equipment that arrived without anyone explaining how to use it.
We are going to give you the straight answers here.
What Causes Pressure Injuries — and Why Mattresses Matter
A pressure injury develops when sustained pressure on skin and underlying tissue cuts off blood flow. Tissue deprived of circulation begins to break down — initially showing as redness that does not blanch, progressing to open wounds that can extend to bone in severe cases. The areas most at risk are wherever bone is close to the surface: heels, sacrum, tailbone, hips, shoulder blades, and the back of the head.
Pressure alone is not the only culprit. Moisture from perspiration, incontinence, or wound drainage softens skin and dramatically increases its vulnerability to breakdown. Friction and shear — the forces created when a patient slides in bed or is repositioned without being properly lifted — compound the damage. All three factors together create the conditions for rapid, serious tissue injury in vulnerable patients.
A therapeutic mattress system addresses all three. It redistributes pressure so no single point bears prolonged loading. It manages moisture through air flow across the skin surface. And it reduces friction by providing a surface that moves with the patient rather than against them. No standard foam or spring mattress does any of these things adequately for high-risk patients.
Who Is at High Risk
The patients who need therapeutic mattress support most urgently are those with limited or no ability to reposition themselves — but risk is not limited to fully immobile patients. Any combination of the following elevates risk significantly: limited mobility or prolonged bed rest, poor circulation or diabetes, fragile or compromised skin, incontinence or high moisture exposure, recent surgery especially involving the hip or spine, advanced age, significant weight loss or poor nutrition, or a history of previous pressure injuries.
In Southwest Florida's warm, humid climate, skin maceration from perspiration and moisture is a more persistent challenge than in drier climates. Low air loss systems that actively manage the skin microclimate are particularly valuable for our patient population.

How These Mattress Systems Work
Alternating Pressure
Alternating pressure mattresses contain a series of air bladders or cells arranged in alternating zones. A pump inflates and deflates the zones in timed cycles — typically every 5–10 minutes — so that different areas of the body are relieved of pressure at different times. No single point bears sustained pressure for more than a few minutes before the cycle rotates relief to that zone. This continuous cycling is what makes alternating pressure systems effective for patients who cannot reposition themselves — the mattress does the repositioning work for them.
Low Air Loss
Low air loss systems add a second mechanism to alternating pressure: a gentle, continuous flow of air through the mattress surface that creates a microclimate of reduced heat and moisture at the skin-mattress interface. This airflow keeps the skin drier and cooler than any static surface can — directly addressing the moisture component of pressure injury risk. For patients with existing wounds, fragile skin, or incontinence, the moisture management of a true low air loss system is not a comfort feature. It is a clinical necessity.
Combination Systems
The most advanced systems combine alternating pressure, true low air loss, and in some cases lateral rotation — physical turning of the patient — in a single integrated unit. These are appropriate for the highest-risk patients or those with complex overlapping needs. See our companion guide on lateral rotation mattress systems for that category.

Pressure Injury Stages — What They Mean for Mattress Choice
Understanding pressure injury staging helps match the right level of intervention to the patient's current condition. The staging system is standard across clinical settings:
| Stage | Description | Mattress Priority |
|---|---|---|
| Stage I | Intact skin with non-blanchable redness — earliest sign | Prevention — alternating pressure system now, before progression |
| Stage II | Partial thickness skin loss — shallow open wound or blister | Active treatment — combined alternating pressure + low air loss |
| Stage III | Full thickness skin loss — visible fat, no bone/tendon/muscle visible | High-performance system — MA800, Protekt 9900, or lateral rotation |
| Stage IV | Full thickness tissue loss — bone, tendon, or muscle exposed | Highest acuity system — MA900 or PreserveTech lateral rotation |
| Unstageable | Full thickness loss — base obscured by slough or eschar | Treat as Stage III/IV — call us to discuss: 866-218-0902 |
Stage I redness is the time to act — not Stage III. Every stage of progression is harder to heal, more painful for the patient, and more costly to treat than the stage before it. If a patient has any risk factors and is spending significant time in bed, a therapeutic mattress system is a prevention investment, not a treatment expense. Call us before the wound develops: 866-218-0902
Overlays, Pads, and Prevention Mattresses
Not every at-risk patient needs a full powered alternating pressure system. For lower-risk patients or those who need additional support on top of an existing mattress, foam overlays, gel pads, and prevention mattresses provide meaningful pressure redistribution without the complexity or cost of a powered system.

Frequently Asked Questions
What is the difference between alternating pressure and low air loss?
Alternating pressure systems cycle inflation and deflation of air zones to redistribute pressure across the body — different areas are relieved of pressure at different times. Low air loss adds a continuous gentle airflow through the mattress surface that manages heat and moisture at the skin interface. Most clinical systems combine both. For patients where moisture is a primary concern, true low air loss capability is an important distinction to confirm when choosing a system.
Can these mattresses be used on a standard home hospital bed?
Yes — most alternating pressure and low air loss systems are designed to fit standard hospital bed frames including the home hospital beds we carry at MDS. Confirm mattress dimensions against your bed frame before ordering. Call us if you need help confirming compatibility: 866-218-0902.
How often should the pump settings be adjusted?
Most systems are set at setup to the patient's body weight and condition, then reviewed as the patient's condition changes — weight loss, new wounds, changes in mobility. Daily observation of skin condition by the caregiver is more important than frequent pump adjustments. If skin is showing new redness or the patient reports discomfort, call us and we will help troubleshoot settings: 866-218-0902.
Does Medicare cover therapeutic mattress systems?
Medicare may cover a Group 2 or Group 3 support surface when a physician documents medical necessity — typically for patients with Stage II or higher pressure injuries or those at documented high risk. The documentation and ordering process is specific. Call us before the physician appointment and we will walk you through exactly what is needed: 866-218-0902.
How do I clean and maintain the mattress?
Remove and machine wash the cover according to the care label. Clean air cells with a mild soap solution and warm water — never submerge or use harsh chemicals. Inspect air cells and tubing connections regularly for wear. Clean the pump filter periodically per the manufacturer's instructions. Call us if your system is not functioning as expected — we service all brands at all five Southwest Florida locations.
Can I see these mattress systems before buying?
Yes — visit any of our five Southwest Florida showrooms. Our specialists will demonstrate how the systems work, explain the differences between models, and help you choose the right level of intervention for your patient's specific situation. Walk-ins welcome: 866-218-0902.
