💡 Overview

Pressure care mattresses are an essential part of clinical bed setups for clients at risk of skin breakdown, pain, or prolonged immobility. They’re used across a variety of settings—from home care and hospitals to residential aged care—to reduce the risk of pressure injuries and support healing.

Mattresses in this category range from basic foam pressure-relief surfaces to high-end dynamic alternating air systems. The right choice depends on the client's risk profile, mobility level, continence status, and comfort needs. Selecting the wrong surface can lead to complications like bedsores, increased pain, or hospital admissions.

Occupational therapists and clinical staff often prescribe therapeutic mattresses in conjunction with height-adjustable beds, positioning supports, and mobility aids to promote independence, pressure redistribution, and safer transfers. Understanding the different types and features available is critical to matching the right surface to the client’s needs.

🤔 Did You Know?

Pressure injuries can begin forming in as little as 2 hours of immobility. Using the correct therapeutic mattress is one of the most effective ways to reduce this risk—especially in aged care, post-operative recovery, and palliative settings.

🛍️ Sales FAQ

What’s the difference between a hospital mattress and a regular mattress?

Hospital mattresses are designed to reduce pressure, improve hygiene, and fit adjustable beds. They often include clinical features like waterproof covers, contoured zones, or alternating air cells—none of which are found in standard home mattresses.

Can these mattresses be used on a normal bed?

Some foam pressure care mattresses may work on flat domestic bases, but most require an adjustable bed frame for full effectiveness—especially hybrid or alternating systems. Compatibility should always be checked at time of sale.

Do pressure care mattresses feel uncomfortable or “medical”?

Not at all. Many modern pressure care surfaces are made with comfort in mind. Some models even have soft top layers or memory foam for a familiar feel while still offering therapeutic support.

What’s the weight limit for these mattresses?

Weight limits vary. Standard models typically support up to 120 kg, while bariatric versions can accommodate 150–300 kg. Always check the specification sheet to ensure a safe match for the user.

Can I use a mattress protector on top?

Yes—but it must be breathable and not interfere with the function of the pressure care surface. Avoid plastic or non-permeable protectors unless clinically required. Many mattresses already include waterproof covers.

What’s the clinical difference between static foam and alternating air mattresses?

Static foam redistributes pressure by contouring to the body and spreading load over time. Alternating air mattresses actively cycle inflation between cells to offload pressure from one area at a time—ideal for clients who can’t reposition independently or have existing pressure injuries.

Can I use an alternating air mattress without a pump or electricity?

No—alternating systems rely on a powered pump to maintain the airflow cycle. Without it, the mattress defaults to a static air mode and loses its dynamic pressure-relief functionality. In those cases, consider a non-powered static air overlay instead.

Why is this mattress more expensive than a memory foam one from a retail store?

Retail mattresses are designed for comfort, not clinical use. Clinical mattresses are built to meet infection control standards, reduce the risk of pressure injuries, support medical conditions, and integrate with height-adjustable beds. They also undergo rigorous safety and durability testing.

Can this mattress be used for a client with incontinence issues?

Yes. Most pressure care mattresses include a waterproof, vapour-permeable cover that prevents fluid penetration while allowing the skin to breathe. However, persistent exposure may still degrade the foam—continence management plans are essential.

Does the mattress come with a clinical risk rating?

Yes—mattresses are often rated for low, medium, high, or very high risk of pressure injury. These ratings are based on clinical guidelines (e.g., Waterlow or Braden scales). Always match the mattress rating with the client's clinical profile or OT recommendation.

Is this mattress compatible with side rails or profiling beds?

Yes, most clinical mattresses are designed to work with hospital-style profiling beds and side rails. However, ensure the mattress depth matches the side rail clearance to prevent entrapment. We can advise on safe combinations.

Common Customer Questions

Can I use this mattress on my current bed frame?

It depends on the mattress type. Foam mattresses may be used on flat frames, but alternating air and hybrid systems often require adjustable profiling beds to function correctly and safely.

How long will the mattress last?

Pressure care mattresses generally last 3–5 years with normal use. Lifespan can vary depending on user weight, care routines, and exposure to moisture or incontinence. Alternating systems may need earlier servicing or pump replacement.

Is this mattress noisy?

Foam and hybrid mattresses are silent. Alternating air mattresses use a low-noise pump, which produces a gentle hum. Most users find it unobtrusive, especially with newer, quieter models.

Will the mattress get hot at night?

No. Most pressure care mattresses are designed with breathable covers to minimise heat and moisture build-up. Low-air-loss systems provide active airflow for temperature control and skin health.

How do I clean and maintain this mattress?

Wipe-down waterproof covers are standard. Some may be machine-washable. Avoid soaking foam cores. Alternating air systems require pump filter checks and regular inspection for leaks or airflow issues.

Why does my mattress feel uneven or sag in the middle?

This could be a sign of foam fatigue, pump failure (in air systems), or incorrect bed base support. If the mattress doesn’t return to shape or feels collapsed under pressure points, it may need replacement.

Can I put a sheepskin or mattress topper over this?

Only if approved by a clinician. Additional layers may interfere with pressure redistribution—especially on air systems. Some comfort layers are compatible, but clinical advice is recommended.

Do I still need to reposition the person using this mattress?

Yes. Even advanced pressure care mattresses don't eliminate the need for repositioning, especially for high-risk users. Repositioning schedules are still required to prevent pressure injury development.

What’s the risk if a mattress is too soft for the user’s needs?

Overly soft mattresses may cause poor posture, increased shear, and lack of pressure redistribution—raising the risk of pressure injuries. Firmness and envelopment must be balanced for clinical outcomes.

Can this mattress be used with a profiling (electric) bed?

Yes, most pressure care mattresses are designed to flex with profiling beds. However, alternating air systems must be carefully matched to avoid bending air hoses or disrupting pressure cycles.

Will this mattress prevent pressure injuries entirely?

No. Mattresses reduce risk but don’t eliminate it. Skin care, nutrition, hydration, and repositioning are all still essential parts of a full pressure care plan.

What should I do if I notice ‘bottoming out’?

‘Bottoming out’ means the user is sinking through the mattress and contacting the bed base, which defeats the pressure care function. This requires immediate action—either replacing the mattress or reassessing needs.

How often should an alternating air mattress be checked or serviced?

Every 6–12 months. Pumps, hoses, and pressure settings should be reviewed to ensure function and safety. Filters may need cleaning or replacement to maintain proper airflow.

Can this mattress support bariatric clients at risk of pressure injury?

Only bariatric-rated models should be used for clients over 120–150 kg. Look for reinforced cores or heavy-duty air systems designed to safely distribute weight and prevent bottoming out.

Is alternating air suitable for clients with dementia or agitation?

It can be, but consider pump noise and mattress movement. Some clients may find the sensation confusing or uncomfortable. Hybrid or quiet static systems may be more appropriate in some cases.

Why is matching the risk level so important?

Using a mattress below the user’s pressure injury risk level can result in inadequate support. Always use clinical guidelines or an OT assessment to match mattress risk rating to the client’s needs.
