Pressure injuries — sometimes called pressure sores or bedsores — are among the most preventable and most serious harms in care, yet they develop quietly wherever mobility, sensation, nutrition and time in one position combine unfavourably. The instinct is often to buy a "pressure mattress" and consider the problem solved. It is not. Equipment is one component of a documented prevention and care plan led by clinical assessment. This guide explains how the risk works, how to choose surfaces sensibly, and why repositioning and skin checks remain essential no matter what you buy.
The message throughout is simple and non-negotiable: pressure care equipment supports a plan; it never replaces one. A mattress or cushion cannot see a reddened heel, turn a person, improve their nutrition or notice deterioration. People do that, guided by assessment.
Where this sits — the Care Environment Framework: Safety. This article applies CareAid's Safe Environment Model — Person → Task → Equipment → Environment → Review — where the surface is only the Equipment factor, and Review (repositioning, skin checks, escalation) is what actually keeps skin intact.
Understand what drives the risk
Pressure injury risk is not the same for everyone, and it changes over time. It depends on a combination of factors:
- Mobility — how much the person moves and repositions themselves independently
- Sensation — whether they can feel and respond to discomfort or pressure
- Skin condition — fragility, existing damage and integrity
- Nutrition and hydration — which affect skin resilience and healing
- Moisture — from incontinence or perspiration, which weakens skin
- General health — circulation, chronic conditions and acute illness
- Time in one position — the longer the load, the greater the risk
Because these interact and shift, a formal clinical pressure-risk assessment is the right starting point. It determines the level of risk and the category of surface and support required — not a product description or a sales claim.
Choosing a support surface
Support surfaces broadly fall into categories suited to different risk profiles. Use this as an orientation, then follow the clinical assessment:
- If the person is at lower risk with good mobility → a quality foam or hybrid surface may be appropriate as part of the plan.
- If risk is higher, or an injury is present → a powered alternating-pressure system may be indicated, chosen against the clinical assessment.
- If the person sits for long periods → a properly selected pressure-relieving cushion matters as much as the mattress; seated pressure is easily overlooked.
- If weight is outside standard ranges → confirm the surface is rated for the user's weight; too heavy or too light can both reduce effectiveness.
- If needs are changing or unclear → reassess with a nurse or occupational therapist rather than assuming the current surface still fits.
What to verify before you buy a mattress or cushion
Whatever category is indicated, confirm the practical details:
A powered surface in particular requires staff who understand its settings and alarms. Equipment that is set wrong, or whose alarm is ignored, offers less protection than a simpler surface used correctly.
Equipment does not replace repositioning or skin checks
This point deserves its own heading because it is where harm most often creeps in. Never imply, or allow anyone to assume, that a mattress or cushion removes the need for repositioning, skin inspection or clinical review. A support surface reduces and redistributes pressure; it does not eliminate the need to change position, keep skin clean and dry, maintain nutrition and hydration, and inspect at-risk areas regularly.
A robust plan documents who repositions the person and how often, how and when skin is checked, nutrition and moisture management, the equipment in use, and how deterioration is escalated. The equipment sits inside that plan — it is not a substitute for any part of it. In the Safe Environment Model this is the Review factor doing the heavy lifting: the surface's safe working load, weight rating and ARTG status are confirmed once at selection, but repositioning and skin inspection are the ongoing checks that make it safe over time.
Document, monitor and escalate
Good pressure care is a governance issue as much as a product one. Record the risk assessment, the plan, the equipment in use, and the monitoring schedule. Note who is responsible for repositioning and skin checks, and how any early skin change is escalated to a nurse or clinician. For residential aged care providers, this documentation also supports quality and safety obligations and links directly to incident learning when something goes wrong. Review the plan and the equipment at scheduled intervals and after any change in the person's condition.
Funding in Australia
Pressure care equipment may be funded through several pathways. Under the NDIS, assistive technology can be funded where reasonable and necessary and supported by assessment. Older Australians may access the Support at Home program's Assistive Technology and Home Modifications (AT-HM) pathway, and residential providers procure within their own quality and safety obligations. Funding and evidence requirements change, so confirm current eligibility before purchase and keep the clinical assessment that justifies the surface.
Frequently asked questions
Does a pressure mattress mean we can stop repositioning? No. A support surface reduces pressure but never removes the need to reposition, keep skin clean and dry, maintain nutrition and hydration, and inspect the skin. Repositioning remains part of the plan.
How do I know which pressure mattress to choose? Start with a clinical pressure-risk assessment. It determines the risk level and the category of surface — foam, hybrid or powered alternating — appropriate for the person. Match the product to that assessment, not to marketing claims.
What happens to a powered mattress in a power failure? It depends on the product. Confirm the power-failure behaviour and any backup before buying, and make sure staff know what to do so the person is not left unsupported.
Are cushions as important as mattresses? For anyone who sits for long periods, yes. Seated pressure is easily overlooked, and a properly selected pressure-relieving cushion is an important part of the plan alongside the mattress.
Build pressure care on solid foundations
CareAid Supplies stocks foam, hybrid and powered pressure mattresses and cushions suited to Australian homes and providers, chosen to fit a clinical assessment rather than a sales pitch. Start with the pressure-risk assessment, build the plan around it, and let our range provide the right surface for the person.
