When someone is bedridden for days or weeks at a time, the skin is under constant stress. Pressure ulcers, sometimes called bed sores, can develop quickly and are difficult to heal. A sheepskin mattress topper is one of the practical tools carers use to help protect skin and reduce that risk. This guide explains how it works, what Australian care guidelines recommend, and how to use it well as part of a broader prevention routine.

How Pressure Ulcers Develop in Bedridden Patients
Pressure ulcers form when sustained pressure cuts off blood flow to the skin and underlying tissue. For someone who is fully bedridden, this can happen within a couple of hours on a standard mattress.
The four factors that damage skin
Pressure alone is not always the culprit. Four forces typically combine to break down skin integrity in bedridden patients:
| Factor | What it does | Common cause in bedridden patients |
|---|---|---|
| Pressure | Compresses blood vessels, starving tissue of oxygen | Lying in one position too long |
| Shear | Stretches and tears tissue layers internally | Sliding down the bed; lifting without a sliding sheet |
| Friction | Scrapes the outer skin layer | Moving across bedding; heels rubbing the mattress |
| Moisture | Softens and weakens skin | Perspiration, incontinence, wound drainage |
Where pressure ulcers are most likely to form
In bedridden patients, the highest-risk areas are bony prominences where weight concentrates. These include the sacrum (lower back), heels, hips, shoulder blades, and the back of the head. Carers and nursing staff typically check these spots first during any skin assessment.
How Sheepskin Helps with Pressure Area Management
Medical sheepskin addresses several of the four risk factors at once, which is why it has been used in Australian pressure area care for decades.
Pressure redistribution across the wool pile
The dense, upright wool fibres in a medical-grade sheepskin overlay spread the patient's weight across a wider surface area. This reduces the peak pressure at any single point, particularly over bony prominences. Australian Standard AS4480.1 specifies a minimum pile depth of 25 mm for this purpose. Overlays that meet this standard have been tested in clinical settings and shown to reduce interface pressure significantly compared to a standard mattress surface.
Moisture management and skin microclimate
Wool can absorb moisture vapour without the skin surface feeling wet. This helps maintain a healthier skin microclimate for a bedridden patient, reducing the softening effect that makes skin more vulnerable to breakdown. The fibre structure also allows air movement, which assists with temperature regulation through the night.
Reduced friction and shear at the surface
The soft wool surface reduces friction against the patient's skin during minor movements. This does not eliminate the need for proper repositioning technique, but it does lower the ongoing friction load that wears away skin integrity over time.
What the clinical evidence says
A randomised controlled trial conducted in Melbourne found that medical sheepskin reduced the incidence of pressure sores by approximately 58% compared to standard hospital mattresses. A review published in the Cochrane Database also concluded that medical sheepskin can prevent the development of pressure ulcers in hospital and residential care settings. These findings apply to overlays meeting AS4480.1, not to decorative or fashion sheepskin products.

What Australian aged care guidelines say
Australian aged care and residential facilities commonly include medical sheepskin overlays in their pressure injury prevention protocols, alongside repositioning schedules and skin assessment tools. The Wound Management Innovation Cooperative (WoundReference) and Aged Care Quality and Safety Commission guidance both recognise pressure redistribution surfaces as a core prevention strategy. Sheepskin overlays are listed as an eligible pressure care product under the NDIS and some Home Care Packages, which means funding may be available through an existing care plan.
If you are caring for someone at home and unsure whether their plan covers it, it is worth asking their care coordinator or occupational therapist to check.
What to Use Alongside a Sheepskin Overlay
A sheepskin overlay is a strong addition to a pressure care plan, but it works best as part of a routine rather than a standalone solution. No surface, however effective, removes the need for the other pillars of pressure area care.
Repositioning schedule
Regular repositioning remains the most important intervention for bedridden patients. Clinical guidelines generally recommend repositioning at least every two hours for high-risk patients, though a carer or nurse should confirm the right interval for the individual's situation. A simple written schedule, pinned near the bed, helps when multiple people share care duties.
Skin checks
Check high-risk areas at every repositioning. Look for redness that does not fade within 30 minutes of pressure being relieved. This early-stage sign (Category 1 pressure injury) is the point at which adjustments make the most difference. Catching it early avoids the more serious tissue damage that comes with Category 2 and above injuries.
Hydration and nutrition
Good skin integrity depends heavily on adequate hydration and protein intake. Dehydrated or malnourished patients are at significantly higher risk of skin breakdown. If the person in your care has a poor appetite or restricted fluid intake, it is worth raising this with their GP or a dietitian.
Heel protection
Heels are particularly vulnerable in bedridden patients because the bone sits very close to the skin surface and weight concentration is high. A sheepskin bed topper provides a protective surface, but dedicated heel protectors or pillows positioned to offload the heels entirely offer an additional layer of care, especially overnight.
Barrier creams and skin hygiene
Keep the skin clean and dry. For patients with incontinence, a moisture barrier cream applied to the perianal and inner thigh area helps protect against the softening effect of prolonged moisture exposure. Change wet bedding promptly rather than waiting for a routine linen change.

Choosing the Right Sheepskin for a Bedridden Patient
Not all sheepskin products are equal. For pressure area management in a bedridden patient, the choice of overlay matters.
Medical grade vs standard sheepskin
Look for overlays certified to Australian Standard AS4480.1. This standard specifies minimum pile depth (25 mm), wool fibre diameter (26-34 microns), and the ability to withstand high-temperature washing (up to 80°C) without losing therapeutic properties. Decorative sheepskin rugs and fashion throws do not meet this standard and are not suitable for clinical use.
Key features for bedridden use
- Velcro straps or fitted design: The overlay must stay in position when the patient is repositioned. Shifting or bunching creates pressure points rather than preventing them.
- Size suited to the bed: Choose a size that covers the patient's torso and extends to include the sacrum and hips. Single, double, and day bed sizes are typically available.
- Washable at high temperature: Infection control in a care setting requires the ability to launder at 60-80°C. Check the product's wash rating before purchasing.
Our recommendation for bedridden use
Our Sheepskin Bed Topper Overlay is made from pure Australian medical sheepskin with velcro straps to keep it firmly in place. It is available in day bed, single, and double bed sizes, and is designed specifically for people spending extended time in bed. It is a practical starting point for carers setting up a pressure area prevention routine at home.

- Medical-grade sheepskin (AS4480.1) reduces interface pressure, friction, and moisture, addressing three of the four main causes of pressure ulcers.
- Clinical evidence, including a Melbourne hospital trial and Cochrane review, supports its use as a pressure ulcer prevention surface.
- A sheepskin overlay works best alongside regular repositioning, skin checks, good hydration, and heel protection, not instead of them.
- Choose an overlay with velcro straps, a size that covers the sacrum and hips, and a high-temperature wash rating.
- If a care plan (NDIS or Home Care Package) is in place, ask whether pressure care products are covered.
