Spending a lot of time sitting? Whether you use a wheelchair or a supportive chair for extended periods, it’s important to understand the risks of pressure ulcers — and how to prevent them. This easy-to-read guide, part of the Get Wise series from the British Healthcare Trades Association (BHTA), is designed for everyday users and carers, offering practical advice to stay safe and comfortable.
What Are Pressure Ulcers?
Pressure ulcers (also known as bedsores or pressure sores) are areas of damaged skin and tissue caused by prolonged pressure or friction. They develop when the skin and soft tissues are squeezed between a bone and a surface — like a chair or wheelchair seat — for too long without relief.
You don’t have to be ill to get one — anyone is potentially at risk.
Common Risk Factors Include:
- Age or reduced mobility
- Medical conditions such as diabetes or poor circulation
- Nutritional deficiencies
- Certain medications
- Continence issues
- Inappropriate seating or support surfaces
- Moisture and temperature
Why Sitting Posture Matters
Even when sitting upright in a stable chair, pressure isn’t distributed evenly across the body. Here’s a general breakdown:
- 75% through the buttocks and thighs
- 19% through the feet
- 4% through the backrest
- 2% through arm supports
This means the majority of pressure is concentrated under the seated area — exactly where ulcers are most likely to form. Poor posture can increase that pressure even more, especially if you lean or sit unevenly.
That’s why posture, seating, and pressure relief work hand-in-hand to protect your skin and keep you comfortable.
Who’s Most at Risk?
Some people are more vulnerable to developing pressure ulcers, particularly if they experience:
- Neurological conditions affecting movement
- Limited or no active movement
- Postural challenges or changes in body shape or weight
- Reduced sensory awareness (less able to feel pain or discomfort)
- Communication difficulties (unable to tell someone when uncomfortable)
Early Warning Signs to Watch For
- Skin that’s discoloured and doesn’t lighten when pressed
- Warm, firm, or spongy patches of skin
- Pain, itchiness, or unusual sensations in one area
- Red or purple marks (on lighter skin) or bluish/purplish tones (on darker skin)
If untreated, a pressure ulcer can progress from mild surface damage to deep wounds reaching muscles or even bone — which is why early detection and prevention are vital.
How Pressure Ulcers Affect Your Life
Pressure ulcers can have a serious impact on your wellbeing:
- Physically: Pain, infection, and reduced mobility
- Emotionally: Lower confidence and independence
- Financially: Extra care costs or equipment
- Psychologically: They can be distressing and isolating
That’s why prevention is always better than cure.
How to Reduce the Risk
- Choose the right seat or wheelchair: Use pressure-relieving cushions and ensure proper sizing.
- Move regularly: Even small shifts in position relieve pressure and encourage circulation.
- Reposition often: Follow a regular routine if you can’t move independently.
- Check your skin daily: Or ask a carer to help spot early warning signs.
- Stay hydrated and nourished: Good nutrition helps maintain healthy skin.
- Get professional advice: Speak to a BHTA-accredited supplier for expert seating support.
