Choosing a Pressure Relieving Cushion for Home Use

Why the right cushion matters for pressure ulcer prevention

If you or someone you care for spends long periods sitting – in an armchair, a wheelchair or a recliner – the points where the body meets the seat are under constant pressure. The sitting bones (ischial tuberosities) and the coccyx at the base of the spine take the brunt. Without relief, that pressure can reduce blood flow to the skin and underlying tissue, and a pressure ulcer can begin. A suitable cushion is not a luxury; it is a core part of pressure care at home. Families and carers often ask which cushion to choose. There is no single answer, but understanding the main types helps you have a more productive conversation with a clinician.

Foam, gel and air: how they relieve pressure

Pressure relieving cushions work by spreading load, reducing peak pressure, or alternating pressure. The three main families are foam, gel and air.

• Foam cushions are lightweight and affordable. Moulded or memory foam conforms to the shape of the sitting bones. They suit people at lower risk who can still shift their weight. However, foam can compress over time, hold heat and bottom out under heavier users.
• Gel cushions contain a viscous gel or gel bladder that flows away from pressure points. They tend to feel cooler than foam and offer good stability for moderate risk. They are heavier, and the gel can leak if the cover is damaged.
• Air cushions use inflatable cells, sometimes with an alternating pump that cycles pressure. They are often recommended for higher risk or for people who cannot reposition themselves. They need regular inflation checks, and punctures are possible.

Hybrid cushions combine materials – for example, foam with gel or air – to balance comfort, stability and pressure relief. Your clinician can explain which approach fits the person’s risk level.

What to look for in a home cushion

Practical details make a big difference when you are caring for someone day to day. Check these features before you buy or accept a loan.

• Cover: a two-way stretch, vapour-permeable and waterproof cover helps keep skin dry and reduces shear and friction. It should be washable.
• Stability: a non-slip base stops the cushion sliding. Avoid cushions so thick that transfers in and out of the chair become unsafe.
• Weight and height limits: every cushion has a maximum user weight. Also check the cushion height – too tall can affect foot clearance and posture.
• Maintenance: foam needs no pump; air cushions need regular inflation checks; gel needs checking for leaks.
• Comfort and temperature: breathable fabrics help. Gel may feel cooler, while air can feel firmer until adjusted.

Matching the cushion to the person and their routine

The right choice depends on mobility, risk level, posture and where the person sits. A formal risk assessment – such as the Waterlow or Braden scale – helps guide this. As a general guide:

• Low risk, mobile: a good quality foam or gel cushion may be enough, especially if the person can shift position every 15 to 30 minutes.
• Moderate risk, some mobility: gel or a hybrid cushion often works well, offering pressure relief and stability.
• High risk, limited mobility: an air or alternating air cushion is usually more appropriate. These are also useful for people who cannot feel or report discomfort.

Consider posture too. If the person slides forward, a wedge or contoured cushion can help. If they use a wheelchair, the cushion must fit the wheelchair seat precisely. For an armchair, measure the seat before choosing.

Using and caring for the cushion day to day

No cushion replaces regular repositioning. Encourage or assist with weight shifts every 15 to 30 minutes if possible. Check the skin at least twice daily, paying attention to the sitting bones, coccyx, heels and any area that looks red. Use a mirror to see hard-to-reach places. Redness that does not blanch when pressed needs urgent review.

• Set reminders for repositioning, especially during long periods of sitting.
• Keep the cushion clean and dry, following the manufacturer’s instructions.
• For air cushions, check inflation pressure regularly – over- or under-inflation reduces effectiveness.
• Inspect foam for flattening, gel for leaks and air cells for punctures. Replace damaged cushions promptly.
• Make sure the cushion is the right way round; many have a front and back.

Working with a clinician to compare options

Before you buy, ask for a seating assessment. In the UK, you can speak to your GP, district nurse, occupational therapist or tissue viability nurse. They can assess risk, posture and your home setup, and may recommend a specific type. Some cushions are available through NHS wheelchair services or community equipment loans, so it is worth asking. A clinician can also help you trial different options – what works for one person may not suit another. If you are self-funding, ask about returns and trial periods. Pressure mapping, where available, can show how well a cushion offloads the sitting bones. The right cushion, combined with good repositioning and skin care, can prevent pressure ulcers and improve comfort. Review your choice if the person’s condition or mobility changes.
