How to use a Pressure Relief Cushion

Sitting for long periods can put considerable pressure on certain areas of the body, particularly the buttocks, hips and tailbone. For wheelchair users, older adults and people with limited mobility, this sustained pressure can increase the risk of discomfort and skin damage.

A pressure relief cushion can help redistribute body weight and reduce pressure on vulnerable areas. However, knowing how to use a pressure relief cushion correctly is essential to getting the most from it.

In this guide, we'll explain how to position your cushion, use it safely, maintain it and avoid common mistakes.

How to Use a Pressure Relief Cushion: Step by Step

Although the exact instructions depend on the type of cushion, the following steps provide a useful starting point for most pressure relief seat cushions.

Step 1: Choose the Right Cushion for Your Needs

Before using a pressure relief cushion, make sure it is suitable for your body, chair and individual requirements.

Different cushions offer different levels of support. For example:

• Foam cushions provide supportive seating and may help distribute weight more evenly.

• Memory foam cushions adapt to the shape of your body to provide a more contoured seating surface.

• Gel cushions combine cushioning with materials that help distribute pressure.

• Air cushions use adjustable air chambers or cells to redistribute pressure and accommodate different seating needs.

The appropriate choice depends on factors such as body weight, mobility, sitting duration and the risk of developing pressure ulcers.

If you have an existing pressure sore, reduced sensation or a high risk of skin damage, seek advice from a healthcare professional before choosing a cushion.

Step 2: Position the Cushion Correctly on Your Chair

Correct placement is important for both comfort and pressure redistribution.

Follow these instructions:

1. Place the cushion directly on the chair or wheelchair seat.

2. Make sure it is facing the correct direction, following any labels or manufacturer instructions.

3. Position it so that it sits flat and securely on the seating surface.

4. Check that the cushion does not extend excessively beyond the edges of the seat.

5. Ensure the cover is fitted correctly and that there are no folds or wrinkles beneath you.

Some cushions feature a contoured design or a cut-out section for specific areas of the body. These must be positioned according to the manufacturer's instructions.

Important: Avoid placing extra pillows, folded towels or other padding on top of the cushion unless recommended by a healthcare professional. Additional layers can interfere with its pressure-redistributing properties.

Step 3: Sit in the Correct Position

Once the cushion is correctly positioned, sit down carefully.

For effective support:

• Position your hips towards the back of the chair.

• Keep your weight distributed as evenly as possible.

• Avoid leaning excessively to one side.

• Keep your feet supported on the floor or wheelchair footrests, where appropriate.

• Ensure your back is comfortably supported.

Good sitting posture helps the cushion work as intended and may reduce unnecessary pressure on particular areas.

If the cushion changes your sitting height, check that your feet, armrests and wheelchair positioning remain suitable.

Step 4: Adjust the Cushion if Necessary

Some pressure relief cushions are ready to use immediately, while others require adjustment.

For example, inflatable pressure relief cushions may need to be inflated to a particular level.

When using an air cushion:

1. Follow the manufacturer's instructions for initial inflation.

2. Sit on the cushion in your usual position.

3. Check and adjust the air pressure using the product's recommended method.

4. Ensure there is sufficient support without allowing your body to press through the cushion onto the seat below.

Overinflating or underinflating an air cushion can reduce its effectiveness.

Not all air cushions use the same adjustment method, so always refer to the instructions supplied with your specific model.

Step 5: Change Your Sitting Position Regularly

A pressure relief cushion is designed to help redistribute pressure, but it does not eliminate the need to move.

Remaining in the same position for extended periods can still cause pressure to build up in vulnerable areas.

If you are able to move independently, make regular changes to your sitting position. Depending on your mobility, this might involve shifting your weight, changing your posture or standing up briefly.

If you have limited movement, a healthcare professional can recommend a suitable repositioning routine and explain how a carer can assist you safely.

Remember: Even when using a specialist cushion, regular repositioning remains an important part of preventing pressure damage.

Step 6: Check Your Skin and Cushion Regularly

If you are at risk of pressure sores, inspect your skin daily, particularly around the buttocks, hips and tailbone.

Look for changes such as:

• Persistent redness or unusual discolouration.

• Areas that feel warmer or cooler than surrounding skin.

• Swelling or changes in skin texture.

• Tenderness, discomfort or pain.

• Blisters or broken skin.

Pressure damage may appear as darker or differently coloured areas rather than redness, depending on skin tone. If you notice signs of pressure damage, avoid putting further pressure on the affected area and contact a healthcare professional promptly. You should also inspect the cushion itself for damage, flattening, leaks or changes in shape that might affect its performance.

How to Use Different Types of Pressure Relief Cushions

While the general principles are similar, certain cushions require specific handling.

Cushion type	How to use it	Important consideration
Foam	Position flat on the seat and sit centrally, following its intended orientation.	Check for permanent flattening or deterioration.
Memory foam	Place the cushion correctly and allow it to conform to your seated position.	Make sure the cushion provides adequate support without bottoming out.
Gel	Position according to the manufacturer's instructions, ensuring the gel components are evenly arranged.	Inspect for leaks or damaged sections.
Air	Inflate and adjust following the manufacturer's guidance.	Check inflation and support regularly.
Coccyx cushion	Position the cut-out or recessed area as indicated by the manufacturer.	Ensure the design is appropriate for your needs and seating position.

The most suitable cushion is not necessarily the softest. It should provide appropriate pressure redistribution, stability and postural support for your circumstances.

How Long Should You Sit on a Pressure Relief Cushion?

There is no single safe sitting duration that applies to everyone.

The amount of time you can comfortably and safely remain seated depends on your mobility, skin condition, medical history and the type of cushion you use.

For example, someone who can reposition independently may have different requirements from a wheelchair user with limited sensation or movement.

A pressure relief cushion should not be treated as permission to remain seated without moving for several hours.

If you are at risk of pressure ulcers, follow an individualised repositioning schedule recommended by your healthcare professional.

Common Mistakes When Using a Pressure Relief Cushion

Even a high-quality pressure cushion may be less effective if it is used incorrectly.

Using a Cushion That Is Too Small or Too Large

A cushion that does not fit your seating surface properly may create instability or fail to support the intended areas.

Measure your chair's seat width and depth before purchasing, and compare these measurements with the manufacturer's specifications.

Placing the Cushion Backwards

Some pressure cushions have a specific front and back.

Using them in the wrong orientation can affect support and positioning, particularly when the cushion includes contours or a coccyx cut-out.

Adding Extra Padding

Putting a regular cushion or folded blanket underneath or above a specialist pressure cushion can change how pressure is distributed.

Use the cushion as designed unless a healthcare professional recommends otherwise.

Ignoring Signs of Wear

Over time, foam may lose its shape, air cushions may develop leaks and covers may become damaged.

A cushion that no longer provides its intended support may need replacing.

Assuming the Cushion Prevents All Pressure Sores

Pressure relief cushions can help reduce risk, but they are only one part of pressure care.

Regular movement, skin inspection, appropriate seating and personal care remain essential.

How to Clean and Maintain Your Pressure Relief Cushion

Regular cleaning helps maintain hygiene and may extend the cushion's useful life.

The correct cleaning method depends on its material and construction.

For most cushions, general maintenance includes:

1. Remove the cover if it is designed to be detachable.

2. Follow the washing instructions on the care label.

3. Clean the cushion's surface using the method recommended by the manufacturer.

4. Allow all components to dry thoroughly before use.

5. Inspect the cover, seams and cushioning material for damage.

Avoid machine-washing foam inserts unless the manufacturer specifically permits it.

For air cushions, regularly check valves and air cells for leaks. Gel cushions should also be inspected for signs of damage.

If your cushion has a waterproof or moisture-resistant cover, check that it remains intact, particularly if you experience incontinence.

How to Choose the Right Pressure Relief Cushion

Understanding how to use a pressure relief cushion is important, but choosing a suitable model is equally essential.

When comparing products, consider:

• Pressure relief requirements: Your risk of pressure ulcers will influence the level of support you need.

• Chair compatibility: The cushion should fit your wheelchair or chair correctly.

• Material: Foam, gel and air cushions have different characteristics.

• Body weight: Check the manufacturer's recommended user weight.

• Stability: Consider whether the cushion provides suitable postural support.

• Maintenance: Choose a design you can clean and maintain appropriately.

Frequently Asked Questions About Using Pressure Relief Cushions

Can I use a pressure relief cushion on a normal chair?

Yes, many pressure relief cushions are suitable for ordinary chairs as well as wheelchairs. However, check that the cushion fits securely and does not make the chair unstable or interfere with sitting and standing safely.

Does the textured side of a pressure relief cushion face up?

Not necessarily. Some foam cushions have a textured surface designed to face upwards, while others have a different configuration. Always check the product instructions rather than assuming which side should face up.

Do I need to inflate a pressure relief cushion every day?

Not always. Some air cushions retain their inflation for extended periods, although their pressure should be checked regularly according to the manufacturer's guidance. If your cushion is losing air frequently, inspect it for leaks or damaged valves.

Can I use a pressure relief cushion in a car?

Some pressure relief cushions are designed for use in car seats, but not all models are suitable. Check the manufacturer's recommendations and ensure the cushion does not interfere with seat belt positioning, stability or safe driving.

Can I put a cover over my pressure relief cushion?

Use the cover supplied or approved by the manufacturer. Additional covers that are too tight, thick or poorly fitted can affect pressure redistribution and may create wrinkles that increase discomfort.

Can I sleep on a pressure relief cushion?

Standard pressure relief seat cushions are generally intended for sitting, not sleeping. If you need pressure relief while lying in bed, a suitable pressure care mattress or positioning system may be more appropriate. Ask a healthcare professional for advice.
