Pressure relief cushions are a valuable aid in the prevention of ulcers, which can be very painful as well as difficult to treat. People with low mobility, who spend lots of time in the same position, are at risk of developing sores, especially on bonier parts of their bodies, which press against their beds or chairs. Buttocks, shoulders and hips are the most commonly affected areas, as well as heels, which are sometimes damaged by friction against sheets.

Before purchasing any type of medical equipment it is wise to speak to a professional. Physiotherapists and occupational therapists are likely to have the greatest knowledge of these products and can help on choosing the most suitable. Not only can buying the incorrect item be a waste of money, it can also be dangerous as for example, putting too high a cushion in a wheelchair could put the patient at risk of falling out of it.

Not all pads will meet the requirements of every user. People who find it difficult to get up out of a chair will benefit from a firmer pad that will be unlikely to slip in the chair when they try to move. Other people will prefer memory foam, which moulds to the shape of their body and feel very comfortable.

Sores and ulcers are more likely to develop when skin is damp, so a pad that wicks moisture away from the body is a good idea, especially for people who tend to get hot easily, or the incontinent. Waterproof items are available for the incontinent, but can also be useful for others, for example if drinks are spilt. All patients would benefit from a product that can be cleaned as this should extend the life of the item.

Some products feel warmer t the touch than others depending on whether they contain foam, water, gel or air. Gel pads generally feel the coldest so somebody who feels the cold may not be comfortable sitting on one. Foam usually feels warmest and gets warm from the heat of the body quite quickly so is best avoided by those prone to overheating.

As well as being manufactured in different sizes and shaped, some products are available with a ramp to one side, which can be very useful for patients with low stability as they can help keep them in their chairs. Different pads are suitable for those at differing risks of ulcers. These items will last longer if they are turned regularly, and very, thin soft pads that will wear out quickly are of little use.

All products should adhere to fire safety laws but smokers should take particular care that the pad they use is fire resistant. Very heavy patients may need to check that the product they are considering will take their weight and obviously, children will have different needs to adults. If the item will need to be moved around it should not be too heavy or hard to grip.

There are lots of ways to help prevent the development of ulcers, including taking care to move the patient using the correct technique and apparatus. People at risk should be fed a healthy diet and drink enough, as well as not spending too long in too hot or too cold conditions. Pressure relief cushions can also help prevent sores developing as well as making the patient more comfortable.
