Quick answer: A pressure relief cushion spreads your weight so less of it sits on the bony points under your bottom. Foam and memory foam cushions suit most people who sit for a few hours a day and can shift their weight. Gel and air-cell cushions give more protection for people who sit for long periods or have had pressure damage before. If you already have a red mark that does not fade, broken skin, or you cannot feel or move well, do not choose a cushion on your own: ask your GP, district nurse or wheelchair service for an assessment, because the NHS provides pressure-relieving cushions where there is a clinical need.

These cushions are sold through Amazon UK, with live prices and stock from the retailer. Check each cushion’s size against your wheelchair seat before ordering, because a cushion that overhangs or leaves gaps does not work properly.

Types of pressure relief cushion
Foam and memory foam
The most common and least expensive type. Shaped or castellated foam, cut into blocks, spreads load better than a flat slab. Foam wears out and flattens with use, so it needs replacing more often than other types.
Gel
Gel moves with you and helps with shear, the dragging force on the skin when you slide or shift. Gel cushions are heavier, and the gel can migrate over time, so they need checking and kneading back into place.
Air cell
Interconnected air cells give the most even support and are often used for people at high risk. They must be inflated correctly: too firm and they act like a hard seat, too soft and you sink through to the base.
How to choose
- Size: match the cushion to the seat width and depth of your wheelchair. Measure the seat, not the old cushion.
- Height: a thick cushion raises you in the chair, which changes how you reach the wheels, footplates and table tops.
- Cover: look for a breathable, water-resistant cover that can be removed and washed, with a non-slip base.
- Stability: a soft cushion can make transfers harder. If you move in and out of the chair on your own, try the cushion before relying on it.
- Avoid ring or doughnut cushions for pressure relief. They are generally advised against because they can concentrate pressure around the ring.
A cushion is only part of pressure care
- Change position regularly. Even the best cushion does not replace shifting your weight or standing where you can.
- Check your skin every day, or ask someone to, especially over the base of the spine, the buttocks and the hips.
- Check the cushion is not worn out. With you seated, slide a flat hand under the cushion beneath your seat bones. If you can feel very little cushion between your hand and your body, it has bottomed out and needs adjusting or replacing.
- Seek help quickly if a red or dark patch does not fade after you take the pressure off.
Ways to pay less
- If you are at risk of pressure ulcers, ask your GP, district nurse or wheelchair service whether a cushion can be provided on the NHS.
- Cushions designed for disabled people can be bought without VAT by someone with a disability or long-term illness. See our VAT relief guide.

Frequently asked questions
What is the best type of cushion for pressure relief?
It depends on your risk. Foam or memory foam suits people at lower risk who can move easily. Gel and air-cell cushions give more protection for people who sit for long periods or have had pressure damage. A clinician can advise on the right level.
How often should a wheelchair cushion be replaced?
Follow the manufacturer’s guidance, but check it regularly. Foam cushions flatten with use and may need replacing within a year or two of daily use. Replace any cushion that has bottomed out, split or lost its shape.
Can I get a pressure relief cushion on the NHS?
Yes, if you are assessed as needing one. Ask your GP, district nurse or the wheelchair service. They can also check you are using the right type.
Do I still need to move if I use a pressure cushion?
Yes. A cushion reduces pressure but does not remove it. Regular changes of position are still one of the most important ways to prevent pressure ulcers.
Why are ring cushions not recommended?
A ring or doughnut cushion can press on the skin around the hole and reduce blood flow to the area in the middle, so they are generally advised against for preventing pressure ulcers.
