Coccyx cushion (also known as coccydynia cushion) help to reduce pressure on your back or tailbone while sitting for extended periods. Before you buy it, make sure that a coccyx seat cushion:
- is made from a 100% memory foam with no additives,
- is a U-shaped ergonomic design, this design help reduce the pressure on your inflamed or bruised tailbone,
- cover is machine washable,
- base is non-slip, this ensures minimal movements and prevents having to constantly adjust the cushion,
- built-in handle so that its easy to be carried,
- price. If you trust the brand, the price probably does not matter. The exception lies with therapeutic cushions designs for a specific purpose (like seat cushions to also provide relief for orthopaedic condition). https://www.nhs.uk/conditions/tailbone-pain-coccydynia/treatment/
