Donut ring cushions are designed to provide comfort to those who spend an extended time sitting. The cushion's unique shape helps to distribute weight evenly and reduce pressure on the lower back and tailbone. This can be particularly helpful for people who suffer from back pain or have recently undergone surgery. Donut ring cushions can also be conveniently placed on wheelchairs to provide additional comfort. We are a UK seller and always get your item in the post ASAP Thanks for looking
