These firm booster cushions are covered (on top) in a pure wool fleece. So it’s the wool removed from a sheepskin. The unique properties of sheep’s wool allow the skin to breathe while cushioning the body and helping to regulate body temperature, offering year-round comfort. Sheep’s wool is known for its health benefits being hypoallergenic, naturally water-resistant, and fire retardant. We’d recommend it as a good firm square booster for any chair – it’s also excellent for wheelchairs.
The cushions have a pure wool pile on the upper and front edge, the bits that matter, with a vinyl underside. The zipped cover can be removed for washing (wool wash- leave to air dry). They wash really well- we’ve tried.
