A heating massage cushion is a great addition to your household. It doesn't have to be used only for babies and small children. The cover is made from 100% cotton and is zipless. Even though they are filled with buckwheat hulls, they are machine washable at 40 °C. To heat them up use a microwave oven, radiators or just leave them in the sunshine. Use them to relieve pain in joints, cervical spine, shoulders, back, head, but also for stomach pains or period pains. Buckwheat hulls maintain and transfer heat. However, the cushion can also be cooled down in the fridge and then it helps bring down temperature or relieve pain caused by burns.
