Give your knees a break with this set of Triangle Knee cushions. If your knees cramp or fall asleep when you meditate, it maybe that they need a little lift! Our Triangle Knee Cushions help you meditate comfortably by lifting and supporting the knees. Some people need a little lift and others need more, so we make our cushions in different heights and seizes. They are stuffed with buckwheat hulls to make them malleable and comfy.
