For those concerned with sore knees and ankles when meditating try the Zafu and Zabuton together.
The Zabuton protects the knees and feet on hard surfaces and insulates the body from cold surfaces when meditating. Covered with a tight fitting zippered outer made from durable 100% cotton drill which in turn is tufted in place, the zabuton will last for years as you can both refill the inner cushion and if the cover becomes soiled it can be removed and washed or replaced by simply cutting the centre tuft (Size: 91cm x 71cm x 6cm). The Zafu is perfectly used for Zen meditation. It is ideal for lotus or half-lotus meditation postures and is the most versatile size of cushion supporting a variety of postures. There is a hidden zip that allows you to add or remove to the filling to adjust the loft or the softness to suit you. Pleated for extra durability and filled with natural buckwheat hulls. The cushion also has a convenient handle for easy carrying (Size : 18cm x 35cm)
