A yoga bolster is used to provide comfortable yet firm support in a variety of yoga asanas and to prevent strain from overstretching. They are typically used in restorative yoga and meditation to help maintain form and bear weight for poses that are held for several minutes. As well as to bolster yoga asanas, they can also be used as a general cushion or pillow, or for physiotherapy. The Buckwheat Yoga Bolster is our best-selling bolster — used in studios across the UK and worldwide. This round yoga bolster is of standard size, filled with eco-friendly buckwheat hulls, and has a convenient carry handle.
