Our bolsters have been the standard for restorative yoga teachers for over 10 years. All of our bolsters are 100% cotton (not just the cover, but the filling too). They are very firm and well crafted. Our signature large rectangle bolsters have zippers not only on the covers, but on the inner-pillow so you can adjust the firmness. They are better than bolsters that often cost nearly twice as much. They really are that good.
