A bolster supports the body when you are performing complex poses. The prop is particularly helpful for beginners and those with limited mobility as it provides additional support throughout each posture. It’s not uncommon for complicated poses to be tricky, and sometimes even painful, to achieve. A yoga bolster helps to ease the pain by providing the body with correct alignment throughout. The prop can be used in a variety of different positions with some of the most popular being below the knees, hips, neck, and legs.
