The YogaAccessories Deluxe Bolsters are the heaviest bolster available! Weighing a full 9 pounds, these extra dense bolsters are the perfect support for a number of yoga poses. Your yoga bolster should be firm enough to help you tackle those more challenging poses, and these deluxe bolsters will help you reach further and safer. Place one under the back, shoulders, and head to help open up the chest and lengthen the spine. Use one in seating poses to prevent clenching of the abdominals during forward bends. Made with 100% natural cotton, you will find that they are firm enough to provide full support, yet soft enough to be quite comfortable. The Deluxe Round Cotton Yoga Bolster is 28” long, 10” in diameter, has a zippered opening to remove filling for height adjustment, and only from YogaAccessories!
