However, our bump massage pillow is made of a material that is flexible, durable, and stable. It can conform to your body without deformation or air leakage. It has two sides, one with bumps and the other smooth, allowing you to adjust the comfort level according to your personal needs. 2. It relieves spinal pressure. Thanks to the flexible structure of the balance cushion, you can turn any office chair into something like an exercise ball and enjoy a comfortable and energetic sitting experience at any time.
