1. Perfectly conforms to the body. Other balance pillows are often stiff and uncomfortable, and they will leak air or become permanently deformed after a short period of time. However, our bump massage pillow is made of a material that is both flexible and durable and stable. It can perfectly 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. Relieves spinal pressure. Thanks to the flexible structure of the balance cushion, you can transform any office chair into an ergonomic exercise ball and enjoy a comfortable and energetic sitting experience at any time. This keeps the spine active, and back pain and tension will be a thing of the past. In addition, you can easily and flexibly adjust the hardness according to your personal needs using the included air pump. 3. Effectively conducts strength and balance training.
