MALLOW Balance Ball Knit Pistachio

An oval balance ball that allows you to exercise while working. It supports your sitting posture flexibly as you move, stimulating your abdominal muscles and core, making it an excellent choice for a desk chair if you tend to be sedentary. The fun bouncy and wobbly seating experience allows you to stretch your back, abdomen, sides, and shoulders by turning sideways, providing an easy way to refresh your body. The oval shape is narrower and more compact than a spherical balance ball, taking up less space. It's the new standard in balance balls, featuring a moderate level of stability and smart design that allows it to stand on its own.Source：https://www.amazon.co.jp/
