The Sitness 5 is a versatile fitness stool. The integrated exercise ball not only provides an alternative for active sitting but also gives it a unique shape that serves as an eye-catcher, whether in a home office or a lounge or waiting area. The integrated exercise ball, covered with 70% wool, 25% polyamide, and 5% other fibers, ensures three-dimensional mobility of the seating surface. The seating firmness and vertical rocking effect can be individually adjusted to the corresponding body weight using air pressure regulation.
