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 is guaranteed to be an eye-catcher, whether in a home office or in 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 seat hardness and vertical rocking effect can be individually adjusted using air pressure regulation to suit the user's body weight.
