Active sitting has never been easier with this sitting ball! The saddle shape and 360-degree swivel keep you in motion, while the height adjustment ensures a perfect working posture.
When do you choose this product?
When should you choose a saddle-shaped ergonomic ball?
This ergonomic ball combines the benefits of dynamic sitting with the ergonomic saddle shape. Thanks to the saddle shape, you automatically sit in a more upright posture, which brings your pelvis into the correct position and allows your spine to curve naturally. This type of ball is ideal if you work regularly at a desk and want to improve your posture without switching to a traditional office chair.
Why this specific variant with height adjustment?
The integrated height adjustment makes this model suitable for different desks and body heights. You can adjust the seat height between 530 and 640 mm, so you can always find the right working posture. The built-in spring mechanism in the base provides extra dynamism while sitting, while the 360-degree rotating seat gives you freedom of movement.
Practical features for everyday use
With a load capacity of 110 kg, this ball is suitable for most users. The polyester material with comfortable padding ensures a pleasant seating experience. The integrated carrying handle makes it easy to move the ball when you change workstations.
Tip for optimal use
The specially shaped base is designed for sideways movements, so you don't need to worry about the ball rolling away during small body movements. This ergonomic ball is recommended for sitting periods of up to 4 hours per day.
