Stay in motion while sitting with this ergonomic sitting stool! The flexible TPU element provides a natural rocking motion, while you effortlessly adjust the height between 440 and 570 mm.
When do you choose this product?
What is a sit-stool and when do you need one?
The Sitness Bob is a freestanding sit-stool for dynamic and active sitting. This product is ideal for home offices and short sitting periods (max. 4 hours), where you want to combine freedom of movement with ergonomic comfort.
Why choose this adjustable model?
With an adjustable height range of 440 to 570 mm, this sit-stool offers plenty of flexibility. You can adjust the height steplessly thanks to the chrome-plated gas spring, so you can always find the perfect ergonomic seated position. The round seat surface with a diameter of 365 mm offers comfortable seating.
Unique movement feature for active sitting
What sets this model apart is the moving TPU element, which provides a horizontal rocking effect. This means you can gently move while you work, which activates your core muscles and breaks up static sitting. The aluminium design base gives the whole piece a modern look and ensures stability.
Practical considerations when using it
Please note that this product is suitable for users up to 110 kg. The polyester upholstery is practical because it is easy to keep clean. Make sure the sit-stool stands on a stable surface for optimal safety. Thanks to the chrome-plated finish, the product fits well in modern office environments.
