When do you choose this product?
When should you use a sit-stand stool?
A sit-stand stool such as the Topstar Sitness H1 is ideal when your workspace is not fully height-adjustable, or when you want to add a dynamic sitting experience to your existing desk. This type of stool works perfectly as a complement to a sit-stand workstation or when you regularly switch between different working postures.
Why choose these compact dimensions?
With seat dimensions of 350×350 mm, this stool offers a compact seating surface that saves space and is flexible to use. The triangular shape ensures a stable seating position without taking up much room. The swivel function lets you easily change direction without moving the stool.
Benefits of the 3-dimensional movement
What makes this stool special is the 3-dimensional mobility that activates your core muscles while sitting. This encourages an active sitting posture and can help strengthen your back muscles. The TPU sole provides grip and stability, while still giving you the freedom to move.
Practical height adjustment
The stepless height adjustment of 570-770 mm makes this stool suitable for most desks and body heights. With a load capacity of 110 kg, it is sturdy enough for intensive use. The lever under the seat allows easy height adjustment, even while seated. The black-lacquered gas spring guarantees a long service life.
