When do you choose this product?
What is a saddle stool and when do you need one?
A saddle-shaped stool is designed for active sitting, where you change position regularly. Its specific shape keeps you in a more upright posture, which promotes circulation and activates your core muscles. This type of seating is ideal for workplaces where you alternate between sitting and standing, or as an alternative to a traditional office chair.
Why choose the 360° swivel model?
The full swivel action makes this model particularly suitable for workplaces where you need to reach in different directions from your seated position. You turn effortlessly without having to twist your body, which prevents tension in your back and neck. This makes it easy to move the stool between different work locations.
Height adjustment for ergonomic comfort
With an adjustable range of 530 to 640 mm, this stool suits different body heights and table or desk heights. The saddle shape encourages a natural, upright sitting posture in which your pelvis is positioned correctly. The padded upholstery provides sufficient seating comfort for regular use.
Practical considerations for use
The stable aluminium base with double safety castors and a load capacity of 110 kg makes this stool suitable for intensive use. The castors are specifically designed for carpeted floors, so check whether this suits your type of flooring. For hard floors, you may need different castor types to prevent scratches.
