Discover the concept

The ActiveBase ergonomic stool is equipped with a double adjustable mobility system: one is located under the seat and the other is located at the base of the stool.

Thanks to this double mobility, you can choose to work only the pelvis or the lower limbs. Or both, depending on your preferences.

This dual functionality is adjustable, making the ActiveBase suitable for all possible body sizes.

Effective from the first use

By instantly repositioning the spine, the ActiveBase desk stool acts directly to improve blood circulation. While naturally correcting the posture.

The ActiveBase ergonomic stool actively supports the abdominal muscles in the sitting position by stimulating the deep muscles via the seat angle. A great way to stay active while sitting.

A perfect tool for good teleworking

Even occasional use of this ergonomic stool prevents MSDs (musculoskeletal disorders) and helps to avoid the static effect of the sitting posture which causes more than 90% of back pain.
