Sitness is a modern brand from Topstar GmbH that stands for inspiring and sustainable seating solutions. Our unique technology for dynamic sitting has been developed to achieve a beneficial effect on health. With market expertise and modern product developments, Sitness is increasingly differentiating itself into a lifestyle brand with products ranging from children’s chairs to office chairs, gaming chairs and the new dining room collection.

Sitness combines movement and design

Everyone spends over 10 hours a day in a sitting position. This is a lot of time that should definitely not be spent sitting on bad chairs – because this leads to poor posture and back pain. The moving Sitness technology activates and trains the spinal muscles while seated.

Sitness technology

The unique Sitness technology separates the rigid connection between the chair base and seat and creates a dynamic connection.

Soft Sitness technology

Two springy clasps under the seat create a soft swinging movement that moves the body forwards, backwards and sideways with the help of your own body weight.

The advantages of Sitness technologies

+ Exercises the back and spine
+ Relieves the intervertebral discs

Office Collection

Kids Collection

Sitness has been tested and approved – by the Healthy Back Campaign! Eight of our products have been tested by the AGR and awarded the ‘Tested & Recommended’ seal of approval! With our AGR-certified models, you can create the most important component of a healthy working environment. Our unique Sitness technology ensures three-dimensional sitting. The freedom of movement in every direction ensures more active sitting, which unconsciously trains the back muscles and prevents back pain.

Sitness X powerd by Felix Neureuther

Together with Felix Neureuther and his ‘Beweg dich schlau!’ project, we have exactly the same goal in mind: to promote movement from an early age!
For this reason, we have jointly launched a new Sitness collection that meets the requirements of our modern smartphone age – from school enrolment to adulthood.
