With my masterwork, I create a work base in the living space that provides a solution in the form of a furniture family in terms of both the ergonomic and health (physical and mental) aspects of computer activities. Attention is not focused on body position during work, it resulting posture “C”. Different personalities, different sitting positions are considered comfortable, multiple changes of position and incorrect posture can lead to serious spinal problems over time. The active seat provides a solution to this by releasing the doubly broken, right-angled seating position, increasing the angle between the spine and thighs and creating a resting standing-like posture while working. In addition, the seating surface itself does not have static support, so the user is constantly in motion, which has a positive effect not only on blood circulation but also on our posture and work-morale. The realization of individual preferences is supported by the free variability of different sizes and modules.
