This ergonomic seat stool is designed as a dynamic solution for modern work environments, particularly for use at sit-stand desks. The construction is based on a convex base that allows for 360° rotation and tilting movements to promote active sitting and reduce static strain. The vertical positioning is achieved through an integrated gas spring mechanism that enables stepless height adjustment while seated. A fabric-padded seat provides the necessary pressure relief, while shock-absorbing nylon wheels ensure mobility in the space while maintaining stability.
