Ergonomic active wobble stool with wheels featuring a unique DDF (Dual Density Foam) comfort seat with 360 DSM Dynamic Spine Motion technology (patent pending). Stay comfortable, energised, and enjoy an active workday with every move you make. A wider 60cm base prevents the stool tipping over and the motion technology can assist in strengthening your back and core muscles to improve wellbeing.
