STOOLS - PERCHING, SADDLE AND WOBBLE STOOLS
Stools are a relitavely new ergonomic concept, helping you to use and strengthen the natural curve in your spine.
A perching stool works very well with a sit stand desk, giving you a half way position between sitting and standing.
The wobble stool allows you a vast range of heights, working well with any desk height but also giving you a lot of tilting movement.
