The actual functions & appearance of your chair/arm may differ significantly from the video & illustration shown above.

Workstools shouldn't require so much attention that adjusting them becomes a job unto itself. Office Master's low-maintenance, easy-to-clean and affordable workstools are the perfect solution for any industrial workplace or specialty application.

In particular, office master WS16 is a great choice because of its unique base and seat tilting feature which make the WS16 a perfect choice for sit/stand applications.

Please note that the WS16 stool is for indoor use only and chemical cleaning is not recommended. For longevity of the stool, avoid round the clock usage that is typical of shift work environments (multiple rotating/consecutive shifts).
