We choose one office sitting standing crank not only for its great simplicity but also for its unreserved practicability, which allows for easy alternation between different work postures. Much easier to drive and fully adjustable, the desk sitting standing manual is an ideal solution for adapting a workstation to a rotary according to the tasks in progress.  All you need to do is turn a light-voltage crank to define the optimal height of its tray. Positioning his work plan according to his morphology will never have been so simple!
