Our standing desk can be raised and lowered just by pushing a button on a remote. However unlike many standing desks ours can be set to be raised to a fixed point and stop automatically. It can then be lowered to a fixed point and stop automatically too.
So you can have 4 stop settings. The benefit is that if more than 1 person is using the desk each person can have their favourite height set and can return to exactly that height each time.
