Rocking chair with auto lock. If the chair is in rocking mode and the person stands up, it will automatically lock and stop rocking so the person can stand up easily and safely. As soon as the person sits down and touches the backrest, the chair will start rocking again. It can also be set to non-rocking mode. Reason for sale: My father's new place is already provided. I paid $1000.00 and I'm asking $400.00.
