The furniture will be marital property that will be divided as part of the divorce proceeding. Since you both own the property there is little to prevent her from taking it now, subject to having to return some later, or possibly a monetary payment later depending on how the property is divided. If you file for divorce temporary orders can be addressed to prevent any immediate removal.
A general restraining order, not a domestic violence restraining order, can be sough to prevent the removal of the property. If divorce is something that will be filed, the action for a general restraining order will be added expenses that may not be needed.
