There are a number of things a home owner should do in order to make sure any furniture that's put out in the back yard is well suited to enduring the inclement weather that might hit the area during the winter and colder months. Since moving a bunch of rustic tables and other furniture inside every winter isn't really practical. There are some great protective coatings that can be used for exterior furniture and for the heavy items that must stay outdoors these coatings can ensure the furniture survives the winter while things like placemats and cushions can be brought inside.
