For anyone who is interested, I telephone the Customer Care line at 1-800-458-8407 regarding Sunbeam Patio Furniture. This line was manufactured under license by Sunlite Furniture - location unknown. This company went out of business approximately 6 yrs ago. So all of us who are looking for parts can either make do with substitutions or forget it and just replace the set or piece. I, too, am looking for the two plastic rings that hold the table legs together and hold the umbrella in place. I guess I will try a piece of PVC pipe.
