The protector is formed from a cut and scored blank which is folded to define a tube consisting of a pair of panels connected along a fold line and having an included angle which can vary according to the corner angle of the article of furniture. A panel extends from distal portions of each of said panels and laterally of the sides of the article, each of said panels being connected to flanking panels folded into facing relationship and having end flaps thereof folded over and under the furniture article. The ends of certain of the panels have flaps folded back upon the same to give extra thickness to the protector at the lower and upper ends of the article as desired.
