Glides Set Of 4 In the unlikely event you need to replace the glides, we offer them in sets of two. With a wide 2.5" base, these metal reinforced glides are strategically constructed to handle increased pressure from heavier mattresses and diffuse weight over a larger footprint. The high-impact plastic base prevents scratching or denting on hardwood floors. L : 23 - W : 13 - H : 13 - W : 18
