So glad I stumbled across these bearings! I built a reinforced concrete coffee table with a solid wood base that easily weighs at least 300 pounds. I wanted the table to be easy to move, but I didn't want to spoil its appearance with unsightly wheels or risk someone breaking a toe. These bearings are perfect for this job! They sit unobtrusively on the underside of the table legs and only raise them slightly off the floor so that the toes are not endangered. Even my 115 lb wife can now move it in any direction with ease. I would definitely recommend them and will use them again on my next project!
