I initially bought four 8 1/2 x 11 paper holders. My intention was to put them in a cabinet that I had. I really didn't take into consideration of the weight, so I became concerned that they might be too heavy for the intended use. So I then had 4 paper holders to stack on each other. I was really having a problem coming up with a way to lift them up off the floor. Imagine my delight when I went on the website and saw the rolling bases! I couldn't order it fast enough!!! I now have it in place and am no longer fretting about them being on the floor. Great craftsmanship!!!! Love it!!!!!
