I bought two stools with drawers and nice wooden legs. What I didn't realize was that once I put things in ottomans, they were too heavy to move in any way, so......I thought of wheels. Luckily the legs came off easily. This mark looked like it could hold some weight and could be applied by a clumsy woman over 80. I have enough hand to have an electric drill so I can drill holes. I screwed in the screws by hand. Failed exercise in this part. It took a bit of muscle power, but the wheels work beautifully. I don't understand why all ottomans come with wheels, but since there aren't any, these wheels might be the answer.
