We had a spare glass top and wanted to put it to use. The glass measured 50 inches by 30 inches. We weren't sure if our glass top would be adequately supported by this base (the base is pretty light and the glass is heavy). However, it all worked out. If you push down fairly hard at one end, the other end starts to rise a bit but for everyday use it isn't an issue. Ideally, the base would be a bit heavier given the price but it does look very nice. I would have given 5 starts if it were 25% cheaper, but then again table bases seem to be pricey.
