This is a great shelf, just as advertised. You can use it with or without the wheels. However the dimensions in the description are not the overall outside dimensions. Its actually 30 inches wide not 29. I bought two. Hoping to fit them side by side in a 59 inch space, and obviously they didnt fit. But I was able to assemble them as a double unit with 6 posts instead of 8, so that worked out. Accurate dimensions in the description would be great though..
