Sturdy, however one of the bolts came loose on the shelf, and one of the feet wouldnt screw in because it was messed up. Also some of the bolts were mislabeled which confused me. However, it is now standing and working for my sewing machine. Just wouldve liked one where all the bolts worked. Also the metal bar that holds up the extension is too long and doesnt fit into the slot its supposed to, so I cant use it.
