Very sturdy and good quality. Instructions were good, on the whole, but a little ambiguous when it came to the sliding runners. I went with what I saw on the picture and it was perfect (especially when looking at number of hole to put screw in). Initially the sliding desk jutted out about an inch but that was due to sliding runners not fully extending. In and out a few times and the runners were then set correctly. On the whole, straight forward to put together but took a lot longer to make than anticipated. Looks fantastic and feels solid.
