I assembled it on my own in a few minutes, because it only has a few screws to turn in and 2 hinges for the both legs premounted.
You have to fix your piano only on the both holder mounted on the legs from the stand.
5 stars for the easy handling.
So far, it stands very good, and when you´re playing very, very harder, it still does standing and holding the piano, but it wiggles much around.
