This is a two tier keyboard stand that is high quality and very convenient to use. The height and width are adjustable for both the tiers. In fact you can even adjust the angle of the above tier. Should you wish to have it as a single tier; you can unscrew the arms of the upper tier and remove them completely.
It does require a little assembly on your part but nothing extraordinary. If you follow the guidelines you will be done in less than 15 minutes. This one is still fairly lightweight and extremely sturdy.
