This studio desk is excellent, no doubt about that, looks stunning in the wood varient, quality is great, really easy to assemble (one man job), and a a good price point.
Take note.....If you want a reasonable playing position and/or you're planning on using this with a full on 88 key elephant like I am, then you will need to buy some risers for the main bench. I've got my Roland Fantom EX 88 on the roll out tray. As they're around 160mm high, the tray needs to be set much to low to be usable. Sure you can set your chair at the lowest setting, but then it's impossible to use the sustain peddle.
The solution : raise the height of the main bench so you can put the keyboard tray at its full height.
I think this is an oversight of the Wavebone. It really should come with more height adjustment capability for main desk.
