Delivery from Koala etc, five stars, but unit itself two stars, it needs modifications, or a v high working desk to fit legs beneath... cross bars in middle and at the bottom are v poor design, and obstruct leg space, so removed!!
My working desk is low, a clearance of only 68cm, and this height is necessary to ensure keyboard and mouse are at ergonomic height. I put the keyboard (standard Roland weighted 88 keys thing) on the frame, without the wooden top. A way to secure it (eg Velcro) would be good, but not absolutely necessary.
To fit my feet under, I removed the lower bar, to pushed the sustain pedal back a little.
I'd redesign it so there isnt a cross bar in the middle, or at the bottom, ie at the top rear, away from knees, or even a flat plate, with no height... and 90 degree brackets at either side, away from knees, to improve tortional stability. But, it's stable without the lower bar, moves in and out smoothly, even on carpet, wheels are good.
The instructions arent clear on which piece is which, the zoomed elements are no clearer on the print (an online zoomable pdf would be better), but a simple enough unit to assemble without instructions.
Can't get away from the fact that this should be much cheaper, maybe half the price? But no alternative available that will drop to the required (low) height.
