videos below."Every tier can be tilted to virtually any degree to allow for a comfortable playing position
The forks of every tier can be made to stick straight out or at an angle
The height of every tier can be adjusted
The depth of every fork can be adjusted
The horisontal position of both forks of every tier can be adjusted independently in case you want to put a small keyboard on some tier and you need them to come together a bit and you don't want to put a shelf on there like I've done.
Just make sure to tighten the screws once in a while depending on how much you re-adjust the tiers. I haven't had any problems with this stand since I got it and I've had some really bulky stuff on there like a Roland Jupiter-8, Roland Jupiter-6 and Yamaha DX7 mark 1, all of which weigh in at about 15-20 kgs.
The frame of the stand is made of aluminium and the sockets interconnecting the frame is made out of plastic. The dimensions of the stand is (H x L x D): 170 cm x 150 cm x 50 cm.
