How to secure a digital piano onto its stand?

[fenderstrat]

Hey guys, I just recently purchased a Yamaha P85 Digital Piano, and I bought an X stand seperately too. When I put the piano on the stand, I realised it slides around way too much. The underneath of the piano is not flat throughtout, with some slanted edges and stuff. The piano can easily slide from left to right when I place it on the stand, only to be stopped by some rubber pieces towards the far sides.

Is this a usual problem? Is there a way I could increase friction to secure the piano on the stand? Like rubber patches or something? Where's a gd place to get? Help appreciated! Thanks ppl! =)

Are the top bars of the X stand where you placed the piano wider than the bottom bars?

There should be rubber paddings on the stand itself to prevent slipping. These rubber pads are movable.
