Keyboard stands vs thick carpet

[Simpo Two]

I bought one of those cheap X-shape stands to go under my new keyboard: http://www.amazon.co.uk/Tiger-Collapsible-Folding-...

However, as my carpet is new and rather thick, as feared the stand wobbles back and forth significantly. Are there any designs of stand which would be more stable, or perhaps have 'pins' on the feet to help them bite through the pile a bit like speaker stands? What about one of these: http://www.amazon.co.uk/Stagg-MXS-A1-Adjustable-Mi...

Thanks!
