Speaker Stands

I have Acoustic Vienna Beethovens with spikes. I have a marble floor. I slide the speakers out when I sit to listen to them, then slide them out of the way when I'm done. Spikes scratch marble. I wanted to know if anyone knows of any thin, non-raised, flat stands, almost like amp stands, that I might set the speakers on. I thought about using flat cork tile or other materials, and putting furniture slides under them. Any suggestions where to find a suitable speaker stand or construction ideas. Thanx
