We need one of theses for the lounge…
That would be cool. Is there anything special about the surface that the things slide on?
Level and slidey I suppose. Oasis Lounge had one if you wanted to see one in person… although it has been a couple of years since I have been there…
Super fine sand is spread really thin across the table. Other than that I don’t think there is anything other than a really smooth and really flat surface.
