Had my machines on concrete, hardwood flooring, laminate, regular thick plush carpet, and arcade style thin carpet as listed above. The arcade carpet has been the best for comfort (warm), sound control (less echo and general noise), easy to slide pinballs but not so much that the machine will slide with nudges, ad quite frankly has a good look for a classic game room. As also stated by others in this thread it seems exceedingly durable and is relatively cheap. Shining black lights on carpet gives it a good look as most of them were designed for that and doesn’t cause reflection on machines. On the other hand, a shiny wood floor reflects lights in a cool way and looks classier but for all of the above stated reasons, I prefer the arcade low plush carpet.
Can’t remember what padding I put under it but I remember i put something waterproof and thin which is plenty comfortable. I put sliders under the feet to move and they are almost effortless to slide on the carpet
