Can this Marley be installed on top of a carpeted floor?

We recommend using Rosco's Adagio Rolls over any hard flat surface like concrete, plywood, OSB, etc. You can use these rolls over commercial carpet, but if installing over a plush carpet or a carpet with a thick pad, we recommend placing a 1/4" thick plywood board between the carpet and floor. This will help to prevent injury while using the floor.
