Selecting a foam dance subfloor from Greatmats gives you a dance floor underlayment that also works as an exercise floor. Homeowners can take advantage of this high density floor padding to create a safer place for workouts, because it protects the lower body joints of dancers and athletes. Our subfloor tiles work with almost any type of firm style of flooring over the top, if desired. This is an easy-to-assemble foam dance subfloor.
