Eighteen EVA foam puzzle tiles interlock to create a cushioned exercise surface that helps reduce joint strain and absorb noise during workouts. Each 24 x 24 x 0.6 in tile connects edge to edge so you can cover specific areas of your room and reshape the layout as your training needs change. The textured surface adds grip to help prevent slips while you move through yoga, pilates, weightlifting, or general fitness routines, and it also helps protect hard floors from scratches.
