The ProSource Exercise Puzzle Mat creates a comfortable, durable surface for workouts and exercise equipment while protecting your floors. The interlocking foam mats are made from dense EVA foam which absorbs impact and noise during workouts and provides a soft surface for exercises like push-ups and crunches. Easy-to-assemble interlocking foam floor pads cover 24 square feet with end borders for a clean, finished look. Each tile is thick from the highest point of the texture. It comes in three color options and is great for garages, fitness rooms, gyms, CrossFit, children's play areas, and other hard floors. Soft foam puzzle mat contains no phthalates.
