This Interlocking Exercise Mats are made of high-density EVA foam which absorbs impact and noise during workouts and provides a soft surface for exercises like push-ups and crunches. The 1/2'' thick premium mat comfortably cushions the spine, hips, knees, and elbows on hard floors. Easy-to-assemble interlocking foam floor pads cover 24, 48, or 96 square feet with end borders for a clean, finished look. Lightweight, and easy to clean, great for use in garages, gyms, home fitness rooms, or even children’s play areas. Lightweight puzzle pieces connect quickly, and can be disassembled just as simply for quick storage. ★Please Note: The package will be shipped out separately as 2 boxes.
