The Vevor puzzle exercise mat set includes 6 interlocking tiles designed to protect floors in home gyms, offices, workshops, and training spaces. Each mat features a rubber top layer for grip and a high-density EVA foam base for shock absorption and rebound. The thick construction helps reduce vibration and equipment noise while guarding against dents from heavy gear. Its interlocking design allows quick tool-free installation and flexible layout expansion. The gray-dot black finish offers a clean, professional look for workout or work areas.
