Parents, these interlocking foam play mats are perfect for creating a safe play area for your little ones! Each tile measures 30x30x1cm (about 11.8x11.8x0.4 inches), and the 18-piece set covers a nice 172x87cm area - perfect for a good-sized play space. The 1cm thickness provides excellent cushioning against hard floors, protecting those little knees and elbows during playtime. Made from safe, non-toxic foam that's BPA-free, phthalate-free, and lead-free - meeting both US and European safety standards. The interlocking design makes assembly super easy - just connect the puzzle-like pieces together to create your desired size and shape. Cleaning is simple too - just wipe with a damp cloth and mild soap when needed. The strong flexibility means they can handle active play without tearing or losing shape. Great for so many uses: baby play areas, exercise spaces, yoga mats, or general floor protection under furniture. The bright colors and puzzle design are engaging for kids while being practical for parents. Note: these mats work with other MQIAOHAM brand mats but might not be compatible with other brands due to slight size differences. The quality feels substantial - not that cheap, flimsy foam that falls apart quickly. Whether you're creating a nursery play area, protecting your floors from toy damage, or just want a comfortable surface for your little one to crawl and play on, these mats deliver both safety and functionality!
