It's a wonderful play mat because safe and completely non-toxic mats are hard to come by, I learned this after doing a lot of research into trying to find the best mat. We love that this particular one is made with 100% Certified Organic Cotton fabric and that its size covers a good amount of area. We like that it doesn't slide around on the wood. The only thing about the mat that is not as appealing as the rest is its maintenance; after cleaning the cover it's not easy to get the padding back in the cover perfectly aligned and without bumps. But I guess that's because it's an all-cotton padding. Also, the zipper gets stuck and it could be more hidden because our son found it with ease. Overall, it's awesome for our boy's health and he enjoys the interesting patterns, and that's all that matters!
