Love this mat. It's so light but plenty padded. I wouldn't want it any thinner/thicker.  It folds up so nicely.  Took it to the lake and it was great for lying over the grass.  The only think I'm not crazy about is the texture on top.  It leaves dents in my babies skin if she kneels on it very long.  Can't tell if it bothers her or not.  She is just starting to pull up so I'm hoping having this extra layer of protection will prevent some head bumps and bruises.
