Make any floor surface soft for your little one with this set of six interlocking foam floor mats from Sassy. Each mat is 16 inches square and includes a pop-out play piece. Bright, bold colors and fun shapes are sure to engage your baby as she grows. When snapped together, this mat covers a total of ten square feet, and it is expandable when you purchase additional sets. These mats use Microban technology, which fights the growth of stain and odor causing bacteria, mold and mildew.
