Carpet squares for kids come in a number of colors and patterns and are available at FLOR.com. Wayfair sells a variety of carpet squares for children as well.
Child-themed carpet squares often feature the alphabet with each letter in a separate square on the carpet. These decorative items also may depict a plush train track scene so that children can play with toy cars and trucks on the carpet. Other carpet squares for kids' rooms feature animal print designs and stripes in bold colors. Carpet tiles can be large enough to cover a significant portion of the floor, or several carpet tiles can be put together to give the look of a large rug.
