This is simply rug. Heed the "most helpful" review that gave it one star. This rug sheds like crazy. Not only my toddler's room have carpet fibers all over, they spread all over the entire second floor. My daughter had been having upper respiratory problems (sneezing, coughing, runny nose) ever since we put the rug in her room. We only used a light vacuum on it since heavy duty vacuums can exacerbate shedding. After we removed the rug from the second floor altogether and put it in our living room where there's a Honeywell air purifier running during the day, my daughter's respiratory problems completely stopped.
