I even added all the sports mat beneath the area for more comfortable (at home it is placed on tiles).
The socks are very convenient! They prevent baby from rolling off the area and prevent some dust settle down, although such fast!
Only downside: the beginning, the colors bleed on socks (heels) baby: the colors remain bright, but they are still pretty!
Tip: take a sticky roller to dust the area, it is more effective than vacuuming
