I had a friend who bought this rug for her nursery and immediately seeing it I loved the patterned. I ordered it for my two kids for their playroom shortly after. It is a thin rug which is why I am giving it 4 stars. However, I knew that before buying it and actually like that it is thin for building Legos, blocks, train tracks, etc...I have purchased a 1/2" felt/foam rug pad and it feels wonderful under the feet and on the knees when playing with the kids.
