Indeed the dimensions are not indicated, I confirm the previous opinion, it does well 100 cm wide and 200 cm long, and very thick. I have used it for rehabilitation after a foot surgery, and now he is my little girl to cavort, or us to do exercises. It is very comfortable and well cushioned by its thickness. Good is represented with two elastic to roll elastic which were not sold with, or at least they were not attached to the parcel. This is unfortunate because it will be convenient for storage. For me he is standing drove well in the bedroom of my little girl waiting to find wholesale and large elastic.
