The kotatsu futon is one of the three main elements that make up a kotatsu. (The other element are the kotatsu table and the kotatsu heater.) The purpose of the futon is to trap the heat generated by the heater so you can sit under a nice and warm blanket. A traditional Japanese kotatsu futon is pretty heavy and thick, but there are lighter ones available. (Usually these are of a lower quality and cheaper.) Depending on the quality you are looking for you should be able to find a suitable futon online. Always check to make sure your futon matches the size of your kotatsu table, otherwise the futon covers too little or too much of your table surface.
To help you choose from the various futons that you can buy online I made a small overview of the futons that are popular among the readers of this site.
