Thank you for looking. This is a kotatsu for pets. I bought it because it was cute, but my pet wouldn't go in it, so I'd like to give it to someone who will use it. I have opened and assembled it once, so please consider this before purchasing. The following is quoted from the product page: ● This item allows pets to spend comfortable time at home even in the cold season. ● You can create an entrance by fastening the snap buttons. ● The material on the back of the futon is soft and fluffy. ● It is a simple assembly type, so it can be stored compactly when not in use. ■Specifications■ Set contents: Legs x 4, Middle top plate x 1, Top plate x 1, Futon x 1, Assembly instructions ※ Heater is not included.
