Panasonic unveiled the “No-Constraints Carpet”, an innovative hot carpet shaped like a furry snake in order to mimic the feel of a hot pet. The carpet’s luxurious coat of faux fur houses a set of smart heating elements that deliver warmth. These heating elements will only be activated when you cuddle it, ensuring no energy is wasted when it is not needed. The carpet is available in two sizes1.5 meters = 5 feet or 7 meters = 23 feet the carpet also makes an interesting sofa decoration when not being used as a heating device.
