Japanese people generally value high quality products, and these come at a price. At big sites like Amazon kotatsu of different prices and qualities can be found. When you buy a complete set you usually get a discount compared to buying the table, futon and heater seperately. Since sets can be quite large, it can happen that the costs of sending the kotatsu overseas take up a large portion of the total price. However, I am convinced that if you find the right kotatsu for you it will give you a Chairs for Kotatsu lifetime of pleasure, warmth and comfort! One of my mother her friends bought a kotatsu recently, and she told me that since she bought it her family spend more time together, watching television and playing games together while enjoying the warmth of the kotatsu. Of course this only works well during cold winter days ;).
There are different kind of kotatsu tables available on the market. The most important difference between the various tables that are used for kotatsus are the height and the size of the surfaces of the table top. One important thing that needs to be considered is if the table will be used for other purposes as well. Some kotatsu tables allow the option to be used as a normal table, or even as a desk when the futon is removed. The traditional Japanese heater tables are usually fairly low, at a height of about 40 centimeters or about 16 inches. It should be noted that some tables that can be ordered online come with a heater, while others come stand-alone and require you to purchase the heater separately.
The kotatsu heater is the beating heart of a traditional Japanese heater. In the older days heaters used to be small stoves or furnaces, which were heated using coal. However, this caused serious health and safety concerns. Nowadays practically all kotatsus are heated using electrical warmth elements. One should still be cautious not to accidentally touch the heat elements, as this can result in serious burns. Sometimes a heater stops functioning, in which case it needs to be replaced. This can easily be done by detaching the screws, and attaching a new heath element. Heaters come in both 120V and/or 230V configuration and can be bought separate from the futon and table.
