Basically a chair without legs. Is there a site from which I can order one?
They still do, it is called a kotatsu, a table similar in dimension to a coffee table but with a built in heater at the centre, the table itself is covered with a quilt that extends down, keeping the heat. It is great in cold winter days. And yes, it has been around for a long time, before electric versions you would have the coal/amber one. Japanese houses were very well ventilated, the danger of carbon monoxide poisoning was minimal.
This Site Might Help You. RE: where to find kotatsu chairs? Basically a chair without legs. Is there a site from which I can order...
A thick quilt is stretched over the top of the table, with the edges tangling the half meter or so to the floor. This traps the heat (and all the gases from the heater) underneath the table. This would seem to solve the problem at least temporarily: all the nasty carbon monoxide is contained out of the way of human noses.
Amazon has some. Go to Home and Kitchen and look for Zaisu Japanese style floor chair Z5150A. They're $89.00 each. They're sold by the House of Rice Store. This style of chair is called Zaisu.
