In a square cabin, heat rises and pools against the ceiling, leaving your feet cold while your head is too hot. The curved walls send heat back down and around, so it circulates through the cabin instead of collecting at the top, and the room reaches an even temperature throughout. Less air to heat also means it gets there faster: 175–185°F in 45 to 60 minutes from cold.\u003c\/p\u003e\n\u003cp\u003eA half-view window runs across the front so you can see out while you sit, 304-grade stainless steel bands pull the staves tight, and a black asphalt shingle roof sheds weather and holds heat in.
