Hot Room for 2 — a sauna that folds into a yoga studio

Field notes

The design uses two 30 × 72-inch bench halves that fold into 4¾-inch wall pockets, then swing down into a rigid platform with no legs. The page proposes three temperature sensors at 78, 30, and 6 inches to test whether raising the floor practice improves the heat distribution at a 105 °F class temperature. It also describes a flat-shipping kit, ordinary 120 V power, and a claimed 1,000-pound design load, while marking the physical unit, suppliers, price, and ship date as unresolved.
