The TOG rating system was launched by The Shirley Institute in the 1940s and is a way of measuring insulation properties but not comfort. A very similar method is used to get an R rating on insulation pink batts. TOG measures thermal resistance by using a large metal plate and a mechanism for measuring the air temperature above the quilt. The quilt is placed on the metal plate with a heat source underneath which heats to 33 degrees and time is measured as to how long it takes for the temperature above the quilt to reach the same temperature as below. This is why a brick or pink batt has a high TOG rating but is not comfortable to sleep under. People don't sleep under a flat-board like quilt, so the real test is warmth to weight and breathability.
