| A. | Tetra Tea Tree mattresses have been tested by Unisearch NSW and the “results showed that for the tea tree packing normally found in the product (i.e. up to 0.056 g/cm3), there was very little resistance to air flow through the material (i.e. decrease in air flow of less than 4%). These results indicate that the tea tree bark in the pillows and mattresses offers very little resistance to air flow at the normal packing densities found in the products.” However all care should be taken. |
