Do Ereada® mats get hot to the touch when they heat up?

It depends on the temperature level. The mat can feel hot to the touch when it is set to higher temperature levels.

It also depends on the mat model. Purple Ereada® amethyst mats and Ereada® Gemstone mats, where the crystals are covered with mesh fabric, usually feel warmer to the touch than the Classic Brown Ereada® amethyst mats, where the crystals are covered with a layer of soft eco-suede.

Surface temperature also depends on whether the heat is dissipating or being retained. The mat will feel much warmer when you are lying on it or when it is covered with a blanket.

It is very important to cover the mat completely while it is preheating. If the mat is only partially covered, the temperature sensors located in different layers of the mat may report inconsistent readings to the controller.

This may cause the controller to lose calibration and operate incorrectly or malfunction.

For this reason, always cover the mat completely while it is preheating to the selected temperature level.
