Grobag Egg, the colour changing digital room thermometer is another clever innovation from the people who brought you Grobag baby sleeping bags. Room temperature is vital in creating a comfortable and safe sleeping environment for a baby and health professionals recommend it should be maintained at 16-20 C.

The patented Grobag Egg glows yellow if the room temperature is within recommended guidelines (16-20 C). If the room temperature is outside this range the colour changes and can be used as a guide for parents or carers to take action to cool or heat the room, or to adjust the baby's bedding or clothing.

No other thermometer in the world gives parents such a simple colour warning system, coupled with a fully visible digital readout of their children's room temperature.
