A kind of wormwood mattress called "no charge".

This mattress uses specially treated wormwood or wormwood leaf filling materials. They are usually called "plug-in-free wormwood mattress" or "self-heating wormwood mattress".

The working principle of this mattress is that the effective components in wormwood or wormwood leaves can be released through body temperature, resulting in a slight sense of warmth, thus promoting blood circulation, soothing muscles and relieving discomfort. Compared with the mattress that needs charging, this kind of wormwood mattress is more convenient and does not need external energy supply.

It should be noted that everyone's somatosensory temperature and use effect may be different, and the specific effect and warm feeling may vary from person to person. If you consider using this kind of mattress, it is recommended to choose a reputable brand and understand the characteristics and performance of the product before buying.
