Police in Huizhou, Guangdong province, seized more than 1,000 counterfeit mattresses and semi-finished products, valued at about 10 million yuan ($1.6 million), from an illegal workshop.

The US mattress brand Serta was the biggest victim in the case, according to police, who announced their findings on May 28.

In mid-May the police's economic investigation detachment received complaints from consumers who suffered backache and neck discomfort and suspected that the products were fake, said Qiu Jinhui, the detachment chief, at the press briefing.

Huizhou police set up a special team and traced the illegal workshop to the village of Changbu, in Xinyu town.

On May 22, the police raided the workshop and caught seven suspects, including the man in charge, a 28-year-old surnamed Gan. The case is still under investigation.
