W. Va. Code § 47-1A-11

(1) Every article of bedding made for sale, sold, or offered for sale shall have attached thereto a tag on which is stated the name of the filling material used, that such material used is new or secondhand and, when required to be sterilized, that such material has been sterilized and the number of the sterilization permit. Such tag shall also contain the name and address of the maker or the vendor and the registry number, as hereinafter provided, of the maker.

(2) In the description of the filling material used on any tag attached to an article of bedding, no term or designation intended or likely to mislead shall be used; but where such article contains more than one material, the amount of such materials shall be stated on the tag and there shall be no variance in excess of 10 percent from the amount stated on the tag: Provided, That no variance shall be allowed for filling material which is described as “all”, “pure”, “100%” or terms of similar import.

(3) A complete secondhand article of bedding which has not been remade or renovated may be sold “as is” without being sterilized, but the original tag shall be removed by the vendor and he or she shall attach a tag stating that the article is secondhand – “contents unknown”. This requirement shall not apply to articles sold at public auction, the sale of antique furniture, or to a private sale from the home of the owner direct to the purchaser: Provided, That the exceptions herein stated shall not authorize the sale of an article of bedding that has been exposed to infectious or contagious disease and which, after such exposure, has not been sterilized and approved for use.
