The moisture content of the hotel furniture must not exceed 12%. If the moisture content is high, the wood tends to warp and deform. When the general consumer purchases, there is no test instrument, so you can use the hand-touch method to touch the underside or inside of the furniture without painting. If you feel damp, then the moisture content is at least 50% and you can't use it at all. Another way is to sprinkle a little water on the unpainted areas of the furniture wood. If there is no flooding or if it is immersed slowly, the water content is higher.
