@zhiyong.lee3: Why has the compression mattress become so popular recently? The main purpose is to save transportation costs; Standard mattresses are basically 0.8cbm per piece. The compressed mattress weighs only 0.14 cbm/pcs. Transportation costs are greatly reduced; However, high-compression springs that have undergone secondary calcination must be used. In conjunction with high-compression sponge At present, only Foshan in China has such technology. It can be stored for a longer period of time, up to more than three years, and then bounce back without collapsing; If the sponge does not meet the standard, it will collapse and not bounce back; A reliable supplier will definitely help you control the quality at the source. #MattressManufacturer #MattressFactory #WholesaleMattress #MattressSupplier #CustomMattress
