How can I differentiate mattresses with 20% increased quality from older mattresses?
It is impossible to define visually if mattress quality has been increased by 20%. Precise determination is made with special measurement equipment or via a production code inside the mattress. In addition, since February 2009, KYMDAN mattresses, lounge suits and beds have a 6-year warranty policy in Vietnam. There are absolutely no products remaining on the market to which former standards apply.
