Oversea maintenance:

 

         For foreign customers, door-to-door maintenance is impossible because of the geographical reasons. Please forgive us. Our company promises you that the materials used won’t appear quality problem and you can buy at ease. The generators in the sofas of power-driven type are guaranteed for five years, quality of which is the best one in this industry at present. Few of them won’t work. If the remote control of few generators contact loose, we can send you a new one to change by yourself. And we can guide you through the telephone. What you need to do is to open the cloth at the bottom of sofa, and then replace it just like the replacement of a battery, which is very easy.
