After purchasing the sofa, it took me a long time to assemble it. Love it!
But I found that the outer packaging of the sofa was somewhat damaged due to transportation, resulting in some scratches on the left side of the sofa.
Because it was out of time, the website customer service could not help me. I tried to email directly the email address on the sofa's outer packaging. To my surprise, I got a reply within a day. After determining the problem, a replacement part was sent immediately. Very efficient! And I was told that I could contact factory customer service anytime there was a problem with the sofa. 
Highly recommend to everyone that if you have any problems beyond one month, contact the email address on the outer packaging directly!
