Compared the price , Good sofa but there is Right side of Armrest part didnt match the slide part(different angle , length side by side slide part ).  So i claimed it to send me only the part. 
There was out of stock of that part so they sent me a whole new sofa again.  But the 2nd sofa has defected on the Left top of back seat (2cm scratched) too...(frustrated it) So i decided to make it with each half side of Sofa I had to uninstalled those two sofa  again and then had to assemble  them again.
Leftside seat  from the first sofa i received  Right seat sofa from 2nd . So finally i made one  sofa. Little tired and more works from what happened for 2 weeks to have sofa in my room.   . But i made it eventually .
