We did have some issues with assembly
1) One side piece, which should have been labeled a different letter, was labeled the same as another. 
2) one door hinge was installed crooked so would not slide in. We had to unscrew it and drill new holes for it to work. 
Assembly was fairly simple, does help to have a 2nd person. I honestly think it took longer to unpack and cleanup all the styrofoam than it did to assemble the piece.
