First, I saw a detached piece As soon as I opened the package. I dont know where that is from but obviously it looks like it came a welded place so no way to fix at home.
2. Second, there is a significant scratch in the visible wooden piece.
Still, I am hoping at least I can sleep that is the main function of the bed and tried to assemble it.
And third, I am stuck in the very first step to assemble where I have to screw the No.1 piece and No.2 piece. As you can see in the photo, there is a defect in the screw groove (extra metal left). I cant even complete the first step of the assembly.

I’ll return this as soon as possible and will see how that return process goes and update later guys.
