Vibe Metal Bed Frame

It was not packaged well, I actually thought it was a return. Plastic wrapping inside had holes in it. I was able to put the headboard and footboard together fairly easily but step 3 was totally missing. I picked it up on step 4 but it was definitely confusing. I finally completed it- all the hardware and pieces were there. It looks nice in my room and seems to be sturdy. I like the extra room under the bed.

It’s a very nice bed frame for the cost. The only thing that’s a problem is the mattress wants to slide off the foundation. Not sure what would help it from sliding.

I like the bed one of the end rails will not thread the screw all into it at this point I just put this together yesterday and do not know how I'm going to fix this situation
