Nice queen side bed frame.  Assembly was simple, not too much improvisation required.  

Since the rails are metal your mattress may shift/slide on the frame.  Suggest applying a stip of felt or rubber across a few rails to hold the mattress from shifting. 

I used a power drill for assembly, using the provided Allen wrench would have been tiring and tripled the assembly time.

Overall, like the bed frame and suggest to purchase.
