Weak.  In the specifications it states weight capacity 3000 pounds.  I wouldn't trust 500 pounds, let alone 3000.  When I was tightening the screws, the metal was bending inward...I'm a female, with arthritis in my fingers, I am not strong enough to cause that kind of bend.  To me, the metal is not thick enough.  Gratefully, it is just me sleeping on this bed.  I'm disappointed and feel that the description is not accurate.  I also noticed the legs at the foot of the bed had bent in at the angle insertion after I put my bed up on a block to raise the head of the bed due to acid reflux.  With just me on this bed at 190 pounds with the legs already showing stress, how in the world could it have the ability to hold 3000 pounds?
