We upgraded from a queen to a king with this bed and I could not be happier. With two of us putting it together, it took us just about an hour. It came with the right number of allen wrenches, one of each size, but we pulled out one more of each to make it a little more efficient. The instructions were clear, all the parts were there, they all fit together and I am absolutely in love with this bed.

It is incredibly sturdy, unlike most of my other beds I've had. The little shelf at the top is the perfect width for our wireless chargers to fit. We have a 10" mattress and it is the perfect height to hit the bottom of the upholstered part of the headboard with no gap and no overlap. 

I couldn't say enough good things about this bed. Absolutely the best.
