I want to preface this by saying that my first impression is that this is a really nice bed. 
Shipping was fast and packaged very well.  No damage from that process like some others were unfortunate to experience. All items were accounted for. It’s fairly lightweight and it was pretty easy to assemble alone but if you have extra hands, the process would be much faster. 
With all that said, it seems sturdy but the slats are a bit too flexible individually. The appear  fine with weight distribution though. I still wouldn’t  flop around too hard on it. This part is just personal taste but I don’t like the wood grain type look of the headboard. 
For the price I paid for this bed frame though, I am very pleased. I didn’t give it five stars mainly because of the slats being questionable.
