I was a but concerned about the quality of this bed because I didn’t pay a lot for it, but I have to say I am not disappointed. True this isn’t a high end piece of furniture but it is pretty well made considering the price. Took about an hour to put together with 2 people, instructions were easy to follow. One thing we did differently was to pre-drill the holes when it came time to screw in the slats which made the process so much easier. 
The wood used in making this bed is not high end and there was a split in the frame that the slate attach to but it was towards the end and really didn’t affect the attachment of the slats. (See pictures)  The metal for the frame is a thinner metal, I would be concerned if I were really over weight. 
Overall, I am pleased with my purchase.
