This bed looks good.  I was surprised to see it's supposedly only good for 175lbs.  I didn't notice that until I looked it up after assembling and while wondering if I needed a thin board on top the slates so the mattress wouldn't sink in. 
 The mattress alone weighs 80lbs.  My teenage son is about 180lbs.  Seems fine so far.  I guess time will tell.  It took us about 1 hour to assemble.  Pretty easy compared to a lot of furniture I've assembled.  I was surprised it was a 4/5 difficulty.  It would have been difficult without the extra set of hands.  Only thing to improve would be to include a few black stickers to cover up some hardware in the back.  Part of the back of ours is visible.  Overall, I'm happy with this bed.
