Difficulty to put together:3/10 no broken nails here!
Time to put together: speak now Taylor's version in full 
I'm super duper not handy at all. It took some trial and error for me but I didn't need to Google anything it was so easy to put together with minimal trial and error. It's big and sturdy. I'm about 250 and I could lean on the slats as I was putting it together with no creaking or anything. Highly recommend.
