We received the bed yesterday, ( earlier than anticipated) and like most of the other reviews stated it took no more than 2 hours to assemble. It pretty much assembled itself.  Not only is it a great bed for the price; it is a great bed for any price.  It has a rich look to it and my husband couldn't believe how well crafted the bed was/is. This bed is for my 3 year old "big boy" and he LOVES it.  I was a bit worried about being able to find a mattress that fit well and were comfortable.  What I ended up getting was 2 kids memory foam mattresses which are 7 inches deep.  They are a perfect fit.  Not to mention unbelievably comfortable.  If I had to think of a con it would be not being able to get my boys out of the crawl space.. Their new super and cool new fort. : )
