our kids love their new bed! The construction is very solid. It took my husband a day to build it with the kids (would have been quicker on his own) and only needed another adult's help to lift the twin over the double bed. 
The wood finish off gassed for about a week, I didn't love the smell but it is gone now. You can leave the box open in a garage for a few days prior to assembly to avoid the smell. 
We are very happy with the purchase
