This is a very sturdy, very functional, very fun bed.  I got it for my son's new big-boy room because I didn't have room for a separate book shelf and he has a TON of books.  It works perfectly and he thinks it's the coolest to sleep on top of his books.  The bed was relatively easy to put together, but took about 3 hours (my husband and I did it together). It's a great piece of furniture and I highly recommend it.
