I just finished building it... have not yet purchased a mattress so I haven't used it yet.  For set up... I checked Q&A - it said it came with locking casters for the trundle.  Not accurate.  So that was disappointing as it was a deciding factor.  Some of the wood planks have cracked a bit.  Its raw wood and not sealed.  A couple of drill holes were covered by material that I had to cut open during set up.  It looks pretty so far though.  Will have to see how it holds up after adding mattresses.
