Assembly was very easy - took 20-30min.  It comes with a ratchet instead of a standard Allen wrench, which really speeded things up.  The wood used is not very thick, but it has a total of 9 legs, so I expect it will be sturdy.  It has a feature to prevent the mattress from slipping, which is a nice bonus.  The slats stick on with Velcro which is a clever way to do it.
