I haven't slept on it yet, as it is for my guest room.  But I was incredibly impressed with the packing, instructions (yes, the instructions), and the sturdiness.  I put the bed together myself in about an hour or so.  It would have been less if I'd had some minor assistance just keeping some of the pieces straight while I tightened the screws.  But the instructions were clear, the parts were labeled so that there was literally no way to mess it up, and they provided a sweet little ratchet wrench (in addition to the allen wrench) to tighten the screws.  The slats also are secured by a velcro strip on both the slats and the bed frame.  It keeps them from moving around.  Looks great and feels sturdy.  Love it for my coastal themed guest room.
