Don’t be scared of the small box.  I literally thought I received the wrong package, BUT the picture as shown fit in the slimmest box imaginable.  I’m 5’2” and dragged that box from the driveway to the garage, so I recommend 2 people needed to stage the parts. Assembly wasn’t too bad.  It came with slats for a box spring to sit on, but I have a freestanding adjustable bed, so I didn’t need them. If you have a freestanding bed, start with the headboard and the first set of side pcs first. Next position your bed inside the frame, then add a middle slat to hold the sides together, then finish off the remaining sides and footboard.  Overall 2hrs for assembly for a cute bed frame.
