While this item is made of real wood, not HDF, it is a bit flimsy.  The wood is a soft wood, not oak or maple or hickory, and thus doesn't have great density.  I'm a bit worried about the tiny screws provided for the hinges, if they will stay screwed in over time.  The entire assembly took 5 minutes, since it essentially is held together by just 4 screws.  As such the structure is simple and straightforward.  I am however going to modify it be installing better support on the sides of the lid, and by adding a center divider for supporting the lid vertically.  Sooner or later someone is going to try sitting on the lid, and I doubt in its current form it would support much weight.  Wayfair stated a weight limit of 100lbs, I can double or tripple that with a center support.  Other than these things, it is a good box, looks good in the room, and will serve to keep my grandson's toys stored neatly in one place.
