Great book case...the box is super heavy, but thankfully my husband managed to get it upstairs without needing my help. Was pretty easy to put together, a lot of pieces but got it done in under an hour. Pro tip....make sure all the holes are facing the back when putting together, I missed that and only noticed after putting the unit half together so had to start all over....luckily the screws can go in and out without causing any damage. Looks great with a mixture of books and ornaments, but not sure it could handle the weight if filled with heavy books. Definitely attach it to the wall if you can.
