Review on IRONCK Bookshelf Double Wide 6-Tier 76" H, Open Large Bookcase, Industrial Style Shelves, Wood And Metal Bookshelves For Home Office, Easy Assembly by Marcus West

All you need to assemble this thing is an Allen wrench, sounds nice until you find your hand constantly hitting the beams or the smaller supports in between them, with only 15 degrees of movement and like 60 screws to put in, it's a hassle. Do yourself a huge favor and use a ratchet with an Allen wrench attachment. Otherwise they are good shelves, look great, I put a bunch of heavy books and other things on them and it doesn't budge, not even bolted to the wall either
