COSTWAY 4-Tier Wooden Bookshelf, S-shaped Cube Storage Bookcase Display Stand with Anti-tipping Device, Freestanding Geometric Shelving Unit Room Divider for Living Room Bedroom Office (White)

I had a lot of difficulty putting this bookcase together, not in the way because of the instructions but the screw connecting cogs (only way I can describe them) would not connect to the screws and would turn round and round. Twice the bookcase came apart while I was trying to assemble it and in the end in order to keep things together I had to use wood glue and the last part which is the section (no.14 on the instructions) I ended up removing as the screws would not keep it in place as it hangs down and just kept falling off. Not happy with this product but was going to take too long to dismantle and send back. Waste of money to be honest.
