This bookshelves is very well designed and sturdy. There is a clear manual book, and it took my husband half an hour to get it assembled.  He only needed a Phillips screwdriver, and he was able to complete the bookshelves all by himself. Hardwares and accessories were included, along with extra for backup. Shelves are well design and do not have any gap opening. It's very beautiful bookshelves and it looks vintage.
