I have purchased items from Mayfair before and quite happy with the items, until receiving this bookcase which I can only describe as terrible quality and pure rubbish, the unit is made out of very cheap and nasty soft wood, the dowel that were supplied rattle in the holes  as they are far too small for the holes or visa versa, the screws bent when trying to install them and don't hit the brass pins to hard as they will also bend, the wood is so soft when you install the screws the wood is so soft you cannot tighten too hard, I eventually assembled the unit using a very strong glue and using my own screws and pins, the instructions are also not readable poor photocopy, the finished bookshelf looks cheap and nasty my own fault for buying a flatpack which was not a cheap price just the quality
