I really love this bookcase! It looks so good in my living room and is such a beautiful unique design! The instructions were very clear and easy to follow with all the pieces labelled. Me and my partner are both terrible at DIY and managed to put this together easily within 2 hours. We did have a problem with one of the shelves that did not fit in properly and so we had to give it a good whack with a hammer to get it to fit in, this resulted in the shelf not being flush with the rest of the unit. After putting the unit up and decorating it though, this is not noticeable.
This item was delivered in 2 separate parcels on 2 different days which was not specified by wayfair beforehand so this was a bit confusing! There was also some damage to the packaging but luckily this didn't affect the unit. 
Overall, I am very happy with this bookcase and would definitely recommend it!
