This is an excellent bookcase - it's listed here as "Angy Bookcase" but it's from the Vasagle range of furniture, which is always of very good quality and lovely designs. They also have some of the best designed self-assembly instructions, with sturdy components, which makes assembling this and other furniture from the range really easy. 

Also the bookcase got delivered within two days of ordering, well before the estimated date, so thank you Wayfair for excellent service.
