This elegant, sleekly designed shelving unit was easy to assemble.  It has five shelves of different heights and depths (smaller at the top, larger at the bottom of the unit).  I put it together in less than a hour.  The finish on the wood is exceptional....friends ask where I bought this fine piece of furniture.  
Top shelf is 8 3/4" deep, 2nd shelf is 10" deep, 3rd shelf is 11 1/4" deep, 4th shelf is 12 1/2" deep, bottom shelf is 14 1/4" deep.  Width of whole unit is 29 1/2" including the sides. Total height is approx. 63-64" (I measured it on carpet.)   All you need is a screwdriver to put it together.  
Looks great, holds lots of books and other items.  Would purchase again !
