was put together in about 1/2 hour.  the depth takes up almost no space, I put it next to door where I couldn't put any piece of furniture because it would be narrow if you walked and turned in the room.  this fit perfect there takes up almost no dept...love love it..kids have access to all their books...perfect..highly recommend..I did lots and lots of research nothing out there like this..it holds up to 85 books...super happy
