The assembly was easy. We love how heavy the bookcase is. The colors are bright and festive. We bought this for our 3 year old grandson for his little "cave" under the stairs in our new home. We are very pleased with it. We have not put books on it yet, but the shelves are thick and should hold his books without sagging. We are considering buying the matching table & chair set to complement the bookcase. We really like the fact that there are hooks on the backside to attach to the wall. Nice safety feature. We are glad we bought it. 

Pros: Heavy. Shelves should not sag. Colors are bright. Like the fact that this is gender neutral as our daughter-in-law is pregnant with a little girl. 
Cons: None at this time. Need a year to see if there are any cons.
