Great bookcase. The assembly instructions looked easy but that's not my thing so I purchased the assembly plan. The rep put it together in 25 minutes. It is sturdy and meets my needs for my home make-shift office. 
Just make sure when you have it delivered you have someone to help you get the box in your house. It is VERY heavy. Also, recommend assembling in the room where it will be placed. Good quality means nice and heavy. :)
