Wow, I love this bookcase.  It looks great in my modern living room.  I bought it in Walnut to match my other mid-century furniture and am very happy with the color and quality of the wood.  My partner assembled it in about two hours - lots of individual pieces, but each is clearly marked.  Be sure and follow the instructions and assemble the unit from the bottom up.  It's quite heavy so best to assemble in the room where it will be placed, and have a second person available to help.  Highly recommend this beautiful piece!
