Just received this bookcase and put books in. It is all wood and fully assembled. The shelves are adjustable but requires a screwdriver to unscrew them from the pegs that secure the shelves to the frame. The bookshelf surfaces are smooth but unfinished.
Only 3 stars because the bottom is uneven and so requires shims for the bookcase to sit evenly on the floor. Sloppy construction for a $350 bookcase. We would have sent it back if we could not have found a way for it to sit evenly on the floor.
