I ordered this over a year ago, and was hoping I’d be able to work with it, but this is not the case.   The bookcase did not rest against the wall ever.   In its first location, even with using the wall fasteners, the bookcase was never flush with the wall as designed.   After moving it, it became wobbly and there is no way to position it to put the fasteners in another wall... no matter how far or close the base is to the wall.   

I love the design, but this is not a good piece of furniture.   Frankly, at least this one is a bit of a safety hazard and will be recycled.
