This is a very substantial bookcase with  nice features that include front shelf brace and adjustable shelves.  A little tricky to assemble, just have to take your time and keep looking ahead in the instructions.  It's not quite as tall as I thought, but it is the 71" as advertised.  The only weak point is the backing, it is a printed cardboard and it just does not sit flat.  I fixed that by replacing the back with my own 1/4 plywood that I painted black.

Pros: Looks very solid and substantial, looks like a piece of fine furniture
Cons: Tricky assembly, cardboard backing
