This shelf is the perfect design solution for my living room wall.  I like that it's mountable, which saves floor space and can be positioned at any height desired.  I stacked DVDs horizontally on all four shelves, which created a pleasing and subtle graphic effect on a formerly blank space.  It also freed up space inside my TV console, which is a bonus.  The assembly was not at all complicated, but it took some time to manually screw in all the hardware (15 screws).  Mounting the unit to the wall was where it got challenging.  It required messuring and leveling and several tries to get it done.  If not for that, I'd give it five stars.  It's a sturdy and functional piece of furniture.
