My sofa is in the middle of the room, directly facing the TV.  Two 3-door cabinets fit very nicely behind it, without taking any floor space.  The top of the cabinet is the perfect height for placing drinks, popcorn, and the remote.  (I don't have a coffee table.)

The cabinet actually stores more than 216 DVD's, if you store some flat.  Or it can be used for a few dozen CD's or other items on the three half-height shelves.

Cabinet was easy to assemble and seems solid and sturdy.  Doors roll easily.
