It's not really a hammock and really lays down on top of the seats, but I didn't know what else to call it.
This comes in very handy when you want to transport your dog or load stuff in the back and you don't want your seats to get messed up. It is tailored to fit specifically into the rear of an E46, and Installs in about a minute, with no tools. It has a bunch of little inserts that just stuff into place. Very cool unit. Used it for years. Excellent condition.
New $250
will sell $75 for plus shipping (i don't do USPS)
