This must be #4 of car hammocks for dogs that I have bought and tried in the last 10 years. Before, I got the regular soft ones, which required me to fill the space between the front and the back seats with something so that one or two large dogs would not be too heavy for the hammock and cause tear.
This one is an actual seat EXTENDER with a sturdy 3-part foldable bottom. Not only does it help to keep your car clean from doggy hair, saliva and other possible whoopsies, but it serves as an actual relatively sturdy platform, so your fur ball can be as comfortable as possible during any car ride. The side parts can be zippered up and attached to the handle above the window via a strap on both sides, so your dog will be in his own 'travel compartment'.
Teddy old dog with arthritis but also a serial shedder. Knowing he would be very comfortable while keeping most of his hair inside this special area, was a much appreciated convenience on this long drive. The hammock was secured with the typical headrest and seat straps. Teddy appreciated the additional non-slip blanket atop the extender. As you can see, there is a large mesh section towards the front of the car, so additional air from the vents is guaranteed. Apparently it also makes a great headrest for Mr Floof.
At every overnight stop, I would took that hammock out and shook the shedded hair off. Easy peasy. Only takes a few minutes to get do and get it back in place. I highly recommend this seat extension hammock.
Well made, comes with a nice carrying case - dog loves it - and I do too since it now sips my back seat upholstery from getting coated in her hairs. I drive an 08 tundra and the center console bubbles into the back area so it’s tighter there (and bows slightly downward) than behind the seats - a small thing which is why I still have it 5 stars.

The back seat cover is solid and durable.
COPRISEDILE è molto bello comodo e spazioso, mi sembra buono come prodotto, volevo solo capire una cosa siccome quando lho preso c'era scritto che poteva salire anche una persona nel sedile di dietro insieme al cane ma non riesco a capire cone si sposta il coprisedile, qualcuno mi può rispondere?
